Abstract

Conclusion: The combination of systemic steroids with intratympanic dexamethasone injection (ITDI) did not result in significantly different outcomes from steroid treatment only and did not have any additional beneficial effects. Objective: To evaluate hearing recovery in idiopathic sudden sensorineural hearing loss (ISSNHL) according to frequency and to compare treatment responses between patients treated with systemic steroids and systemic steroids with ITDI. Methods: Ninety-nine patients with ISSNHL were selected to participate in the study by a retrospective medical chart review. Patients were divided into two groups, systemic steroid treatment only and systemic steroid with adjunctive ITDI. Hearing recovery was evaluated by pure tone audiometry (PTA). All patients underwent PTA examination before treatment and after 3 months. Thresholds were analyzed by frequency along with other factors. Results: Low frequency hearing loss responded better than high frequency loss to PTA. When we analyzed pure tone audiogram patterns, all patterns except for the descending type showed better improvement in patients with lower frequency hearing loss than in patients with higher frequency hearing loss.
