Background and Objectives : The aim of this study was to investigate the surgical outcomesof revision operation due to recurrence of non-cholesteatomatous chronic otitis media(COM) surgery cases.
Subjects and Method : From 1989 to 2018, 5197 cases of COM surgery were performed atKangdong and Hallym University Sacred Heart Hospital. Among them, clinical data of 297subjects who had undergone revision tympanoplasty and/or mastoidectomy for recurrent noncholesteatomatousCOM were retrospectively collected from computerized database of middleear surgery (Korean Otological Society program 2005). Each case was categorized by surgicalapproaches into canal wall down mastoidectomy (CWDM), canal wall up mastoidectomy(CWUM), or tympanoplasty only groups.
Results : Tympanoplasty only was performed in 170 cases, CWDM in 74 cases, and CMUMin 53 cases. Postoperative perforation occurred in 9.4% of total cases, and less frequently inCMDM compared with tympanoplasty only (p=0.023), and CMUM (p=0.049), respectively,whereas no differences between tympanoplasty only and CMUM (p=0.930) were found. Postoperativeinfection rate was 1.0% and did not show any differences among the groups. Postoperativesuccessful hearing was obtained in 66.7% of total cases, and the success rate of tympanoplastyonly was better than that of CMDM (p=0.001), and CMUM (p=0.011). And, that ofCMUM was better than that of CMDM (p=0.011).
Conclusion : The results showed that postoperative perforation occurred less frequently inCMDM than in tympanoplasty only and in CWUM; successful hearing was achieved morefrequently in tympanoplasty alone than in the other surgical approaches in recurrent non-cholesteatomatousCOM.
