Abstract
Introduction. Sudden hearing loss (SHL) is a medical condition somewhat controversial in its etiology and treatment. There are few reports of SHL in the local literature. Aim. To assess the incidence of SHL at the University of Chile Hospital during a year-long period, analyzing the epidemiological, clinical and treatment characteristics. Material and Method. Restrospective review of SHL clinical data between December 2004 and November 2005. Results. Forty three patients diagnosed with SHL were included. Most were treated with corticoids. In 28% of cases, there was an improvement of the condition. Of these, in 18.7% there was a partial improvement, and in 9.3% a complete recovery. There was no improvement in 72% of the cases. The relation between age and recovery was almost significant. A significant relation between improvement and right ear involvement was found. Conclusion. Most of our findings are similar to those reported in the literature; the association between recovery an right ear involvement should be validated by future studies.
