Sudden sensorineural hearing loss (SSNHL) develops over a period of hours or a few days and loss may be partial or complete. Though mostly unilateral, it may affect both ears. SUDDEN SNHL is defined as a hearing loss that should be a 30 dB sensorineural loss in at least 3 consecutive frequencies occurring over a period of 72 hours. The patient may have associated symptoms of tinnitus and a temporary spell of vertigo.
