Abstract：Objective To explore the value of endoscopic stapedotomy for treating otosclerosis patients.Methods The medical records of 22 patients who underwent endoscopic stapedotomy in the First Affiliated Hospital of Anhui Medical University between December 2017 and December 2019 were retrospectively analyzed. Patients included 9 males and 13 females, aged 13-70 (33.4±11.2) years old. The intraoperative situation and postoperative complications of the patients were reported. Postoperative complications such as vertigo, facial paralysis, and taste impairment were observed. The healing of the external auditory canal and tympanic membrane was observed 2 weeks after the operation. The mean preoperative and postoperative (3 months after operation) pure tone air conduction, bone conduction threshold, and air-bone gap of 0.5, 1, 2 and 4 KHz were compared to evaluate the audiological effect.Results Twenty-two patients with otosclerosis successfully underwent endoscopic stapedotomy for 50-145 (79.5±29.2) min. No cases of facial paralysis or sensorineural deafness were reported. Three cases of dysgeusia after the operation were relieved within 3 months, and five cases of dizziness were treated with medications. All cases were followed up for 4 months to 2 years, with an average of 14.5 months. The external ear canal incision healed well, with no external ear canal stenosis and no tympanic membrane perforation, two weeks after the operation. Postoperative hearing was evaluated 3 months after surgery. The air conduction threshold and air-bone gap were significantly reduced to (34.1±14.3), (11.5±7.8) dBHL, respectively. The differences were statistically significant (t=5.860, 8.407, all P values<0.01) compared with the preoperative (58.5±13.3), (34.8±10.4)dBHL. The difference between the postoperative bone conduction threshold (22.6±10.4) dBHL and the preoperative (23.7±8.3) dBHL was not statistically significant (P>0.05). No patients underwent revision surgery during follow-up.Conclusions Endoscopic stapedotomy for treating otosclerosis is an effective and feasible operation method, with the advantages of less trauma, wide and clear intraoperative exposure, low postoperative complication rate, and remarkable audiological effect.
