RESUMEN
OBJECTIVES: This study aimed to investigate predictive factors for revision surgery in otosclerosis. METHODS: This was a retrospective, multicentre study in four tertiary centres. The primary objective was to investigate factors that were predictive of the need for revision stapes surgery. RESULTS: The 'revision' group included 145 patients, and the 'control' group included 143 patients. This study identified statistically significant predictive factors for the need for revision surgery: younger age, active smoking status, dyslipidaemia and high blood pressure. There was no statistically significant difference between the two groups in terms of surgical technique or stapedotomy technique. CONCLUSION: This study showed that patients who are candidates for primary stapes surgery with younger age, active smoking status, dyslipidaemia and high blood pressure are at higher risk of needing revision surgery. A holistic approach prior to stapes surgery with multidisciplinary assessment is recommended. These results are important for better patient counselling on expected outcomes and risks.
