Time from sudden sensory neural hearing loss to treatment as a prognostic factor.

Introduction: The widely accepted treatment for sudden sensorineural hearing loss (SSNHL) is corticosteroid treatment (oral or intratympanic). The main goal of this work is to define the significance of the time between symptom onset and treatment initiation, as well as other prognostic factors, for hearing improvement.

Methods: This retrospective study included 666 patients treated for SSNHL.
