Otosclerosis surgery.

Results of otosclerosis surgery using the stapes footplate removal with various types of reconstruction are reported in 456 ears (360 patients). Primary success was obtained in around 95% while 83% retained their improvement over the years. The posterior crus on fascia has become the preferred method because of its stability and relative lack of inner ear complications. Inner ear damage is mostly due to perilymph fistulae, which should be promptly recognized and repaired, since revision after the ear has become deaf does not restore hearing. Some late inner ear losses may be due to reactions to foreign material introduced with the graft. Bilateral operations should not be done if the first operation was difficult or caused vertigo for several days.
