title: Revision stapes surgery: a critical evaluation.
abstract: Fifty-six revision stapes surgeries performed during the last 9 years were evaluated retrospectively for their preoperative symptoms, intraoperative findings, and postoperative results according to the causes of failure, at the Gruppo Otologico, Piacenza, Italy. The most frequent causes of failure were found to be prosthetic misalignments, a reaction to the surgical trauma in the form of excess fibrous tissue reaction or new bony regrowth at the oval window, and ossicular chain problems. The location of the pathology was found to be an important factor in the outcome. Sixty percent of cases resulted in 0- to 20-dB air-bone gap. The causes of these failures, management, and their prevention during primary surgeries are also discussed.
