Comparative Study between Piezosurgery and Conventional Surgical Method in the Treatment of Otosclerosis

Abstract

Aim: This work aimed to compare Piezosurgery stapedotomy with the conventional approach in the managementof otosclerosis in terms of intraoperative time, postoperative complications, and air-bone gap improvement.Methods: This randomized controlled clinical trial was conducted in Beni-Suef University hospital from August2021 to June 2022 according to the ethical considerations of the local institutional review board. It included 40patients suffering from hearing loss due to otosclerosis, diagnosed based on clinical features, audiometry andimpedancemetry. Patients were randomly divided into two groups: group P underwent stapedotomy by thePiezosurgery medical device, and group C underwent stapedotomy by the conventional method.Results: Both groups were matched regarding their baseline characteristics. The air bone gap (ABG) postoperativelyreached a mean of 7.7±6.7 dB (median=6) in group P and 7.6±6.8 (median=7) dB in group C, with no significantdifference. The percentage of reduction of A-B gap was 76.21%±17.6% in group P (Piezosurgery), while group C(conventional) was 75.8% ±18.7%, with no significant difference. The operative time in group P was (35.5± 4.5)minutes vs (29.7 ±3.2) minutes in group C, with a significant difference. Regarding the complication, there was nosignificant difference between Piezosurgery and conventional surgery regarding intraoperative and postoperativecomplications (P-value > 0.05).Conclusion: This work concluded no difference between conventional techniques and Piezosurgery in (ABG)reduction postoperatively, intraoperative, and postoperative complications, only surgical time was longer inPiezosurgery group and was statistically significant.
