A retrospective review of medical records ws conducted in this study. Preoperative and postoperative evaluations included otoscopic examination and audiometric assessment. Furthermore, for patients with cholesteatomas, preoperative imaging was performed using temporal bone high-resolution computed tomography (HRCT). We recorded the surgical outcome, postoperative complications, preoperative and postoperative audiometric results, and surgical time in detail to carry out the comparison.
