Keep reading to find out what causes SNHL, how you can prevent it, and your treatment options if you’re currently dealing with it.Ĭonductive vs. SNHL isn’t a life threatening condition, but it can interfere with your ability to communicate if not properly managed. A loss of hearing between 41 to 55 decibels. A loss of hearing between 26 to 40 decibels. SNHL can range from mild hearing loss to complete hearing loss depending on the degree of damage. Eighty-five decibels is roughly equivalent to heavy traffic noise heard from inside a car. However, you might not experience hearing loss until 30 to 50 percent of these hairs are damaged. Exposure to sounds louder than 85 decibels can damage these hairs. These hairs convert vibrations from sound waves into neural signals that your auditory nerve carries to your brain. Nystagmus.A spiraling organ inside your inner ear called your cochlea contains tiny hairs known as stereocilia. Indian Journal of Otolaryngology and Head & Neck Surgery.

Review of congenital inner ear abnormalities on CT temporal bone. Neuroanatomy: cranial nerve 8 (vestibulocochlear). Though many medications can potentially trigger it, it’s most often associated with certain types of antibiotics, as well as some chemotherapy drugs. Ototoxicity: An unintended side effect of some drugs, otoxicity is characterized by hearing loss (when it affects the cochlear nerve) and severe dizziness (when it strikes the vestibular nerve).This condition is either due to an autoimmune disorder or as a result of viral infections, such as the West Nile and Zika. Symptoms are severe and include high fever, movement disorders, neck stiffness, sound and light sensitivity, and many others. Encephalitis: An inflammation of the brain tissues, encephalitis can cause serious dysfunction in the vestibular system.Some believe this condition arises due to autoimmune disorders or previous viral infections, while others speculate it has to do with constrictions in blood supply. Ménière's disease: Excessive fluid buildup in the labyrinth, of which the vestibular apparatus is a part, can result in severe vertigo, dizziness, tinnitus (ringing in the ears), and hearing loss.Exact causes of this condition are unknown however, it may be linked to viral infections, such as chickenpox, shingles, measles, hepatitis, and polio, among others. Vestibular neuritis: Inflammation of the vestibulocochlear nerve can lead to the onset of this condition, characterized by severe vertigo, spinning, dizziness, loss of balance, nausea, and vomiting.Nystagmus: This is a disorder of ocular motion, in which eye movements are jerky and unsteady they may be slow in one direction, but fast in the opposite direction and tend to “jump.” This may lead to problems with vision and dizziness. ![]()
