Chronic tinnitus is a frequent symptom in the current medical practice. Patients presenting with chronic tinnitus have to be evaluated by comprehensive examination, including ENT status, audiometry and complete neuro-otological evaluation if required, to exclude an organic cause of tinnitus, as an external--or middle ear lesion, or a retro-cochlear process. Most often, chronic tinnitus is only associated with a sensorineural hearing-loss. Overall, no drug treatment can be proposed. However, the patient needs help and two techniques can be proposed to make the symptom more tolerable: the bio-psycho-social model, with a medical and psychological sustain, and the habituation auditory therapy, using noisers to mask the tinnitus.
