Diagnosis is often delayed because of the presence of several clinical manifestations and the high prevalence of secondary bacterial infections. Few reports have attributed secondary bacterial infections in patients with TOM to commensal Neisseria. Thus, understanding the pathogenic mechanisms and clinical features of commensal Neisseria is important, considering its recent presentation as an infection-causing pathogen. Neisseria mucosa is a commensal inhabitant in humans and is generally considered non-pathogenic but can cause infection in rare cases. Here, we report an atypical secondary infection caused by Neisseria mucosa in an 81-year-old woman with TOM being treated for pulmonary tuberculosis. Direct purulent otorrhea smear microscopy revealed no acid-fast bacilli using Ziehl-Neelsen staining, whereas the phagocytosis of gram-negative cocci by white blood cells was confirmed using Gram staining. Otorrhea culture revealed the growth of N. mucosa. Subsequently, M. tuberculosis infection in the otorrhea was identified using a culture-based method. Vigilance is critical for the early detection of TOM to prevent further complications. This report raises awareness regarding TOM and provides insight into the pathogenicity of N. mucosa in otitis media.展开更多

Common symptoms of tuberculous otitis media(TOM) include otorrhoea, hearing loss, and multiple tympanic membrane perforations. Due to its rarity, the illness is frequently misdiagnosed. When a patient does not improve with standard antibacterial and antifungal treatment, this may be a possible diagnosis to explore. Complete healing is possible if the illness is diagnosed and treated timely to prevent consequences.展开更多

It is often secondary to nasopharyngitis, which favors the passage of infection through the Eustachian tube to the middle ear. The aim of our study was to improve the management of AOM in the Paediatric Department of the Hospital National Ignace Deen (Conakry). Patients and Methods: This was a prospective descriptive study lasting 6 months from 01 July to 31 December 2011;the study covered 525 cases out of a total of 6276 children, i.e. a frequency of 8.36%. Results: The most affected age group was 6 to 11 months. Males predominated (69.71%). 82.29% had a history of recurrent rhinopharyngitis. The most frequent reason for consultation was incessant crying (66.29%). Rhinopharyngitis and malaria were the most commonly associated pathologies (87.62% and 39.62% respectively). 72.19% of our patients were admitted with congestive AOM and received medical treatment. We recorded one case of otomastoiditis which was treated surgically. Conclusion: AOM is more common in children aged between 6 and 24 months. Good collaboration between paediatricians and ENT specialists is essential to reduce the morbidity of AOM.展开更多

In recent years, the incidence of otitis media has been rising globally, becoming a significant threat to human health. More and more studies have found that Toll-like receptor 4 (TLR4), as a member of the Toll-like receptor family, can promote the generation of inflammatory factors and is closely related to the body’s immune response and inflammatory response. Nuclear factor-κB p65 (NF-κB p65) is a nuclear transcription factor that can interact with various cytokines, growth factors, and apoptotic factors, participating in processes such as oxidative stress, apoptosis, and inflammation in the body [1]. This article elaborates on the structure, function, and signaling pathways of TLR4 and NF-κB p65 proteins in the pathogenesis of otitis media, aiming to provide more precise targets and better therapeutic efficacy for the diagnosis and treatment of otitis media. The role of inflammation in disease.展开更多

This study evaluates the clinical efficacy of amoxicillin + clavulanic acid in children with pharyngitis, acute otitis, or acute rhinosinusitis with suspected bacterial origin under normal office and home conditions. Methods: This was a real-life, prospective, observational, pharmacovigilance study. It included children of both sexes between 2 and 12 years old, with a diagnosis of Rhinopharyngitis (tonsillitis), Acute Otitis Media and Rhinosinusitis. The main effectiveness variable evaluated was reduction and time to resolution of symptoms. All patients received Amoxicillin/Clavulanic Acid suspension 600 mg/42.9 mg/5 mL at a dose of 90 mg/Kg/day in two doses, every 12 hours for 7 days. The evaluations were carried out at the beginning, at 72 hours (3rd day) and at 7 days. All patients underwent culture and antibiogram. Results: The majority of cultures were negative for pathogenic germs, suspecting unidentifiable germs, or viral etiology despite the rigorous selection of subjects following validated scores. The most frequently isolated germ was Staphylococcus aureus;growth of gram-negative bacteria was reported in 33.33% of the cultures. There was a significant improvement in symptoms in children with tonsillitis and rhinosinusitis from the first 72 hours of treatment, persisting until the 7 days. In the otitis media group, returning to normal by the tenth day. During the conduction of this investigation, no adverse effects associated with the prescribed therapy were reported.展开更多

