Design:
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.
