In 28% of cases, there was an improvement ofthe condition. Ofthese, in 18.7% there was a partial improvement, and in 9.3% a compiete recovery. There was no improvement in 72% of the cases. The relation between age and recovery was almost significant. A significant relation between improvement andright ear involvement was found. Conclusión. Most of our findings are similar to those reponed in the literature; the association between recovery an right ear involvement should be validated by Mure studies.
