A retrospective study of audiological outcomes after endoscopic tympanoplasty and tympanomastoidectomy in patients with cholesteatoma

To investigated whether endoscopic tympanoplasty and tympanomastoidectomy could present satisfying audiological outcomes for cholesteatoma patients. This was a retrospective study of 83 patients with cholesteatoma who underwent endoscopic tympanoplasty and tympanomastoidectomy between 2019 and 2021. The preoperative and postoperative audiological evaluations were performed. The evaluation methods included air conduction (AC), bone conduction (BC), and air-bone gap (ABG) procedures. Eighty-three patients were included in the study, all of whom underwent endoscopic tympanoplasty and tympanomastoidectomy. Forty-seven patients presented postoperative ABG≤20 dB (59.49%). The frequencies tested included low-frequency (LF), middle-frequency (MF), high-frequency (HF), and pure-tone average (PTA). All three audiological parameters significantly decreased after surgery (P 0.05). There were also significant differences between the preoperative and postoperative proportions of degree of hearing (P
