Background

The American Tinnitus Association estimates that over 50 million Americans experience tinnitus. Of these, about 12 million have tinnitus severe enough to seek medical attention. About 2 million persons in the US are so seriously debilitated by tinnitus that they cannot function on a "normal" day-to-day basis.

Tinnitus can be a relatively benign sound that is heard only occasionally, or it can be a devastating roar 24 hours a day, accompanied by hyperacusis (sounds are perceived as very loud) and sound distortion. The more severe tinnitus cases can be extremely debilitating, interfering with concentration and sleep.

There are many approaches to treating tinnitus, including drugs, masking devices and cognitive therapy; however, none have been proven effective in meaningfully alleviating symptoms. Drugs indicated for other conditions have been tried on tinnitus patients with poor results. Masking devices and behavioral training techniques (e.g., biofeedback and cognitive therapy) have had limited success in treatment of tinnitus. Masking devices produce low-level sound in an attempt to reduce the perception of tinnitus. Cognitive therapy is a type of counseling that attempts to treat a patient’s emotional reaction to tinnitus, rather than the tinnitus itself.

Recently, some researchers have shown that stimulating the auditory cortex to treat tinnitus symptoms has favorable results.** The Renova-TT™ Cortical Stimulation System* delivers targeted cortical stimulation to the auditory cortex to treat tinnitus.