More and more studies have shown that relevant cell proliferation and inflammation progression pathways play a role in the development of otitis media, such as the Jun amino-terminal protein kinase (JNK) mitogen-activated protein kinase (MAPK) signaling pathway, the NF-κB signaling pathway, and the PI3K/AKT/PTEN pathway, which are involved in the proliferation of the middle ear mucosa during otitis media, which affects the mucosal cilia, motor function, Eustachian tube function, and the mucosal ciliary function. These studies provide new ideas for the treatment of otitis media and further explore the feasibility of immunotherapy in the future treatment of otitis media. In this paper, we present a review of the latest research progress on the expression of various cytokines in otitis media.展开更多

Objective: To study cases of external otitis at the Mamou Regional Hospital. Materials and Methods: This was a prospective descriptive study conducted over a period of six (6) months from July 1st to December 31st, 2016. It included all patients admitted to the ENT department of the Mamou Regional Hospital. Results: During the study period, 712 patients were admitted to the department for various pathologies, of which 103 met our selection criteria, representing a frequency of 14.46%. The mean age of the patients was 33.74 years with a range of 1 to 90 years. Males predominated in the sample, accounting for 59.22%. The vast majority of patients resided in urban areas, constituting 61.17% of the sample. In our study, all patients consulted for otalgia (100%), and over half (53.39%) for hypoacusis. We formally identified rhinitis in 66.66% of cases, while diabetes was found in only 4 patients (11.11%). Otomycosis was the most commonly identified condition (53.39%), followed by furuncles (33.98%). Ear drops containing antibiotics were administered to all patients, although 66.60% received antibiotic therapy. Conclusion: External otitis is a relatively common condition, particularly among children and the elderly. Diagnosis can be made based on pain upon traction of the pinna and pressure on the tragus.展开更多

The purpose of this study was to determine whether clinical outcomes of NEO can be correlated to different infectious spread patterns.Methods: Retrospective chart review from 2010 to 2019 with NEO patients, who were divided into two cohorts: single spreading patterns(group A) or complex spreading patterns(group B) as diagnosed by CT.Clinical symptoms, diagnostic and treatment delay, course of disease, complications, and duration of antibiotic exposure were retrospectively collected from patient records.Results: 41 NEO patients were included, of which 27 patients belonged to group A(66%). The diseaserelated mortality rate was 12.2% among the entire cohort, no differences were found between group A and B. Higher rates of N.VII(42.9% vs 14.8% P = 0.047) and N. IX palsies were found in group B compared to group A(28.6% vs 3.7%, P = 0.039). The median duration of antibiotic use was significantly different for a complex spreading pattern, clinical recovery and hospitalizations. Complications were associated with higher diagnostic delay and with a complex spread pattern. The median duration of follow-up was 12.0(IQR 6.0-19.5) months.Conclusion: NEO is a severe disease, with significant mortality and morbidity(cranial nerve palsies). The radiological spread pattern may assist in predicting clinical outcome. Furthermore, complex spread patterns are associated with higher rates of clinical nerve palsies(N. VII and N.IX), complications, surgery rates and longer duration of antibiotic use. Diagnostic delay was associated with mortality, complications and facial palsies.展开更多

Method Forty cases of OME(45 ears) were randomly selected to receive intratympanic administration of Dexamethasone at 5 mg/ml(Group 1 or G1), Batroxobin at 1 BU/ml(Group 2 or G2) or Batroxobin at 2 BU/ml (Group 3 or G3). Pre-and post-treatment changes in clinical symptoms, the Air conduction Hearing Threshold (AHT) in pure tone audiometry and average AHT over 0.25 to 2 kHz were compared. Results Data from 31 cases(33 ears) were available for analysis. AHTs among three groups were similar prior to treatment(P > 0.05). The rate of normal hearing following treatment in G3 was 70% or 7 / 10, higher than in G1(41.7% or 5 / 12) and G2 (54.5% or 6 / 11)(P < 0.05). The rate of improvement following treatment was 81.8% or 9/11 and 80.0% or 8 / 10 in G2 and G3, respectively, higher than that in G1(50.0% or 6 / 12)(P < 0.05). Conclusions Therapeutic effects of intratympanic injection of Batroxobin on OME is superior to traditionally used Dexamethasone. In addition, higher concentration of Batroxobin appears to be superior to lower concentrations. These findings confirm that fibrinolysis plays a pivotal role in the pathogenesis of middle ear adhesion and that fibrinolytic medicine can prevent or reduce adhesion development in the middle ear.展开更多

