title: Improvement of bone conduction after stapes surgery in otosclerosis patients with mixed hearing loss depending from surgical technique.
abstract: This study investigate the effect of stapes surgery on bone conduction (BC) improvement in otosclerotic patients with mixed hearing loss and also compare the effect of three different types of surgery (complete stapedectomy, partial stapedectomy and microfenestration stapedotomy) on this improvement. We retrospectively reviewed surgical database of 84 otosclerotic patients with mixed hearing loss. Sixty-two patients (75%) had significant improvement in BC after surgery (P = 0.03). In 85% of patients with follow-up time longer than 1 year, this improvement had remained. Improvement in BC after surgery was better in partial stapedectomy group (82.6%) and complete stapedectomy group (80.8%) in comparison with microfenestration stapedotomy group (63%) (P = 0.052).
