Tympanoplasty Outcomes: A Review of 789 Cases

Introduction: Tympanoplasty is indicated to restore hearing disability and prevent recurrent otorrhea.  Materials and Methods: This study was a retrospective review of patients who underwent tympanoplasty with or without mastoidectomy over a 1-year period.  Results: A total of 789 tympanoplasties were reviewed, with a male-to-female ratio of 1:1.1. In total, 91% and 9% of tympanoplasties were performed without and with mastoidectomy, respectively. Complete graft take was observed in 98.6% of cases. Approximately 25% of patients had an air-bone gap (ABG) gap ≤20dB pre-operatively, increasing to 75.6% post-operatively. ABG closure improved from 0.8% to 46.7%. Mean ABG improved from 26.30 ±8.1dB pre-operatively to 14 ± 10.41dB post- operatively (t=28.7, P
