Posterior crus stapedectomy.

The results of stapedectomy were compared between 162 otosclerotic ears operated on using the posterior crus technique and 182 otosclerotic ears undergoing Teflon piston stapedectomy. The large fenestra technique with fascia seal to the oval window was used in all cases. Mean follow-up period was 9.6 years. Neither short-nor long-term hearing results showed any significant differences between the two surgical technique groups. Complications of surgery were more common in patients undergoing Teflon piston stapedectomy. On the other hand, a re-operation for recurring conductive deafness was performed significantly more often in patients undergoing posterior crus stapedectomy.
