Ear infections.

Infections of the ear are among the most frequent causes for patients to seek care in the ED. Although most infections are fairly simple to diagnose and treat, the anatomic complexity of the ear, its shared innervation with other body structures, its proximity to other body systems, and the risk of serious complications necessitate an orderly approach to the care of these problems. This article outlines an approach to the history, physical examination, diagnosis, and management of these infections. Adherence to such an approach should maximize the likelihood of attaining relief and obliteration of pain, prevention of acute and chronic sequelae, and ultimately, patient satisfaction.
