sensorineural deafness
Quick Summary
Sensorineural deafness, also known as nerve deafness, is a hearing disorder resulting from damage to the inner ear's sensory cells or the vestibulocochlear nerve. This damage prevents sound impulses from being transmitted to the brain's auditory center.1
Causes of sensorineural deafness include:
* Injury to sensory cells, such as from excessive noise.1
* Viral infections like mumps, measles, or influenza.2
* Genetic defects affecting the cochlea.3
* Congenital conditions present at birth.13
This type of deafness is typically permanent and cannot be improved through medical or surgical treatments. Audiology is the study and treatment of hearing disorders, and pure-tone audiometry is a common method used to assess hearing sensitivity and diagnose the type and degree of hearing loss.124
