PY - 2022 T2 - Current Medical Diagnosis & Treatment 2022 AB - Earache can be caused by a variety of otologic problems, but external otitis and acute otitis media are the most common. Differentiation of the two should be apparent by pneumatic otoscopy. Pain out of proportion to the physical findings may be due to herpes zoster oticus, especially when vesicles appear in the ear canal or concha. Persistent pain and discharge from the ear suggest osteomyelitis of the skull base or cancer, and patients with these complaints should be referred for specialty evaluation.
