Types of Hearing Loss:
Sensorineural hearing loss (SNHL) results from changes in the inner ear (cochlea) and the auditory nerve. Often, these changes cause permanent hearing loss that is not treatable with medicine or surgery. Some of the known causes of SNHL include the following: age, noise exposure, genetics, malformations of the inner ear, benign tumors, illnesses, medications known to be toxic to the ear, and injury/trauma. Hearing aids are a standard solution for hearing loss.
Conductive hearing loss (CHL) results from outer and middle ear changes. With a CHL, the sound is not able to travel (be conducted) efficiently down the ear canal, through the eardrum, and along the ossicles (middle ear bones). Some of the more common causes of CHL include the following: fluid in the middle ear, ear infection in either the outer and middle ear space, allergies, a hole in the eardrum, ear wax (cerumen) blockage, benign tumor, a foreign object in the ear canal, and the absence or malformation of the outer and middle ear.
Mixed hearing loss (MHL) results from the presence of both an SNHL and CHL at the same time. For example, a noise-induced SNHL may get a head cold that causes fluid in the middle ear.