Methods:...Objective: To report outcomes of balloon dilation Eustachian tuboplasty combined with tympanostomy tube insertion and middle ear pressure equalization therapy in treatment of recurrent secretory otitis media. Methods: Fifty one patients with recurrent secretory otitis media (62 ears) underwent balloon dilation of Eustachian tube and tympanic tube insertion under general anesthesia, followed by long term middle ear pressure equalization therapies. The Eustachian tube score (ETS) and Eustachian tube function questionnaire (ETDQ-7) were used for pre- and postoperative (up to 12 months) evaluation of Eustachian tube functions. Results: The mean ETS score was 2.34 ± 0.97 preoperatively, and 6.17 ± 1.54, 7.23 ± 1.62, 8.24 ± 1.97, and 7.63 ± 1.86 at 1, 3, 6 and 12 months postoperatively, respectively (P < 0.05). The ETDQ-7 score was 4.82 ± 1.07 preoperatively, and 2.20 ± 0.54, 2.32 ± 0.68, 2.53 ± 0.79, and 2.67 ± 0.76 at 1, 3, 6 and 12 months postoperatively, respectively (P < 0.05). Conclusion: Balloon dilation of Eustachian tube combined with tympanostomy and catheterization resulted in significant improvement of subjective symptoms and objective evaluation of Eustachian tube functions in most patients with recurrent secretory otitis media, as indicated by the ETS and ETDQ-7 scores, demonstrating high levels of efficacy and patient satisfaction.展开更多

This often leads to poor scholastic performances and difficult social interactions. The objective of this study was to identify asymptomatic cases of otitis media with effusion present in individuals with adenoid hypertrophy. Material and Methods: In a cross sectional study advocated in Justice K.S.Hegde Hospital, Karnataka India we evaluated one hundred patients above the age of three from August 2016 to December 2017. Candidates who presented with an adenoid nasopharyngeal ratio of more than 0.5 were selected for the study. Individuals who complained of otological symptoms were not considered for the study. Patients cleared of other pathological otological conditions were underwent audiological evaluation with pure tone audiometry and tympanometry for evaluating the middle ear status and hearing loss. Results: The study showed a total of 36% of patients evaluated presented with asymptomatic otitis media with effusion. In candidates who presented with a bilateral B tympanogram, 40% had significant conductive hearing loss of more than 25dB. Conclusion: An objective test such as impedance audiometry in all patients with adenoid hypertrophy would aid in the diagnosis of fluid in the middle ear, so that timely intervention can be done and possible complications be averted.展开更多

This disease frequently afflicts humans and is the major cause of hearing loss worldwide. OM continues to be one of the most challenging diseases in the medical field due to its diverse host targets and wide range of clinical manifestations. Substantial morbidity associated with OM is further exacerbated by high frequency of recurrent infections leading to chronic suppurative otitis media （CSOM）. Children have greater susceptibility to, and thus, suffer most frequently from OM, which can cause significant deterioration in quality of life. Genetic factors have been demonstrated, in large part by twin and family studies, to be key determinants of OM susceptibility. In this review, we summarize the current knowledge on immunity genes and selected variants that have been associated with predisposition to OM. In particular, polymorphisms in innate immunity and cytokine genes have been strongly linked with the risk of developing OM. Future studies employing state-of-the-art technologies, including next-generation sequencing （NGS）, will aid in the identification of novel genes associated with susceptibility to OM. This, in turn, will open up avenues for identifying high-risk individuals and designing novel therapeutic strategies based on precise targeting of these genes.展开更多

Material and methods:This is a retrospective review of records of 24children with bilateral profound sensorineural hearing loss and OME who were implanted during January 2011 to November 2014 in the Department of Otorhinolaryngology and Head and Neck Surgery at the PLA Hospital, using one-stage implantation via the facial recess approach and round window insertion. The incus was removed in 8 cases during the implantation procedure. Local infiltration of dexamethasone and adrenaline in the middle ear was also performed. Postoperative complications were examined. Preoperative and postoperative questionnaires including Categories of Auditory Performance (CAP), Speech Intelligibility Rating (SIR), and the Meaningful Auditory Integration Scale (MAIS) were collected. Results: All electrodes were implanted successfully without any immediate or delayed complications. Inflammatory changes of middle ear mucosa with effusion were noted in all implanted ears. The scores of post-implant CAP and SIR increased significantly in all 24 cases (t ? ?25.95 and ?14.09, respectively for CAP and SIR, p<0.05). Conclusions:One-stage CI via the facial recess approach with round window insertion is safe and effective in cochlear implant candidates with OME, as seen in the 24 children in our study who achieved improved auditory performance and speech intelligibility after CI.

