Abstract

OBJECTIVES

To investigate factors affecting the prognosis of sudden sensorineural hearing loss (SSNHL).

STUDY DESIGN AND SETTING

This is a retrospective study of patients with SSNHL hospitalized at an academic medical center. All patients in this study were treated with prednisolone and dextran. We compared a new 7-pattern classification for audiometric pattern and prognosis analysis with Sheehy classification.

RESULTS

We analyzed 148 affected ears in 146 patients. Occurrence of SSNHL was associated with changes in season. The best prognosis was with the midtone pattern of the 7-pattern classification and with the low-tone pattern of Sheehy classification. The older patients, those with vertigo, or those treated after 6 days had a poor prognosis. There was no significant association between ESR level and prognosis.

CONCLUSIONS

SSNHL patients with midtone loss have the best prognosis. This study of the audiometric patterns and prognostic factors of SSNHL allow us to better predict its outcome.
