Abstract

Sudden Sensorineural Hearing Loss (ISSNHL) is sudden hearing loss, greater than 30 dB in 3 consecutive frequencies, can be accompanied by tinnitus and sometimes vertigo. The highest incidence occurs from the age of 45 between 55 and 65 years. Its etiology is unknown, but there are several hypotheses such as viral, immunoallergic and vascular causes. Its diagnosis should be made in the shortest possible time in order to guide the etiopathogenic possibilities and start treatment as soon as possible. The injection of intratympanic corticosteroids is the treatment of choice in order to achieve the recovery of hearing thresholds.
