Oral steroid regimens for idiopathic sudden sensorineural hearing loss

Abstract

OBJECTIVE To determine hearing recovery in patients with idiopathic sudden hearing loss treated with varying amounts of oral steroids. STUDY DESIGN AND SETTING A retrospective chart review (n = 75) in a tertiary care clinic examined sudden hearing loss patients treated with 1 60-mg prednisone taper, 1 course of steroid less than a 60-mg taper, or any 2 courses of oral steroid. RESULTS: Overall, 35% of the patients recovered a clinically significant amount of hearing. Recovery was associated with immediate treatment (within 2 weeks from onset), better hearing at the onset of treatment, and treatment with the higher dose of prednisone in patients with just 1 additional symptom (dizziness or tinnitus). Patients tended to continue to experience some recovery in hearing up to 4 months after treatment. CONCLUSION: Immediate treatment of patients with unilateral idiopathic sudden hearing loss and additional symptoms (dizziness or tinnitus) with a 14-day course of 60 mg prednisone (with taper) is recommended. EBM rating: B-3.
