METHODS The degree of severity of the neoplasms was divided into 3 scores (i.e. 1 point for a slight degree, 2 points for a moderate and 3 points for a severe degree). The involvement of 22 respiratory and diges- tive sub-areas was evaluated and the total accumulative scoring and the scores for the lesions in the vocal area were calculated and sub - grouped. All the papillary epitheliomas were excised using a laryngeal micro-debrider or the micro laryngeal forceps under endoscopy-assist- ed suspension laryngoscopy. The differences between applications of the two modes of treatment for the cases of the groups with same scoring were compared as follows: the operation time, interval of operation, recent vocal quality after operation, postoperative scarring and incision of the trachea, as well as the distribution of tumors in a re-operation. RESULTS The 142 operative procedures were performed in 33 pediatric patients, with application of a laryngeal microdebrider in 14 cases and ex- cision in 19. Compared to the excision group (EG), the laryngeal mi- crodebrider group (MDG) displayed many superior features, such as a short operation time, long interval between operations, obvious improve- ment in vocal quality soon after operation, and a low frequency of subse- quent tumors. There was a significant difference between these modes of the operation. A postoperative incision of the trachea was required in 2 cases of EG, whereas no post-operation was needed in the MDG. CONCLUSION There are many advantages in using laryngeal micro-de- brider removal of JO -RRP. The procedure is simple and convenient, having a distinct operating field, precise incision, minor wounds, fewer complications and better vocal quality soon after operation, as well as quicker rehabilitation and longer intervals between operations, etc.展开更多

Study Design: This is a retrospective study. Setting: Tertiary referral centre. Subjects and Methods: All the patients diagnosed with laryngeal papillomatosis between January 2013 to December 2016 were included in this study. Preoperative assessment was done with rigid and flexible laryngoscopy. PRAAT software was used for voice analysis. All patients underwent coblation assisted microlaryngeal surgery. Post operatively patients were followed up at 1 week, 15 days, 1 month, 3 months and 6 months with rigid laryngoscopy. Voice analysis was repeated after 3 months to assess the improvement in voice. Results: Coblation was found to be effective in treating laryngeal papillomatosis. In our series of seven patients, three patients underwent repeat procedure with coblation for recurrence. But longterm follow up these patients did not reveal any recurrence of laryngeal papillomatosis. Voice analysis revealed a significant improvement in measures of perturbation and maximum phonation time. Conclusion: Coblation is a promising alternative to the conventional methods for the treatment of laryngeal papillomas as it can achieve satisfactory disease clearance with good voice quality.展开更多
