[Reoperations in otosclerosis. Indications, intraoperative findings, and results]

The audiological outcome of 140 stapedectomy revisions done between 1977 and 1987, as well as the pre- and intraoperative findings and the subjective appraisal of the revisions, are presented. The recurrence of the conductive deafness was the most often indication for the surgical revision and the shift of the prosthesis, verified intraoperatively, the most encountered finding. Audiological results showed, as mean value, an important reduction of the transmissive hearing loss whilst the bone conduction remained unaltered. Patients' subjective evaluation of the results were worse than audiometric controls. From the retrospective study of these 140 revisions the AA' experience is that the stapedectomy revision offers no major risk for the inner ear.
