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

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