Intra-Tympanic Dexamethasone Therapy via Grommet Insertion for Improved Auditory Outcome in Sudden Sensorineural Hearing Loss

AbstractIdiopathic sudden-sensorineural hearing loss (ISSHL) is an emergent otological condition needing prompt treatment for better recovery. In our study we aimed to determine the efficacy of intra-tympanic dexamethasone therapy after inserting a grommet in postero-inferior quadrant of the tympanic membrane for dexamethasone instillation. This is a prospective cohort study of 31 patients of ISSHL, in whom grommet was inserted and dexamethasone drops were instilled for 5  days. Several factors such as time of initiation of therapy, age of patient was considered, and inferences were drawn. Auditory outcomes were divided into low, mid and high frequency and the results were tabulated. Pairedt tested was applied for all frequencies for both pre-test and post-test.P-value was (<  0.05) in all the three ranges of frequencies. Also, statistical significance was found between early treatment from onset of disease and auditory outcome. The earlier the therapy was initiated, better were the results.
