Sensorineural (sen-suh-ree-NUR-uhl) hearing loss, also known as SNHL, occurs because of damage to your inner ear. It can happen suddenly due to an illness, injury or exposure to loud noise, like an explosion. Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ (cochlea and associated structures), or the vestibulocochlear nerve (cranial nerve VIII).
Hearing loss can be broadly separated into two categories: conductive (problems in delivering sound to the inner ear) and sensorineural (problems of the inner ear, or cochlea, and/or the auditory nerve that connects the inner ear to the brain). Sensorineural hearing loss is a type of hearing loss affecting the inner ear or hearing nerve. It is different from conductive hearing loss, which affects the mechanical parts of hearing, such as the ear canal, ear drum, or middle ear. Sudden sensorineural hearing loss is defined as a rapid onset of hearing loss over a 72-hour period.
sensorineural hearing loss versus conductive hearing loss, It usually occurs in one ear and can be associated with other symptoms such as dizziness and ringing in the ear (tinnitus). What Is Sensorineural Hearing Loss? Sensorineural hearing loss occurs due to damage to the inner ear—specifically the cochlea—or the nerve pathways that transmit sound to the brain. Inside the cochlea are tiny hair cells responsible for converting sound vibrations into electrical signals. In this guide we’ll cover everything you need to know about sensorineural hearing loss, including signs to look for, how it’s diagnosed, and the treatment options available.
sensorineural hearing loss versus conductive hearing loss, This article provides a comprehensive review of the progress in the treatment and care of sensorineural hearing loss (SNHL), which is a common disease in the field of otolaryngology. Sensorineural hearing loss (SNHL) results from damage to cells or nerve fibers in the inner ear. It affects the auditory nerve, which carries sound signals to the brain. Overview Sensorineural hearing loss happens when there's damage to the inner ear or the hearing nerve that carries sound signals to your brain. Unlike other types of hearing problems that might be fixed with surgery, this type is usually permanent.
