Efficacy of surgical treatment of chronic otitis media.

摘要

This article presents our results of surgical treatment of chronic otitis media (COM) and discusses its efficacy regarding the control of disease and hearing results. A retrospective chart review of 84 ears was performed. Forty-one ears with noncholesteatomatous COM underwent tympanomastoidectomy, 43 ears with cholesteatoma were managed according to the extension of the disease, closed mastoidectomy was indicated in 19 cases, and open mastoidectomy was performed in 24 ears. In the group without cholesteatoma, a stable ear with closed tympanic membrane was obtained in 85% of cases after the first procedure. The speech response threshold before and after surgery was 38 and 26 dB. In patients with cholesteatoma, a dry ear was achieved in 79% of cases on both techniques after the first intervention. The recurrence rate of cholesteatoma was 10% for the closed technique and 4% for the open technique. The mean preoperative and postoperative SRTs for the closed technique were 30 and 29 dB and for the open technique were 50 and 54 dB. The surgical treatment for COM can be a rewarding procedure if a correct technique is indicated. The surgery should be tailored regarding the clinical stage and intraoperative findings in each case.
