Describe Both Conductive and Sensorineural Hearing Loss and Why They

Question

Examlex · Accepted Answer

The Answer is Conductive hearing loss occurs when the bones of the middle ear are prevented from working properly. The most common cause is otitis media, which is when the middle ear becomes swollen and filled with mucus due to an infection. Otitis media typically resolves on its own after the body fights off the infection and the mucus is reabsorbed by the body, a process that might take up to several months. Otosclerosis, however, which is abnormal growth of the middle ear bones causing conductive hearing loss, will not naturally resolve on its own and requires surgery. Sensorineural hearing loss most commonly occurs inside the cochlea and can be due to damage to the auditory nerve fibers but more often is due to hair cells in the inner ear becoming damaged or destroyed. Drugs that are ototoxic can destroy hair cells directly, leading to sensorineural hearing loss. The most common source of damage to hair cells in the inner ear is from exposure to excessively noisy environments such as construction zones or extremely loud concerts. Hearing aids can help people to overcome sensorineural hearing loss by amplifying sound for frequencies that are severely impacted. Finally, cochlear implants may provide the ability to hear for people who are completely deaf due to a lack of hair cells in the cochlea.
