A critical part of the evaluation will be a hearing test (audiogram) performed by an audiologist to determine the severity of your hearing loss, as well as whether it is conductive, sensorineural, or a combination of both. Once a diagnosis is made, your physician will be able to talk to you about all treatment options. This is important because the treatment for hearing loss depends on the cause. If you are experiencing hearing loss, you should see an ENT specialist who can make the correct diagnosis. Benign tumor-called “ vestibular schwannoma,” this is a noncancerous tumor on the adjacent balance nerve that compresses the hearing nerve that connects the inner ear to the brain, causing SNHL. ![]() Congenital inner ear malformation-genetic or environmental abnormalities (very common cause in children).Cochlear otosclerosis-abnormal bone growth in the inner ear.Central nervous disease-damage caused by a condition such as multiple sclerosis.Ménière’s disease-a condition characterized by fluctuating hearing loss, dizziness, ear fullness, or ringing in the ears (called tinnitus).Autoimmune inner ear disease-the body’s immune system attacks the inner ear and causes progressive hearing loss in both ears.Head trauma or abrupt changes in air pressure-this can cause the space that contains inner ear fluid to rupture.Acoustic trauma-exposure to loud noises (e.g., industrial/machinery or explosion/gunfire close to the ear can be prevented with proper protection).Aging-gradual SNHL that cannot be reversed (most common).Sudden hearing loss-may be caused by a virus you should see an ENT (ear, nose, and throat) specialist, or otolaryngologist, for urgent treatment that could help recover some hearing.Auditory nerve abnormalities will also cause SNHL. ![]() Sound energy reaches the cochlea, but damaged hair cells are unable to convert sound waves into neural signals that pass through the auditory nerve to the brain. Send us feedback about these examples.SNHL happens when there is damage to tiny hair cells in the cochlear and/or the auditory nerve. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'auditory nerve.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Andrew Grant, Discover Magazine, 27 June 2010 The signals from these cells are passed to the auditory nerve and decoded in the brain. 2021 In a sense, cyborgs already walk among us: Nearly 200,000 deaf or near-deaf people have cochlear implants, electronic sound-processing machines that stimulate the auditory nerve and link into the brain. Holly Barker, Discover Magazine, 3 Nov. 2010 Smoking can harm hearing in other ways, such as through alterations in auditory nerve signalling or by causing damage to the tiny hairs inside the ear. Carl Zimmer, Discover Magazine, 26 Oct. 2012 That is why tinnitus often doesn’t go away when people get their auditory nerve surgically cut. Jeremy Hillpot, Discover Magazine, This type of hearing loss, which affects many people, is currently untreatable it isn’t helped by hearing aids or cochlear implants, both of which depend on the auditory nerve to send the final signals to the brain. 2023 The electric charge stimulates the auditory nerve. Jennifer Ouellette, Ars Technica, 22 Mar. 2011 Beethoven-Haus Bonn An autopsy identified severe liver damage (evidence of cirrhosis) as the likely cause of death and significant dilation of the auditory nerve. ![]() Christopher Linstrom, Discover Magazine, 31 Jan. Recent Examples on the Web For the middle ear muscle reflex, the afferent limb is the auditory nerve the efferent limb is the facial nerve for the stapedius muscle and the trigeminal nerve for the tensor tympani muscle.
