A Prospective Study on the Outcome of Intratympanic Steroid Therapy in Patients with Idiopathic Sudden Sensorineural Hearing Loss
摘要
To study the outcome of intratympanic steroid therapy in the study group in terms of post-therapy hearing gain on pure tone audiometry. To study the complications encountered during and after therapy. A prospective observational study was conducted among 72 patients of 18–60 years of age presenting to the department of Otorhinolaryngology of a tertiary care hospital in India over a period of 3 years (June 2021 to May 2024), fulfilling the inclusion and exclusion criteria, to study the outcome of intratympanic steroid (Methylprednisolone, 125 mg/ml) therapy in terms of hearing recovery 1week and 1month post-therapy and complications encountered during and after therapy. 72 patients were included in the study (56% were males and 44% females), the mean age at enrolment being 49.7 years. Overall, 40 patients (55.56%) showed improvement in PTA while 30 (41.67%) had no change in hearing. According to Siegel’s criteria, 12 patients showed “complete recovery”, 22 showed “partial recovery” and 6 had “slight recovery”. 58.33% of patients presented within 72 h of onset of symptoms. Among these patients, 28.57% showed complete recovery, 33.33% and 14.29% showed partial and slight recovery respectively suggesting statistically significant correlation between hearing recovery and time of presentation (CI-95%, p < 0.005). The study suggested that intratympanic steroid therapy is an effective and safe treatment for idiopathic sudden sensorineural hearing loss with positive influence on hearing recovery with early initiation.
