Sudden sensorineural hearing loss: Long-term follow-up results

Abstract

Objective 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. Study design and setting 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. Results 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. Conclusions 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. Ebm rating C-4.
