N2 - OBJECTIVE: Sudden hearing loss (SHL) is a disease, isolated or associated with vertigo, of unknown etiology. The aim of this study was to identify the prognostic factors for hearing recovery.METHODS: In this retrospective study, we analyzed 287 cases of SHL (mean age 42). Tonal threshold audiometry, BAEP, and RM were the diagnostic procedures for clinical balance of the patient. The therapy used the following: corticosteroids, osmotic diuretic infusion, and vasoactives. All the factors were evaluated through statistical tests, Spearman test, and linear logistic regression.RESULTS: In our study, we observed that 39.3% of patients improved, 27.9% remained unchanged, 29% had complete recovery, and 3.8% worsened. Therapy was not related to the degree of recovery from hearing loss, whereas young age, delayed diagnosis, and audiometric curve type were the three factors related to the degree of hearing recovery.CONCLUSIONS: In our study, we report a better overall recovery rate compared with spontaneous recovery. In particular, early treated patients as well as patients with upsloping hearing loss frequently recovered after treatment. Age, time between onset and treatment, and audiogram type were shown to be significantly related to outcome.
