Evaluation and Management of Otalgia

Abstract

Otalgia can be broadly categorized into primary otologic causes and secondary nonotologic causes. Isolated otalgia in the absence of hearing loss, otorrhea, or abnormal otoscopic findings is typically secondary to referred pain from nonotologic causes, as the sensory nerve supply to the ear arises from 4 cranial nerves and the cervical plexus. The most common causes of primary otalgia are acute otitis media and otitis externa, whereas the most common causes of secondary otalgia are temporomandibular joint disorders and dental pathology. Persistent unilateral ear pain and other alarm symptoms warrant further evaluation for possible neoplasm.
