title: [Revision of stapedectomy (110 ears)].
abstract: We have carried out a retrospective study of 110 ears in patients affected with otosclerosis who underwent revision of stapedectomy, from 1979 to 1991, because they did not achieve hearing improvement or still presented persistent dizziness after primary stapedectomy. In our series, the most common causes of surgical failure after the first surgery are: displacement of the prosthesis (36.3%), ossicular chain alterations (21.8%) and regrowth of otosclerotic bone in the oval window (19.9%). One year after surgery, hearing test was compared with preoperatory tonal audiometry, finding and improvement in 48.1% (closure of 20 dB HL or more of the air-bone GAP), no changes in 43.6% and deterioration of the audition in 8.1%. Finally, we give some advises to prevent hearing loss in the revision of stapedectomy.
