Ear, Nose and Throat Disorders

Tinnitus

Tinnitus-the perception of sound in the absence of actual external sound-represents a symptom of an underlying condition rather than a single disease. Several theories have been proposed to explain the mechanisms underlying tinnitus. Tinnitus, the noise can be intermittent or continuous, and is very loud. Tinnitus is often associated with hearing loss, it does not cause the loss, nor does a hearing loss cause tinnitus. People with tinnitus experience no difficulty hearing, and in a few cases,  they even become so sensitive to sound that they must take steps to muffle or mask external noises. Prolonged exposure to loud sounds is the most common cause of tinnitus. Up to 90% of people with tinnitus have some level of noise-induced hearing loss. The noise causes permanent damage to the sound-sensitive cells of the cochlea, a spiral-shaped organ in the inner ear. A single exposure to a sudden extremely loud noise can also cause tinnitus. This track deals some of the most important topic which includes: Chronic sensorineural tinnitus, Tinnitus from sound exposure, Pharmacological treatment and Behavioral treatment, Electrical stimulation and vascular compression of the auditory nerve.