文摘BACKGROUND Otitis media with effusion(OME),glue ear,serous otitis media,or secretory otitis media is a common paediatric condition.Two widely used surgical interventions for OME are myringotomy alone and myringotomy with tympanostomy tube.While both procedures aim to improve hearing outcomes,the efficacy of these approaches has been a subject of ongoing research and debate.AIM To compare the efficacy of myringotomy alone and myringotomy with tympa-nostomy tube.METHODS In this comparative study,66 patients diagnosed as OME meeting the inclusion criteria were selected via ear,nose and throat department.They were divided into two groups randomly,each of 33 patients.In the first group(Group A)myrin-gotomy alone was performed while in the second group(Group B)myringotomy with tympanostomy tube placement was performed.We observed hearing outcome by pure tone audiogram(PTA)pre operatively.Patients were followed up and re-assessed in outdoor patient department at 4th week postoperatively again by PTA.RESULTS The mean age of the patients in Group A was 10.96±2.76 SD but the mean age of the patients in Group B was 10.22±2.73 SD(P=0.1056).In Group A,males were 63.6%and females were 36.3%.Also in Group B,males were 63.6%and females were 36.3%(P=1.0).In group A,post operative hearing gain using pure tone audiometry at one month was 20.45±3.78 SD while in group B,post operative hearing gain using pure tone audiometry at one month was 23.84±3.69 SD(P=0.00005).However,ear discharge was noted in 3.03%cases in group A and 15.15%cases in group B(P=0.035).By applying independent t-test,the P<0.05 indicated that there is a significant association between Group B and hearing improvement at 4th week.CONCLUSION Our study concluded that myringotomy with tympanostomy tube seems to have better hearing results than myringotomy alone in treatment of OME.
文摘Tuberculous otitis media(TOM) is a rare manifestation caused by Mycobacterium tuberculosis with low incidence rates among extrapulmonary tuberculosis cases. Diagnosis is often delayed because of the presence of several clinical manifestations and the high prevalence of secondary bacterial infections. Few reports have attributed secondary bacterial infections in patients with TOM to commensal Neisseria. Thus, understanding the pathogenic mechanisms and clinical features of commensal Neisseria is important, considering its recent presentation as an infection-causing pathogen. Neisseria mucosa is a commensal inhabitant in humans and is generally considered non-pathogenic but can cause infection in rare cases. Here, we report an atypical secondary infection caused by Neisseria mucosa in an 81-year-old woman with TOM being treated for pulmonary tuberculosis. Direct purulent otorrhea smear microscopy revealed no acid-fast bacilli using Ziehl-Neelsen staining, whereas the phagocytosis of gram-negative cocci by white blood cells was confirmed using Gram staining. Otorrhea culture revealed the growth of N. mucosa. Subsequently, M. tuberculosis infection in the otorrhea was identified using a culture-based method. Vigilance is critical for the early detection of TOM to prevent further complications. This report raises awareness regarding TOM and provides insight into the pathogenicity of N. mucosa in otitis media.
文摘Although tuberculosis has become more common in recent years, it still accounts for just a small percentage of cases of chronic otitis media. Common symptoms of tuberculous otitis media(TOM) include otorrhoea, hearing loss, and multiple tympanic membrane perforations. Due to its rarity, the illness is frequently misdiagnosed. When a patient does not improve with standard antibacterial and antifungal treatment, this may be a possible diagnosis to explore. Complete healing is possible if the illness is diagnosed and treated timely to prevent consequences.
文摘Introduction: Acute otitis media is an acute inflammation of the mucosa of the middle ear cavities. It is often secondary to nasopharyngitis, which favors the passage of infection through the Eustachian tube to the middle ear. The aim of our study was to improve the management of AOM in the Paediatric Department of the Hospital National Ignace Deen (Conakry). Patients and Methods: This was a prospective descriptive study lasting 6 months from 01 July to 31 December 2011;the study covered 525 cases out of a total of 6276 children, i.e. a frequency of 8.36%. Results: The most affected age group was 6 to 11 months. Males predominated (69.71%). 82.29% had a history of recurrent rhinopharyngitis. The most frequent reason for consultation was incessant crying (66.29%). Rhinopharyngitis and malaria were the most commonly associated pathologies (87.62% and 39.62% respectively). 72.19% of our patients were admitted with congestive AOM and received medical treatment. We recorded one case of otomastoiditis which was treated surgically. Conclusion: AOM is more common in children aged between 6 and 24 months. Good collaboration between paediatricians and ENT specialists is essential to reduce the morbidity of AOM.
文摘The role of Toll-like receptor 4 (TLR4) and nuclear factor κB p65 (NF-κB p65) proteins in the pathogenesis of otitis media is explored. In recent years, the incidence of otitis media has been rising globally, becoming a significant threat to human health. More and more studies have found that Toll-like receptor 4 (TLR4), as a member of the Toll-like receptor family, can promote the generation of inflammatory factors and is closely related to the body’s immune response and inflammatory response. Nuclear factor-κB p65 (NF-κB p65) is a nuclear transcription factor that can interact with various cytokines, growth factors, and apoptotic factors, participating in processes such as oxidative stress, apoptosis, and inflammation in the body [1]. This article elaborates on the structure, function, and signaling pathways of TLR4 and NF-κB p65 proteins in the pathogenesis of otitis media, aiming to provide more precise targets and better therapeutic efficacy for the diagnosis and treatment of otitis media. The role of inflammation in disease.
文摘Real-world evidence (RWE) is clinical evidence on a medical product’s safety and efficacy that is generated using real-world data (RWD) resulting from routine healthcare delivery. This study evaluates the clinical efficacy of amoxicillin + clavulanic acid in children with pharyngitis, acute otitis, or acute rhinosinusitis with suspected bacterial origin under normal office and home conditions. Methods: This was a real-life, prospective, observational, pharmacovigilance study. It included children of both sexes between 2 and 12 years old, with a diagnosis of Rhinopharyngitis (tonsillitis), Acute Otitis Media and Rhinosinusitis. The main effectiveness variable evaluated was reduction and time to resolution of symptoms. All patients received Amoxicillin/Clavulanic Acid suspension 600 mg/42.9 mg/5 mL at a dose of 90 mg/Kg/day in two doses, every 12 hours for 7 days. The evaluations were carried out at the beginning, at 72 hours (3rd day) and at 7 days. All patients underwent culture and antibiogram. Results: The majority of cultures were negative for pathogenic germs, suspecting unidentifiable germs, or viral etiology despite the rigorous selection of subjects following validated scores. The most frequently isolated germ was Staphylococcus aureus;growth of gram-negative bacteria was reported in 33.33% of the cultures. There was a significant improvement in symptoms in children with tonsillitis and rhinosinusitis from the first 72 hours of treatment, persisting until the 7 days. In the otitis media group, returning to normal by the tenth day. During the conduction of this investigation, no adverse effects associated with the prescribed therapy were reported.
文摘The expression and clinical significance of relevant cytokines in otitis media (OM) are discussed, and the alterations to the pathological state of the otitis media mucosa are further understood through the study of cytokine transduction pathways. More and more studies have shown that relevant cell proliferation and inflammation progression pathways play a role in the development of otitis media, such as the Jun amino-terminal protein kinase (JNK) mitogen-activated protein kinase (MAPK) signaling pathway, the NF-κB signaling pathway, and the PI3K/AKT/PTEN pathway, which are involved in the proliferation of the middle ear mucosa during otitis media, which affects the mucosal cilia, motor function, Eustachian tube function, and the mucosal ciliary function. These studies provide new ideas for the treatment of otitis media and further explore the feasibility of immunotherapy in the future treatment of otitis media. In this paper, we present a review of the latest research progress on the expression of various cytokines in otitis media.
文摘Introduction: External otitis (OE) is an acute or chronic inflammation or infection of the external ear resulting from an imbalance in the external auditory canal secondary to microtrauma, maceration, eczema, or a foreign body in the external auditory canal. Objective: To study cases of external otitis at the Mamou Regional Hospital. Materials and Methods: This was a prospective descriptive study conducted over a period of six (6) months from July 1st to December 31st, 2016. It included all patients admitted to the ENT department of the Mamou Regional Hospital. Results: During the study period, 712 patients were admitted to the department for various pathologies, of which 103 met our selection criteria, representing a frequency of 14.46%. The mean age of the patients was 33.74 years with a range of 1 to 90 years. Males predominated in the sample, accounting for 59.22%. The vast majority of patients resided in urban areas, constituting 61.17% of the sample. In our study, all patients consulted for otalgia (100%), and over half (53.39%) for hypoacusis. We formally identified rhinitis in 66.66% of cases, while diabetes was found in only 4 patients (11.11%). Otomycosis was the most commonly identified condition (53.39%), followed by furuncles (33.98%). Ear drops containing antibiotics were administered to all patients, although 66.60% received antibiotic therapy. Conclusion: External otitis is a relatively common condition, particularly among children and the elderly. Diagnosis can be made based on pain upon traction of the pinna and pressure on the tragus.
文摘Objectives: Necrotizing external otitis(NEO) is a rare infectious disease of the skull base. The purpose of this study was to determine whether clinical outcomes of NEO can be correlated to different infectious spread patterns.Methods: Retrospective chart review from 2010 to 2019 with NEO patients, who were divided into two cohorts: single spreading patterns(group A) or complex spreading patterns(group B) as diagnosed by CT.Clinical symptoms, diagnostic and treatment delay, course of disease, complications, and duration of antibiotic exposure were retrospectively collected from patient records.Results: 41 NEO patients were included, of which 27 patients belonged to group A(66%). The diseaserelated mortality rate was 12.2% among the entire cohort, no differences were found between group A and B. Higher rates of N.VII(42.9% vs 14.8% P = 0.047) and N. IX palsies were found in group B compared to group A(28.6% vs 3.7%, P = 0.039). The median duration of antibiotic use was significantly different for a complex spreading pattern, clinical recovery and hospitalizations. Complications were associated with higher diagnostic delay and with a complex spread pattern. The median duration of follow-up was 12.0(IQR 6.0-19.5) months.Conclusion: NEO is a severe disease, with significant mortality and morbidity(cranial nerve palsies). The radiological spread pattern may assist in predicting clinical outcome. Furthermore, complex spread patterns are associated with higher rates of clinical nerve palsies(N. VII and N.IX), complications, surgery rates and longer duration of antibiotic use. Diagnostic delay was associated with mortality, complications and facial palsies.
文摘Objective To study the effects of Batroxobin on otitis media with effusion(OME), an early stage of Adhesive Otitis Media(AOM), for the purpose of expanding our understanding of the role of fibrinolysis in the pathogenesis of AOM. Method Forty cases of OME(45 ears) were randomly selected to receive intratympanic administration of Dexamethasone at 5 mg/ml(Group 1 or G1), Batroxobin at 1 BU/ml(Group 2 or G2) or Batroxobin at 2 BU/ml (Group 3 or G3). Pre-and post-treatment changes in clinical symptoms, the Air conduction Hearing Threshold (AHT) in pure tone audiometry and average AHT over 0.25 to 2 kHz were compared. Results Data from 31 cases(33 ears) were available for analysis. AHTs among three groups were similar prior to treatment(P > 0.05). The rate of normal hearing following treatment in G3 was 70% or 7 / 10, higher than in G1(41.7% or 5 / 12) and G2 (54.5% or 6 / 11)(P < 0.05). The rate of improvement following treatment was 81.8% or 9/11 and 80.0% or 8 / 10 in G2 and G3, respectively, higher than that in G1(50.0% or 6 / 12)(P < 0.05). Conclusions Therapeutic effects of intratympanic injection of Batroxobin on OME is superior to traditionally used Dexamethasone. In addition, higher concentration of Batroxobin appears to be superior to lower concentrations. These findings confirm that fibrinolysis plays a pivotal role in the pathogenesis of middle ear adhesion and that fibrinolytic medicine can prevent or reduce adhesion development in the middle ear.
文摘Otitis media with effusion(OME)is a frequent paediatric disorder.The condition is often asymptomatic,and so can easily be missed.However,OME can lead to hearing loss that impairs the child's language and behavioural development.The diagnosis is essentially clinical,and is based on otoscopy and(in some cases)tympanometry.Nasal endoscopy is only indicated in cases of unilateral OME or when obstructive adenoid hypertrophy is suspected.Otitis media with effusion is defined as the observation of middle-ear effusion at consultations three months apart.Hearing must be evaluated(using an age-appropriate audiometry technique)before and after treatment,so as not to miss another underlying cause of deafness(e.g.perception deafness).Craniofacial dysmorphism,respiratory allergy and gastro-oesophageal reflux all favour the development of OME.Although a certain number of medications(antibiotics,corticoids,antihistamines,mucokinetic agents,and nasal decongestants)can be used to treat OME,they are not reliably effective and rarely provide long-term relief.The benchmark treatment for OME is placement of tympanostomy tubes(TTs)and(in some cases)adjunct adenoidectomy.The TTs rapidly normalize hearing and effectively prevent the development of cholesteatoma in the middle ear.In contrast,TTs do not prevent progression towards tympanic atrophy or a retraction pocket.Adenoidectomy enhances the effectiveness of TTs.In children with adenoid hypertrophy,adenoidectomy is indicated before the age of 4 but can be performed later when OME is identified by nasal endoscopy.Children must be followed up until OME has disappeared completely,so that any complications are not missed.

