Sudden Hearing Loss

Sudden Sensorineural Hearing Loss is a Medical Emergency :

What is it?
A typical patient loses his or her hearing in one ear over a period of one to several days, associated with a feeling of fullness in the ear, and often tinnitus, or ringing of the involved ear.

There may be dizziness or vertigo. Occasionally, the patient may report an upper respiratory infection (cold symptoms) prior to the onset of the hearing loss.

What should one do for sudden hearing loss?

Unfortunately, many patients delay seeking care by a specialist. The symptoms of decreased hearing and fullness of the ear are often diagnosed as a middle ear infection (otitis media) and so the referral to an audiologist or otolaryngologist (ENT specialist) is made too late. Or insurance issues may prevent referral in a timely fashion to an ear specialist.

A delay in treating this condition (2 weeks or more after the symptoms first began) will decrease the chance that medications might help improve the hearing loss.

How is sudden sensorineural hearing loss diagnosed?

The diagnosis can only be made by specialized hearing testing in a sound-proof chamber by an audiologist. Pure-tone thresholds, speech discrimination scores, acoustic reflex testing, and distortion product otoacoustic emission testing, the parts of a complete audiometric evaluation, are performed to confirm the diagnosis of a sudden sensorineural hearing loss.

A comprehensive evaluation by an otolaryngologist (ENT) and an audiologist will ensure that the loss is nerve-related, and not due to fluid, infection, or a perforation, or hole in the ear drum.

An MRI scan of the brain, with gadolinium contrast, is also performed to exclude the presence of a cerebellopontine angle tumor, such as a vestibular schwannoma (acoustic neuroma).

How is sudden sensorineural hearing loss treated?

If you do have sudden sensorineural hearing loss, treatment with steroids within the first 2 weeks of the symptoms provides the best chance that some of the hearing may return. The gold standard therapy is steroids by mouth but several small studies have suggested that steroids injected into the ear may be beneficial.
