[Own experience in stapes revision surgery--analysis of indications].

AIM: Analysis of indications for stapes revision surgery in patients qualified for the secondary procedure at the Otosurgery Dept. Medical University of Lodz.

MATERIAL AND

METHODS

25 cases of stapes revision surgery out of the 385 total treated surgically otosclerosis cases are discussed.

RESULTS

In group A (patients after total stapedectomy) the following indications for the secondary surgical procedure were observed: 12 cases--platinum wire prosthesis displacement with ossicular chain discontinuity; 3 cases--perichondrium or adipose tissue atrophy; 2 cases of incudo-stapedial joint luxation. Group B was composed of 8 patients after stapedotomy (teflon piston operation, 0.6 mm).

CONCLUSIONS

(1) The most common indication for the stapes revision surgery in patients after total stapedectomy were prosthesis displacement and necrosis of the long crus of the incus. (2) Obliteration of the stapes footplate after small fenestra operation was observed in our material to be the most frequent indication for the secondary stapes procedure.