文摘Objective: To report outcomes of balloon dilation Eustachian tuboplasty combined with tympanostomy tube insertion and middle ear pressure equalization therapy in treatment of recurrent secretory otitis media. Methods: Fifty one patients with recurrent secretory otitis media (62 ears) underwent balloon dilation of Eustachian tube and tympanic tube insertion under general anesthesia, followed by long term middle ear pressure equalization therapies. The Eustachian tube score (ETS) and Eustachian tube function questionnaire (ETDQ-7) were used for pre- and postoperative (up to 12 months) evaluation of Eustachian tube functions. Results: The mean ETS score was 2.34 ± 0.97 preoperatively, and 6.17 ± 1.54, 7.23 ± 1.62, 8.24 ± 1.97, and 7.63 ± 1.86 at 1, 3, 6 and 12 months postoperatively, respectively (P < 0.05). The ETDQ-7 score was 4.82 ± 1.07 preoperatively, and 2.20 ± 0.54, 2.32 ± 0.68, 2.53 ± 0.79, and 2.67 ± 0.76 at 1, 3, 6 and 12 months postoperatively, respectively (P < 0.05). Conclusion: Balloon dilation of Eustachian tube combined with tympanostomy and catheterization resulted in significant improvement of subjective symptoms and objective evaluation of Eustachian tube functions in most patients with recurrent secretory otitis media, as indicated by the ETS and ETDQ-7 scores, demonstrating high levels of efficacy and patient satisfaction.
文摘Objective: Clinical symptoms of otitis media with effusion are rarely brought forward to the guardians of young children who the disease is most prevalent in. This often leads to poor scholastic performances and difficult social interactions. The objective of this study was to identify asymptomatic cases of otitis media with effusion present in individuals with adenoid hypertrophy. Material and Methods: In a cross sectional study advocated in Justice K.S.Hegde Hospital, Karnataka India we evaluated one hundred patients above the age of three from August 2016 to December 2017. Candidates who presented with an adenoid nasopharyngeal ratio of more than 0.5 were selected for the study. Individuals who complained of otological symptoms were not considered for the study. Patients cleared of other pathological otological conditions were underwent audiological evaluation with pure tone audiometry and tympanometry for evaluating the middle ear status and hearing loss. Results: The study showed a total of 36% of patients evaluated presented with asymptomatic otitis media with effusion. In candidates who presented with a bilateral B tympanogram, 40% had significant conductive hearing loss of more than 25dB. Conclusion: An objective test such as impedance audiometry in all patients with adenoid hypertrophy would aid in the diagnosis of fluid in the middle ear, so that timely intervention can be done and possible complications be averted.
文摘Background:Malignant otitis externa is an inflammatory condition of the external ear which has the propensity to spread to the skull base.It can be a difficult entity to treat as clinical presentation varies and response to treatment differs between patients.We reviewed cases of malignant otitis externa in our setup to document the epidemiology and outcome of management.Methods:This is a retrospective case review observational study from January 2013eDecember 2017.Fourteen patients diagnosed with malignant otitis externa in our tertiary referral centre were included in the study.Based on hospital protocol,empiric treatment was started.After discharge,the patients follow up visits to the hospital were also documented.Results:Otalgia was the most common symptom.Edema and congestion of the external auditory canal were observed in most cases.Diabetes was present in all patients.Three cases had associated facial palsy,and one patient had involvement of 7th,9th,10th,11th and 12th cranial nerve.Two patients with facial palsy recovered.Pseudomonas aeuroginosa was the most common organism isolated(50%).Conclusions:In our series,malignant otitis externa invariably presented with severe otalgia.Lower cranial palsies were also seen.Methods to evaluate complete eradication of disease should be centered on clinical symptoms and signs,but the measurement of erythrocyte sedimentation rate or radiological imaging may be used as a useful adjunct when there is uncertainty.

