Post‐stapedotomy dizziness after applying topical steroid on footplate: A randomized controlled trial

Abstract

BackgroundOtosclerosis is characterized by abnormal bone growth in the otie capsule. Nowadays, stapedotomy is commonly used for otosclerosis treatment. Currently, postoperative dizziness has been associated with stapedotomy. In 1981, intratympanic dexamethasone was utilized to manage inner ear disorders like tinnitus and acute sensorineural hearing loss. However, there is much uncertainty regarding the effect and safety of topical steroid therapy in the middle ear during stapedotomy. In the present study, we assessed the effect of topical steroid therapy during stapedotomy on postoperative dizziness.MethodsOtosclerosis patients eligible for stapedotomy were randomly divided into two groups based on dexamethasone administration or placebo. Audiometric and tympanometry results were observed and recorded for the involved frequencies. The Dizziness Handicap Inventory was used to quantify patient perceptions of dizziness and balance issues. Audiometry and dizziness assessments were repeated at discharge and 4 months after the operation.ResultsThe study comprised 72 otosclerosis patients undergoing stapedotomy. At discharge, the intervention group showed a significant reduction in the incidence of dizziness compared to the placebo group. However, in the 4‐month follow‐up after the operation, both groups experienced a decrease in dizziness incidence, with no significant difference between them. There was also no significant difference in audiometric levels between the two groups. Interestingly, the intervention group had a significantly lower need for systemic anti‐dizziness drugs after surgery compared to the control group.ConclusionTopical dexamethasone during stapedotomy effectively minimizes dizziness at discharge and reduces the need for postoperative anti‐dizziness medication.Level of evidence2.
