Abstract

Objective : To evaluate short and long term results of stapes surgery in patients with Osteogenesis imperfecta (OI). Design: Retrospective case series. Setting: Tertiary referral center Patients: 18 primary stapes surgeries were performed in 11 hearing-impaired OI patients with evidence of stapes fixation. Intervention: Mainly CO2 laser stapedotomy with Teflon piston prosthesis. Main Outcome Measures: Pre-operative and post-operative audiograms at one month and at least one 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 15dB in 92% of the cases at one year follow up. The mean hearing gain in air conduction (at 0.5, 1, 2 and 4 kHz) was 18.4 dB at one month and 22.4 dB at one year. Conclusion: Stapes surgery in OI gives good results with few complication in our series. A hearing gain is often obtained in spite of the sensorineural hearing loss caused by the natural progression of the disease
