Abstract | OBJECTIVES: Evaluation of the management of idiopathic sudden deafness indicating the usefulness of biological assessments and the pronostic factors of hearing recovery. PATIENTS AND METHODS: This is a retrospective study of 96 patients with idiopathic sudden deafness referred to a tertiary centre between 2005 and 2009 treated with corticosteroids intravenously at a daily dose of 1 mg/kg. Mean tonal thresholds were assessed (PTA = [500 Hz + 1000 Hz + 2000 Hz + 4000 Hz]/4). Each audiogram was classified as five classes according to its frequency profile. RESULTS: The hearing recovery is significant between D0-D5 and D5-M1 for the frequencies 0.5, 1 and 2 kHz. For 4 kHz, the recovery is significant between 0 and J5. There is no statistically significant correlation between the presence of associated signs ( tinnitus, vertigo) and hearing recovery. Hearing recovery according to the five types of audiograms has the same evolution in the follow-up time but with audiograms type E (cophosis or subcophosis) often associated with an hyporeactivity at the videonystagmography. The presence of cardiovascular disease is a predictor of poor hearing recovery. The usefullness of systematic extensive blood tests is low. CONCLUSION: In sudden deafness, the maximum hearing recovery takes place in the month following the onset of symptoms. The predictors of poor hearing recovery are an initial mean threshold > 70 dB, the existence of an associated cardiovascular disease.
