Introduction: The sudden deafness is a sudden loss of hearing at the neuro-senso-rial, for unknown reasons, and bad functional prognosis. The cause is unknown, generating multiple hypotheses and discussions on this topic. Aim: To evaluate the factors associated with prognosis and determine therapeutic aspects that influence the prognosis of these patients. Matherial and method: We reviewed the medical records ofpatients diagnosed with sudden hearing loss during a study period of 4 years, and calculate the frequencies of the different variables considered relevant; performed bivariate analysis and a comparison of the distributions byANOVA and a multivariate analysis with logistic regression and multiple lineal. Results: We analyzed 40 cases. We consider factors like the affected ear, cardiovascular history, hypertension, diabetes, dyslipidemia, snuff, hemoglobin, hematocrit, temporal and geographical, of which none were significant for recovery. After analysis of other factors, we found a predominance of cases in summer and autumn (90%%) compared to winter and spring (10%). Use of famciclovir was associated with greater likelihood of complete recovery OR 21.164 [1.265 to 374.47]. On the contrary, were linked to a lower linked to a lower likelihood of full recovery: treatment with hyperbaric OR 0.013 [0.0010.0433] OR descending audiometric curve [0.164 0.032 to 0.533] and the presence of vertigo associated with tinnitus OR o.158 [0.08 to 1.015]. Aspirin improved recovery of 24.3 db decibel half 95% CI [1.00 to 47.61]. Conclusions: The study is a retrospective multivariate analysis which shows that famciclovir and aspirin have a statisfically beneficial in the treatment of sudden deafness, which in our sample is more frequent in summer and autumn. Biased studies are needed on these results may provide new hypotheses for treatment.
