Disorders of the external ear.

External ear disorders are diffuse, varying from cosmetically unacceptable anomalies to serious neoplasms. Between these extremes lie the more common problems presenting to the primary care physician in an ambulatory setting. These problems include trauma, obstructions, dermatoses, and infections, some or all of which may be vexing to the busy clinician. Most of these problems are not serious and can be approached with the confidence of a salutary outcome with appropriate therapy.
