ABSTRACT

Background: Otosclerosis classically manifests as a progressive sensorineural and conductive hearing loss that commonly affects both ears. It may be associated with vestibular symptoms but rarely with vertigo. Up to 90% of the affected patients report tinnitus during the course of the disease but it is not known in which proportion of cases it is disabling or even consists in the main reason for consultation; nor to what extent a stapedectomy modifies its evolution.
Objective: To correlate the state of presurgical chronic tinnitus in patients susceptible to be submitted to estapedectomy with the postsurgical state of the symptom to assess the role of the possible factors related to this surgery to the relieve of the postsurgical audiometric result.
Material and Method: A prospective, descriptive and crosssectional study was done including 198 candidates for primary stapes surgery and we selected those with disabling tinnitus according to their scores obtained in the Tinnitus Handicap Inventory (THI) questionnaire applied before and after surgery. Factors such as intensity of tinnitus, sex, age, pre and postoperative audiometric status, surgical technique, type of prosthesis used, among others, were analyzed.
Results: Out of 198 patients, 99 had presurgical tinnitus, with a mean age of 43.3 years. Disabling tinnitus had a directly proportional correlation with age and time of evolution of this symptom; it was more frequent in older than 40 years.
Conclusions: Primary stapedectomy has a positive impact on the reduction of disability caused by tinnitus in patients with otosclerosis.
