Many patients are not satisfied with their doctor’s answer when they complain about tinnitus. The proposed classification can be used to communicate with patients as well as guide future research. Type A itemizes the treatable causes of tinnitus. Type B itemizes tinnitus with a lack of medical explanation. Type C tinnitus is caused by diagnosable and treatable conditions, as listed in tinnitus type A, but the tinnitus persists after the successful treatment of the other symptoms.
