Sensorineural Hearing Loss

Sensorineural hearing loss (SNHL) is the most frequent type of permanent hearing impairment resulting from injury to the inner ear or the auditory nerve pathways from the ear to the brain. It can develop slowly over time or quickly from infections, exposure to loud noise, head injury, genetic problems, or certain drugs. People with SNHL often have difficulty hearing speech well, particularly in busy surroundings, even when the noises are loud enough.

Symptoms include impaired hearing, trouble understanding conversations, ringing in the ears (tinnitus), disorientation, and a decreased capacity to hear high-frequency noises. The diagnosis is usually made with hearing tests such as audiometry, a physical exam, and sometimes imaging procedures to look for underlying reasons.

Even while damaged inner ear cells normally cannot regenerate, there are several therapy methods that can enhance hearing and quality of life. Mild to moderate cases are often treated with hearing aids, whereas cochlear implants may be beneficial for severe hearing loss. Speech therapy, auditory rehabilitation, and protection against loud noise are also an important part of the long-term care and prevention of future hearing damage.
