Sudden sensorineural hearing loss: long-term follow-up results.

Abstract

This study describes the long-term outcome of patients suffering from sudden sensorineural hearing loss (SSHL) after an initial combined therapy of steroids with vasodilators. Eighty cases were retrospectively reviewed to evaluate the long-term audiometric data and to statistically assess the value of specific clinical parameters. The persistent long-term otoneurologic manifestations associated with SSHL were also reported. In the long-term period, hearing level remained stable 2 months after the onset of SSHL. Patients complained of persistent tinnitus (36%), fluctuant hearing loss (8.7%), dizziness (8.7%), and classical Ménière's triad in 2.5% of cases. Profound and total SSHL associated with vertigo are poor prognostic indicators. In terms of cost-effectiveness, a steroid-vasodilator therapy for SSHL for >2 months is not recommended because no additional effect was evidenced. Persistent otoneurologic manifestations, mainly tinnitus or dizziness are relatively common, particularly in patients with severe to total SSHL. C-4.
