![]() ![]() Individuals with damage to the auditory nerve are permanently deaf. ![]() Nausea and vomiting can also accompany the dizziness and episodes of vertigo resulting from auditory nerve damage. Falls are a risk with vertigo as you attempt to correct this miscommunication of being off balance. Vertigo is the false feeling that you or the room is spinning even though neither is true. Hearing loss may vary due to the type of damage and degree. Hearing loss usually accompanies damage to the auditory nerve. Though tinnitus is often described as ringing in the ears, other phantom noises can include clicking, whistling, roaring, or buzzing that occurs intermittently or constantly to various degrees. Symptoms include tinnitus, sensorineural hearing loss, dizziness, or vertigo with or without vomiting and nausea. Because damage occurs gradually, the cumulative effect of exposure to loud noises may not result in hearing loss until later in life.Įarly symptoms of auditory nerve damage may involve hearing or balance problems as the auditory system communicates information concerning sound and body positioning to the brain. Loud sounds damage the auditory nerve over time. Though rare, brain tumors can also lead to damage to the auditory nerve and permanent deafness. Auditory nerve damage can result from infection, disease, trauma, or medications. Though there are new research and developments for cochlear implants and other treatment, none fully restores hearing loss due to nerve deafness. Unfortunately, nerve deafness is generally permanent. Sensorineural hearing loss is deafness that happens when this nerve is damaged. This auditory nerve pathway carries sound and other information to the brain, which translates position and direction of sound origin as well as body position necessary to control balance. The second part of the auditory nerve is the auditory nerve also referred to as the vestibulocochlear nerve or the eighth cranial nerve. The cochlea located in the inner ear has tiny nerve cells responsible for transmitting sounds from the middle ear. The auditory nerve is composed of two parts. These cells convert the vibrations to nerve signals, which are then transported to the brain.The auditory nerve located within the inner ear is responsible for transmitting sound from the middle ear to the auditory centers in the brain. It is filled with fluid and lined with very fine hairs (hair cells). The sound waves are amplified by this transfer and then enter the cochlea. The malleus is attached to the eardrum, picking up its vibrations and passing them on to the inner ear via the incus and the stapes. It is the ear bones that are important for hearing: the malleus, the incus and the stapes. ![]() But germs can also enter the middle ear through the Eustachian tube from the upper throat. Air moves in and out to accommodate different pressures in the outside environment. It is connected to the upper throat by the Eustachian tube. The middle ear is an air-filled cavity also referred to as the tympanic cavity. First cartilage and then further on bone help to keep this passageway open so that the sound waves can reach the eardrum without being affected. Like a satellite dish, it captures sound waves and passes them on to the outer ear canal. ![]() The outer ear is made up of skin and cartilage. ![]()
