ABSTRACT
OBJECTIVE:
Our aim was to determine if stapes surgery is useful for treating inflammatory ear diseases. MATERIALS ANDMETHODS:
Thirteen patients underwent single-stage or staged surgery for stapes fixation due to tympanosclerosis alone or with cholesteatoma. Operative criteria were no tympanic membrane retraction, perforation or adhesion; middle-ear cavity with aeration >1 year; a fixed stapes. Computed tomography was used to analyse the relation between operative success and pre-operative pneumatisation.RESULTS:
Success rate at six months was 75 per cent. Hearing results were stable with little deterioration and no complications. Patients with poor pneumatisation had good results (with improved air-bone gap) only after staged surgery. Well-aerated ears heard better even with single-stage surgery.CONCLUSIONS:
Pre-operative computed tomography and intra-operative findings are necessary to determine the pneumatisation status of tympanic mastoid cavities. If criteria approved, poorly pneumatised patients underwent staged surgery. Stapedectomy achieved good hearing results for inflammatory middle-ear disease with stapes fixation.Palabras clave
