Hearing Loss
Key Points
Cerumen, genetic disorders, infections, aging, and noise exposure are the most common causes of hearing loss. All patients with hearing loss should have audiologic testing. Cranial nerve deficits and other neurologic deficits should raise concern and warrant imaging tests. Treatment modalities include correction of reversible causes, hearing aids, surgical procedures including ossicular reconstruction and cochlear implants, and various assistive technologies.
