People who experience a sudden hearing loss (SSNHL) are often treated with systemic steroids, which are taken orally. Studies however show that people with sudden sensorineural hearing loss (SSNHL) who do not respond to this treatment can benefit from intratympanic steroid injections. Studies carried out at universities in USA and Thailand show intratympanic steroid injections to be very effective and that the treatment does not have any side-effects.
Dr. David Haynes from Vanderbilt University Medical Center, Nashville, USA, carried out the study of 40 people who had experienced sudden sensorineural hearing loss (SSNHL). Overall, 40% showed some kind of improvement when treated with intratympanic steroid injections.
Destructive surgeries are irreversible and involve removing entire functionality of most, if not all, of the affected ear; as of 2013, there was almost no evidence with which to judge whether these surgeries are effective.  The inner ear itself can be surgically removed via labyrinthectomy, although hearing is always completely lost in the affected ear with this operation.  The surgeon can also cut the nerve to the balance portion of the inner ear in a vestibular neurectomy . Hearing is often mostly preserved; however, the surgery involves cutting open into the lining of the brain, and a hospital stay of a few days for monitoring would be required.