文摘Otitis media （OM） is a middle ear infection associated with inflammation and pain. This disease frequently afflicts humans and is the major cause of hearing loss worldwide. OM continues to be one of the most challenging diseases in the medical field due to its diverse host targets and wide range of clinical manifestations. Substantial morbidity associated with OM is further exacerbated by high frequency of recurrent infections leading to chronic suppurative otitis media （CSOM）. Children have greater susceptibility to, and thus, suffer most frequently from OM, which can cause significant deterioration in quality of life. Genetic factors have been demonstrated, in large part by twin and family studies, to be key determinants of OM susceptibility. In this review, we summarize the current knowledge on immunity genes and selected variants that have been associated with predisposition to OM. In particular, polymorphisms in innate immunity and cytokine genes have been strongly linked with the risk of developing OM. Future studies employing state-of-the-art technologies, including next-generation sequencing （NGS）, will aid in the identification of novel genes associated with susceptibility to OM. This, in turn, will open up avenues for identifying high-risk individuals and designing novel therapeutic strategies based on precise targeting of these genes.
文摘Background:Patients with bilateral chronic otitis media-mucosal type have been conventionally treated with sequential tympanoplasty.Bilateral simultaneous tympanoplasty is usually not preferred because of the theoretical risk of iatrogenic sensorineural hearing loss.With the advent of modern surgical instruments and surgical techniques,the risk is expected to be lower.This study compares the clinical outcomes in typeⅠtympanoplasty performed simultaneously and sequentially.Materials&methods:This randomized prospective study was carried out in a tertiary care hospital between August 2015 and July 2017.A total of 30 patients were divided into two groups of 15 each.This study analyzed the graft uptake,pure tone audiogram findings pre-and post-operatively,duration of surgery and number of hospital visit for each patient and the outco mes were co mpared between both the groups.Result:Patients undergoing bilateral simultaneous tympanoplasty had significantly lesser mean duration of surgery and number of hospital visits than the patients undergoing sequential tympanoplasty.Graft uptake and postoperative wound infections were similar in both the groups.Postoperative hearing improvement was significantly better in the bilateral simultaneous tympanoplasty group.However,further studies are needed to authenticate this observation.None of the patients had a postoperative deterioration of hearing or sensorineural hearing loss.Conclusion:Bilateral simultaneous tympanoplasty is not only feasible but also better than sequential tympanoplasty,especially in terms of operating time,follow-up and overall financial implications on the patient.
文摘Background:Tuberculosis(TB)of the middle ear cleft(MEC)is a rare extra-pulmonary manifestation.Signs and symptoms of tuberculous otitis media are indistinguishable from that of non-tuberculous otitis media making early diagnosis difficult.Objectives:To study the clinical presentations,complications and effective diagnostic modalities in tuberculosis of middle ear cleft.Methods:We retrospectively studied 10 patients diagnosed with chronic otitis media,unresponsive to 2 months conventional treatment.Pure tone audiogram,High resolution computed tomography(HRCT)of temporal bone,and AFB staining of ear discharge were done.All patients underwent mastoid surgery.AFB staining and histopathological examination of granulation tissue removed from the middle ear and mastoid were also done.Results:Clinical findings were mastoid swelling,facial palsy and post-aural fistula 3,4&2 patients respectively.All patients had persistent ear discharge and three had vertigo.Hearing loss was of moderate conductive type in five,sensorineural type in three and mixed type in two.HRCT of temporal bone revealed soft tissue density in MEC in 9 and evidence of bone destruction in 6 cases.Diagnosis of TB was confirmed either by(a)demonstration of AFB in ear discharge(4 patients)/tissue removed during surgery(4 patients)or(b)by demonstration of tuberculous granulomas with necrosis on histopathological examination of tissue from MEC(8 patients).Conclusion:Tuberculosis should be suspected in all cases of chronic otitis media unresponsive to conventional treatment particularly in endemic areas.Histopathological examination and AFB staining of tissue removed during mastoid surgery are reliable diagnostic methods.

