INTRODUCTION: In this study, we aimed to compare hearing results, cholesteatoma recurrence, and costs of one- versus two-session treatment in patients undergoing type IV tympanoplasty.
METHODS: Between June 2013 and August 2015, a total of 37 patients (20 females, 17 males; mean age 32.5±13.5 years; range, 20 to 48 years) who were operated for chronic otitis media with cholesteatoma were included. Hearing reconstruction was done in one session in 19 patients (Group 1) and in two sessions in 18 patients (Group 2). All patients underwent type IV tympanoplasty with closed cavity.
RESULTS: The mean age was 40.4±10.7 years and 26.5±12.4 years in Group 1 and Group 2, respectively. Recovery of hearing in Group 2 was significantly better than in Group 1 (p=0.001). The mean length of hospitalization was 6.8±2.6 days in Group 1 and 14.6±3.2 days in Group 2. In Group 1, cholesteatoma recurrence was found in two patients during diffusion-weighted magnetic resonance imaging. In the second-look operations, cholesteatoma recurrence was found in four patients in Group 2. Total cost of surgery and care was significantly higher in Group 2 than in Group 1 (p=0.001).
DISCUSSION AND CONCLUSION: According to our study results, two-session operation seems to be more beneficial with successful hearing restoration without additional costs.
