Comparison of intermittent intratympanic steroid injection and near-continual transtympanic steroid perfusion as salvage treatments for sudden sensorineural hearing loss.

Objectives/hypothesis: The purpose of this study was to investigate whether near-continual transtympanic steroid perfusion is more effective than intermittent intratympanic steroid injection as a salvage therapy for idiopathic sudden sensorineural hearing loss.

Study Design: Case control study.

Methods: We designed a case-control study consisting of 60 patients with sudden sensorineural hearing loss who did not respond well to systemic steroid therapy.