文摘Objective:To investigate surgical indications, operative techniques, complications and auditory and speech rehabilitation for cochlear implant (CI) in children with otitis media with effusion (OME). Material and methods:This is a retrospective review of records of 24children with bilateral profound sensorineural hearing loss and OME who were implanted during January 2011 to November 2014 in the Department of Otorhinolaryngology and Head and Neck Surgery at the PLA Hospital, using one-stage implantation via the facial recess approach and round window insertion. The incus was removed in 8 cases during the implantation procedure. Local infiltration of dexamethasone and adrenaline in the middle ear was also performed. Postoperative complications were examined. Preoperative and postoperative questionnaires including Categories of Auditory Performance (CAP), Speech Intelligibility Rating (SIR), and the Meaningful Auditory Integration Scale (MAIS) were collected. Results: All electrodes were implanted successfully without any immediate or delayed complications. Inflammatory changes of middle ear mucosa with effusion were noted in all implanted ears. The scores of post-implant CAP and SIR increased significantly in all 24 cases (t ? ?25.95 and ?14.09, respectively for CAP and SIR, p<0.05). Conclusions:One-stage CI via the facial recess approach with round window insertion is safe and effective in cochlear implant candidates with OME, as seen in the 24 children in our study who achieved improved auditory performance and speech intelligibility after CI.

