Current concepts in the clinical management of patients with tinnitus.

The current management in tinnitus of sensorineural origin is reviewed. Epidemiological data demonstrates that 90% of patients with hearing loss experience some tinnitus. Approximately 1% of the population suffer from a chronic tinnitus that causes severe distress and requires some type of management intervention. Present non-surgical therapies include masking techniques, psychological counseling, and biofeedback. There are also a number of drugs that have been applied, the most common being antidepressants. These have had the most success in managing patients with tinnitus, although it is currently felt that antidepressants treat underlying psychological problems rather than directly affect the tinnitus. The other large class of drugs include benzodiazopans, in addition to a new synthetic analog of a natural prostaglandin E1, misoprostol. Despite the many drugs now available, none has been approved by the United States Food and Drug Administration for the treatment of tinnitus. Many surgical therapies have been advocated but are directed towards the treatment of concurrent vertigo or for tumors of the cerebellopontine angle, with tinnitus sometimes being relieved by the operation. Specific surgical procedures such as cochlear resection and microvascular decompressions lack clear-cut efficacy. Despite author bias and a myriad of treatment modalities at present, there is still no specific therapy that definitively relieves tinnitus clinically.
