[Evolution of the operative technique. The rigid system stapedectomy].

In our Clinic, from 1987 up to 1993, 296 patients suffering from otosclerotic disease underwent stapedotomy, either using a classical or modified technique. The Authors reported the almost total disappearance of post-operative vertiginous symptomatology and a very good functional recovery; they believe that the placing of the prosthesis before disjointing the stapes, thereby allowing operation on a rigid structure, helps reduce labif1nthine traumatism. Moreover, stapedotomy with inversion of surgical times requires only a 24-hour hospitalization, with obvious advantages both for patient and clinic.