文摘Tuberculous otitis media(TOM) is rare in ENT department,and is frequently misdiagnosed as otitis media.Thus early systemic treatment is very important for TOM.We reported a case report with TOM to highlight development of the disease and difficulties in clinical treatment in late stage of TOM.Implantation of ossified and eroded cochlea poses many unique challenges to both the surgeon and programming learn.With thorough preparation and complete knowledge about characters of specific issues,implantation would be performed successfully,and patients with ossified cochlear could benefit from cochlear implantation.
文摘BACKGROUND Acute otitis media(AOM)is a common disease that is more prevalent in children.Most studies concerning AOM-associated sudden sensorineural hearing loss are case reports and retrospective in nature,hence the etiology of AOM-associated sudden hearing loss has not been fully established.AIM To analyze audiological characteristics of AOM-associated sudden hearing loss and evaluate efficacy of combined tympanostomy tube placement(TTP)and intratympanic methylprednisolone.METHODS Eight adult patients who were diagnosed with AOM-associated sudden hearing loss and ineffectively treated by conventional medical therapy were enrolled in this study.Basic data were collected,and pure tone audiometry was performed to assess the audiological characteristics.Combination therapy with TTP and intratympanic methylprednisolone injection was given to the patients.RESULTS Mixed or sensorineural hearing loss was observed at high frequencies(2–4 kHz).All the cases in this study were cured after TTP and intratympanic methylprednisolone.After treatment,the average hearing threshold at affected frequencies was significantly lower than those in the pretreatment group(P<0.05)and was similar to that in the healthy ears(P>0.05).CONCLUSION AOM rarely induces sudden sensorineural hearing loss.Combination therapy with TTP and intratympanic methylprednisolone injection may be effective after failure of conventional medical treatment.
