Sudden Sensorineural Hearing Loss; Prognostic Factors.

INTRODUCTION

Sudden sensorineural hearing loss (SSNHL) is a frightening and frustrating symptom for the patient as well as the physician. Prognosis is affected by multiple factors including duration of hearing loss, presence of associated vertigo and tinnitus, and co-morbidities such as hypertension and diabetes.

MATERIALS AND

METHODS

Forty subjects presenting to our department with features of sudden hearing loss were included in the study. Detailed otological history and examination, serial audiometric findings and course of disease were studied.

RESULTS

Subjects presenting late (in older age), having associated vertigo, hypertension and diabetes had a significantly lower rate of recovery.

CONCLUSION

Only 60-65% of patients experiencing SSNHL recover within a period of 1 month; this rate is further affected by presence of multiple prognostic indicators.
