However, only few patients will need a surgical reassessment. Objectives: To verify the incidence of surgical reassessment among adult patients;to verify the reasons that led the second surgery to be performed;to verify the efficacy—and audiological outcomes—of revisional surgery. Method: A longitudinal retrospective cohort study was carried out with the review of medical records, of adult patients, with bilateral severe to profound sensorineural hearing loss who underwent to revisional surgery, from 2004 to 2016 at a CI Center, in Brazil. Results: One hundred fifty-eight CI surgeries were performed among 137 adult patients. Fourteen revisional surgeries were performed among 10 patients: five surgeries were due by displacement of the internal unit;one because of having excessive subcutaneous tissue;one due to non-progression of the electrodes during the initial surgery, one late tympanic membrane perforation, one late facial palsy and, one due to a suture dehiscence in the surgical incision with exposure of the internal unit. Conclusions: The incidence of surgical reassessment among adult CI patients was 8.9%. All implanted patients that underwent a new surgical approach maintained an improved auditory threshold after revisional CI surgery.展开更多

Many studies suggest a negative relationship among duration of sound deprivation and audiometric gain (by means of speech perception test) after cochlear implantation. We evaluated surgical and audiologic results among post-lingual deafened adults, in different times of sound deprivation, and correlated with social isolation, presence of vertigo or tinnitus, and the speech therapy yield, between pre- and post-operative stages. A retrospective study was conducted on patients with post-lingual hearing loss, aged over 18 years old who underwent cochlear implant surgery in a public hospital from 2004 to 2014. Audiological, socio-demographic questionnaire, and manifestations of vertigo and tinnitus, during pre- and post-operative stages, were compared and correlating to the different periods of sound deprivation. Two groups were studied. The group A was composed of 38 participants (14 male and 24 female) with sound deprivation of less than 10 years;and group B was composed of 17 participants (8 male and 9 female) with sound deprivation longer than 10 years. We found no differences regarding age, sex, duration of sound deprivation, mean pure-tone audiometric results (pre- and post-surgery), and speech perception tests (pre-operatively). After one year of the surgery, we observed a significant difference between both groups, with a better performance to group A. The results of speech perception test, after cochlear implantation in group B, were worse than the results obtained in group A, although these correlations are not determinant whether to perform cochlear implant surgery or not.展开更多

The period from birth to 5 years of life is critical for the development of speech and language;therefore, there is need for early identification and assessment of hearing loss and early rehabilitation in infants and children. Cochlear implants are the treatment of choice for patients with severe to profound sensorineural hearing loss. The goal of the present study was to investigate the different hearing impairment etiologies of patients implanted in cochlear implant program. The hospital based interventional study was conducted in the Department of Otorhinolaryngology, SMS Medical College, Jaipur from July 2011 to Dec. 2013. Present study included 60 prelingually deafened patients who attended ENT OPD and underwent cochlear implant. The most common cause of deafness in our study was acquired (56.66%), which predominantly included perinatal risk factors (64.70%), followed by prenatal risk factors (41.17%). The second common cause was hereditary (26.66%), followed by unknown (16.66%). Infection and ototoxic drug history were the most common risk factors in prenatal and postnatal group. The most common perinatal cause was low birth weight and prematurity.展开更多

Design: Review of a medical chart from a patient with Arnold-Chiari syndrome that underwent to cochlear implant surgery. Case report: A 6 year-old female, with meningomyelocele and congenital hydrocephalus, deaf in the past 3 years, after meningitis. At that time, she used oral language with adequate speech development. Tone audiometry revealed bilateral profound sensorineural hearing loss. The MRI was compatible with the Arnold-Chiari syndrome. Cochlear implantation was performed on the left ear with MED-EL? Implant (model SONATATi100). Currently, the child is 12 year-old, performs speech therapy three times a week, with good hearing and language development. Conclusion: Despite the presence of Arnold-Chiari syndrome (Chiari type II) with neurological disorders and with ventriculoperitoneal shunt, patient had good hearing results after cochlear implant surgery.展开更多

Hearing loss is one of its leading manifestations, and surgery for removal of the tumor is often required. Cochlear implant (CI) surgery is an option for auditory rehabilitation and long latency auditory potentials (P300) are becoming a very useful tool to assess hearing outcomes. Objective: To verify the presence of P300 waves during auditory and cortical function assessment in a patient submitted to VS removal and CI surgery. Design: Retrospective chart review. Case Report: A 62 years old male patient, presented at the clinic with a bilateral severe to profound hearing loss, worst at the right side. MRI scan revealed bilateral expansive tumor within the internal auditory canal expanding to cerebellopontine angle, suggestive of VS. Tumor was removed at the right side, and CI surgery was indicated for the left ear. P300 tests were performed pre-operatively, at the moment of activation, and 6 months post-operatively. After CI activation, P300 waves appeared, and presented reduced latency and increased amplitude after 6 months of CI use. Conclusion: P300 waves appear to be dependent on the auditory stimulus to be generated, showing that it can be a useful tool to estimate improvement in cortical cognitive function after restoring hearing through CI surgery after VS removal.展开更多
