Sensorineural Hearing Loss
It is estimated that the annual incidence of sudden sensorineural hearing loss is 1 in 5000 people or about 4000 new cases per year in the US. 1
Sudden sensorineural hearing loss is defined as a rapid onset of hearing loss over a 72-hour period. It usually occurs in one ear and can be associated with other symptoms such as dizziness and ringing in the ear (tinnitus). It can affect people at any age, but it is most common in adults between 50-60 years of age.2 Sudden sensorineural hearing loss is a serious condition and should be treated as a medical emergency.
A comprehensive hearing test performed by an audiologist can help to diagnose sudden sensorineural hearing loss. In addition, a thorough work up performed by an Ear, Nose, and Throat physician is necessary. Further testing may include an MRI, blood tests, and balance tests.

How is Sudden Sensorineural Hearing Loss Treated?
Medical treatment should be obtained as soon as possible to better the prognosis of sudden sensorineural hearing loss. The most common treatment is a course of corticosteroids such as oral prednisone and/or intra-tympanic steroid injections. The majority of people with sudden sensorineural hearing loss will recover some degree of the loss and small percentage of people will have symptoms that worsen. 2,3
After treatment, if hearing loss remains, then hearing aids, implantable devices and/or assistive listening technology can help manage the residual hearing loss.
If you suspect that you may have sudden sensorineural hearing loss, seek medical help right away.
