Neural Hearing Loss

Problems with the auditory nerve or the brain itself might become the reason of the neural hearing loss. The situation when it occurs is that when there are problems with the pathway from the cochlea to the brain. As you know that the neural means associated with nerve. Neural hearing loss takes place as the nerve that carries messages from the cochlea to the brain is missing or is not functioning appropriately. The main cause of this situation is the acoustic neuroma that is a benign tumor that develops on the vestibular nerve and then presses adjacent to your auditory nerve. If you notice the tumor soon enough and promptly have it removed you might be able to prevent any future hearing loss.

Another very significant method of testing for neural hearing loss is the acoustic reflex. The stapedius is a small muscle that is connected to the stapes and it contracts as a response to any loud noise. This contraction serves as a way of protection to the ear. The intensity of sound that is essential to activate this acoustic reflex can be typically used as a rough measure of your hearing sensitivity. If this is the situation that your middle ear is normal, then the deficiency of the acoustic reflex might point out that you have a type of neural hearing loss. On the other hand, the acoustic reflex would remain at normal levels even if you have rigorous cochlear hearing loss; however it generally disappears with mild neural hearing losses. This kind of hearing loss sometimes results in a bigger loss of speech discrimination than it does with sensory hearing loss. For the reason that damaged nerve fibers are not able to repair or redevelop themselves like some other parts of the body can, this kind of hearing damage is everlasting.

Predictable hearing aids do not actually help people who suffer from neural loss for the reason that the nerve is not able to convey the appropriate amount of information to the person's brain. A cochlear implant would not be able to help you also unless there is some type of auditory nerve task. In a number of situations of neural hearing loss, an auditory brain stem implant might help. Several possible reasons of neural hearing loss consist of heredity, experience to drugs, and too much noise, prenatal exposure to rubella, cytomegalovirus, and RH incompatibility at birth, low birth weight caused by untimely birth, high biliruben levels or jaundice, meningitis in addition to some kinds of infectious diseases for example the mumps.

Relying on accurately where the damage or oddity is to be found, symptoms might involve wispy, incomprehensible sounds or entirely no sounds at all. If the former condition is the case, the anomaly is not probable to be exclusively in contact with the auditory or VII cranial nerves or that severe. If no sound heard then this is a sign that the anomaly is located around or on the auditory and VII cranial nerves and is irreparably rigorous. In any case, some burning or fullness may be detected, if the reason is viral, bacterial, or disease or tumor oriented. Hearing loss or deafness in that ear is a main indication. As far as the treatments of neural hearing loss are concerned, they generally involve tests, like the Auditory Brainstem test, to find out exact where along the nerves the anomaly is to be found. Occasionally tumors can be removed, however in all other situations, no improvement can be made and hearing loss is everlasting. This is because of the reality that sound impulses can not go through the auditory nerve into the brain where they could be interpreted.
