Many times those individuals, who inherited the disorder, otosclerosis, are plagued with tinnitus as well. Otosclerosis, the presence of extra bone in the inner ear, usually doesn't show up until late adolescence.
This disorder needs to be treated because it is progressive. If left untreated it eventually evolves in a deeper deafness due to the impairment of the transmission of sound vibrations.
It's very possible -- and indeed quite possible -- for an individual to have both otosclerosis and tinnitus at the same time, each having quite separate causes. If, though, the presence of the tinnitus is due to the overgrowth, the resulting noises are of low pitched.
The presence of a tumor -- and not necessarily a cancerous one -- may trigger the development of tinnitus. In fact one such tumor is called an acoustic neuroma, which very often causes tinnitus. The tumor occurs in the fibrous sheath covering the eighth cranial nerve. This is the one linking the inner ear with the brain.
If this is the cause of the noises in your head, you're probably experiencing vertigo at the same time. A branch of the nerve affected by the tumor carries signals from the organs of balance in the ear. As a rule, only one ear is affected.
The good news is the acoustic neuroma is removable through surgery. The bad news is the related tinnitus disappears in only approximately half of the cases.
Out Of Sync Thyroid
Your thyroid gland controls your metabolic rate through the release of a variety of essential hormones. A thyroid gland that refuses to function properly -- working too slowly or operating overtime -- may be the source of the ringing in your ears.
Diabetes, which may cause Meniere's Disease, can also cause tinnitus. This is the health condition in which the cells of your body cannot utilize glucose as a fuel due to a shortage of insulin. It is only now being discovered that an abnormally high number of diabetics also suffer with tinnitus.
Also known as disseminated sclerosis, this is a chronic disease of the central nervous system. It mainly affects young and middle-aged adults. MS damages the myelin sheaths which envelop the nerves in the brain and the spiral cord. Should the condition spread to affecting the nerves which link the brain and the ears, it may indeed be the source of ringing in the ears.
Meningitis is an inflammation of the connective tissue membranes lining the skull and vertebral canal. Usually the first indication of the swelling is the development of noises in the ear. Other symptoms of meningitis include a rigidity of muscles, severe headaches, and a poor appetite. In severe cases of this condition, many experience convulsions.
