Abstract
Objective: To assess the outcomes of intratympanic steroids in the management of idiopathic sudden sensorineural hearing loss. Study Design: Retrospective study. Setting: Academic tertiary care medical centre. Materials and Methods: A total of 67 patients with idiopathic sudden sensorineural hearing loss were included in our study. Pre- and post-injection audiograms were taken to assess the outcomes in improvement in hearing. Hearing outcomes were assessed with respect to duration of onset of treatment and age of the patient. Improvement in the speech discrimination score was also assessed. Results: A total of 67 patients were included in our study of which unilateral cases were 59 and bilateral cases were 8. Subjectively 35 patients reported improvement in hearing after the therapy while objectively we found 44 ears [41 patients] had improvement. The mean PTA pre ITS was 62.7 and after ITS it was 56.3. Maximum improvement was noted at 2000 Hz and 1000 Hz. Conclusion: Intratympanic steroids can be offered as a first line therapy for idiopathic sudden sensorineural hearing loss as it is minimally invasive, and can be performed as an office based procedure with no systemic side effects. No major complications have been reported in our study and results have been satisfactory.
Highlights
Idiopathic Sudden Sensorineural Hearing Loss [ISSHL] is an otologic emergency that requires quick and prompt management
To avoid the adverse effects and to have concentration of steroids in the inner ear intratympanic steroids are becoming the latest trend in the management of ISSHL
In our study we included 67 patients with ISSHL and all of them managed with intratympanic methyl prednisolone as the primary modality of management
Summary
Idiopathic Sudden Sensorineural Hearing Loss [ISSHL] is an otologic emergency that requires quick and prompt management. The term idiopathic should be applied only after ruling out other causes of sudden hearing loss like noise, trauma, infection, neoplasia, toxic, neurologic and metabolic causes [2]. ISSHL accounts for 1% of the cases of sensorineural hearing loss [3]. Silverstein first reported the use of intratympanic steroids in the management of sudden hearing loss [5] and since intratympanic steroids have gained popularity in the management of various disorders affecting the inner ear. To avoid the adverse effects and to have concentration of steroids in the inner ear intratympanic steroids are becoming the latest trend in the management of ISSHL. In our study we included 67 patients with ISSHL and all of them managed with intratympanic methyl prednisolone as the primary modality of management
