Purpose:
To evaluate short and long term results of stapes surgery in patients with osteogenesis imperfecta (OI), METHODS: Retrospective case series of 18 primary stapes surgeries performed on 11 hearing-impaired OI patients with evidence of stapes fixation, in a Tertiary referral center. We analysed pre-operative and post-operative hearing results at 1 month and at least 1 year RESULTS: The main operative findings were stapes fixation, thickened footplate and fragile or fractured stapes crura. No revision surgery was necessary. Hearing improvement was achieved in 94% of the cases. We obtained an air-bone gap closure to within 10 dB in 46% of the cases and to within 15 dB in 92% of the cases at 1-year follow-up. The mean hearing gain in air conduction (at 0.5, 1, 2 and 4 kHz) was 18.4 dB at 1 month and 22.4 dB at 1 year.
Conclusion:
Stapes surgery in OI gives good results with few complications in our series. A hearing gain is often obtained in spite of the sensorineural hearing loss caused by the natural progression of the disease.
