Differential diagnosis and treatment of hearing loss.

Hearing loss is a common problem that can occur at any age and makes verbal communication difficult. The ear is divided anatomically into three sections (external, middle, and inner), and pathology contributing to hearing loss may strike one or more sections. Hearing loss can be categorized as conductive, sensorineural, or both. Leading causes of conductive hearing loss include cerumen impaction, otitis media, and otosclerosis. Leading causes of sensorineural hearing loss include inherited disorders, noise exposure, and presbycusis. An understanding of the indications for medical management, surgical treatment, and amplification can help the family physician provide more effective care for these patients.
