Unilateral versus bilateral stapes surgery: A comparative study on auditory outcome and quality of life

Abstract

Otosclerosis is a well-known disease which mainly affects middle-aged female patients, causing conductive or mixed hearing loss. Diagnosis is essentially made through a complete audiometric battery testing, while treatment substantially relies on stapes surgery.In this study, we analyzed audiometric and Quality-of-Life data from 33 patients in order to refine the surgical indications (unilateral versus bilateral stapes surgery) and assess the best technique (stapedotomy versus partial stapedectomy) and timing of treatment. The original questionnaire OTOS, in the Italian language, was administered to all patients.In this study, most of the patients were female (18/33), with a mean age of 53 years old. Both surgical techniques appear to be effective with no significant difference in post-operative Air Bone Gap. OTOS questionnaire appeared to be effective in assessing quality of life in patients treated by stapes surgery. Post-operative QoL appeared to be similar in bilaterally and unilaterally operated patients, suggesting that a contralateral intervention after effective surgery should be undertaken only if expressly requested by the patient.
