Sensorineural deafness

About Sensorineural deafness:

• It is a type of hearing loss caused by damage to the inner ear or the nerve pathways that transmit sound from the ear to the brain.
• Although sensorineural hearing loss (SNHL) is a natural process of aeging, listening to very loud music can also cause permanent damage to the inner ear or the auditory nerve.
• Within the human inner ear, a spiral-shaped organ called the cochlea contains tiny hairs known as These hairs are responsible for converting vibrations from sound waves into neural signals, which your auditory nerve then transmits to your brain.
• Causes of Sensorineural deafness
  • Congenital Factors:Genetic factors or complications during pregnancy or childbirth.
  • Noise Exposure:Prolonged exposure to loud noise can damage inner ear hair cells, leading to noise-induced hearing loss.
  • Ageing:Natural ageing processes can damage or destroy hair cells in the inner ear.
  • Infections and Diseases:Conditions like meningitis, mumps, measles, and autoimmune diseases like Meniere's disease.
  • Trauma:Head injuries or inner ear trauma.
  • Ototoxic Medications:Certain antibiotics and chemotherapy drugs.
