Abstract
To clarify the effectiveness of stapes mobilization, the hearing level was investigated in 11 ears with otosclerosis before and after surgery. As a control, the hearing level before and after surgery was also investigated in 12 ears undergoing stapedectomy and 4 ears undergoing stapedotomy.
Significant hearing improvement was obtained at all frequencies after stapes mobilization and stapedotomy. Although significant hearing improvement was obtained at the low and middle frequencies after stapedectomy, hearing deteriorated significantly at high frequencies. These results suggest that stapes mobilization may be a useful surgical approach for otosclerosis.
