[Ossiculoplasty. Trial of comparison of different mountings].

Functional results of tympanoplasty are partly dependent on the ossiculoplasty phase. Based on results of 331 operations using the closed technique, statistical differences were evaluated between several classical ossicular buildings carried out essentially with homograft ossicles. The study involved assessment of postoperative audiograms practised under identical conditions, patients with anatomical failure being excluded. In type II cases, the different drum to stapes mountings tried gave better results than "malleus to stapes" mountings. In type III cases the difference was not significant. In all cases, results were significantly better when ossiculoplasty was performed during the second look.
