Sensorineural hearing loss (SNHL) occurs when the tiny hair cells (nerve endings) that detect sound in the ear are injured, diseased, do not work correctly, or have died. ; Conductive hearing loss, which means sound is not reaching the inner ear, usually due to an obstruction or trauma. It happens when the inner ear, hearing nerves, or hearing structures in the brain are damaged. It can be the result of illness or disease and usually builds gradually over time. Mixed hearing loss (a combination of sensorineural and conductive) Conductive hearing loss is less common and is caused by some form of blockage in the outer or middle ear. TMJ syndrome may cause ear pain, ringing in the ears (tinnitus), and hearing loss. Sensorineural hearing loss, unlike conductive hearing is usually permanent and caused by damage or malformation of the sensory hearing "hair cells" in the inner ear. There . A sensorineural hearing loss is a hearing loss due to damage to one of these two parts- either the inner ear (cochlea), or the nerve that sends sound from your ear to the brain (auditory nerve). Sudden deafness, also called sudden sensorineural hearing loss (SSHL) is a medical emergency. Sometimes it is difficult to determine and it also damaged by excessive noise.
