Sudden sensorineural hearing loss (SSHL) is defined as a rapid- onset subjective sensation of hearing impairment, resulting in 30 dB loss at three or more frequencies .
The majority are unilateral hearing loss , and they may occur with tinnitus and vertigo or dizziness. The most effective treatment is oral and/or intra-tympanic injections of steroids. If a person presents for treatment within 2 weeks of the onset of symptoms, the chance of a full or partial recovery of hearing is much improved.
What to do!
1. See an audiologist for a hearing assessment ASAP to confirm diagnosis of sudden sensorineural hearing loss (SSHL) versus conductive loss.
2.See your GP/ ENT specialist to start on oral steroids, typically Prednisone .
3. Evaluate for retrocochlear pathology by MRI.
4. See an ENT specialist for intratympanic steroid therapy when incomplete recovery from sudden SNHL .
4. Follow-up audiometric evaluation at the conclusion of treatment.
5. Audiologic rehabilitation for patients who have residual hearing loss and/or tinnitus who may benefit from treatment.
