Various Kinds of Issues Associated With Tinnitus | ArticlePDQ.com

The exact mechanisms of subjective tinnitus are largely unknown. A possible mechanism behind tinnitus is otoacoustic emissions. There are numerous microscopic hair cells with stereocilia lining the inner ear. These sound-sensing cells vibrate when they react to sound waves. Outer hair cells in the inner ear convert the vibrational signals into tension on the basement membrane. Both kinds of cells are connected through a neural feedback loop, that is usually adjusted just below onset of self-oscillation, giving the ear both selectivity and sensitivity. If the delicate balance is affected, the outcome could be tinnitus. Loud sound kills hair cells in the inner ear. As hair cells are destroyed, various neurons activate the brain?s auditory parts, producing the perception of noise, called otoacoustic emissions.

One more possible cause is damage to the receptor cells. It is thought that receptor cells in mammals can be produced only when the fetus is inside the womb. Therefore, if receptor cells are destroyed by exposure to extreme sound levels, the body cannot regenerate the cells and deafness to particular frequencies can be the outcome. Damaged receptor cells can wrongly relay information that an external noise is existing when it is not, producing tinnitus.

The most easily explained tinnitus is when indications are caused by trauma to the ear. Other obvious causes are more difficult to identify. It is believed that dental problems and temporomandibular joint disorder could cause tinnitus. There are two kinds of subjective tinnitus: somatic tinnitus and otic tinnitus. Otic tinnitus relates to the inner ear or the acoustic nerve, and somatic tinnitus relates to areas in the head and neck located outside the nerve and ear. There is speculation that somatic tinnitus results from ?crosstalk? between certain nerves of the head and neck when they enter the brain near parts which are involved in hearing.

Research has shown that overexcited auditory nerve cells in the brainstem could result in tinnitus. The majority of individuals that experience tinnitus have loss of hearing as well, and it has been noted that the subjective frequencies of their tinnitus is the same as the frequencies they could no longer hear. If this proves to be the mechanism behind some forms of tinnitus, the condition can be cured by medications which suppress or regulate overactive neural activity.

There are long-term treatments which deal with the level of an individual?s understanding of her or his tinnitus. Treatments concentrate on improving the general state of the nervous system. Recent studies concentrate on the use of cell phones and other electronic gadgets as likely causes of tinnitus.
