otitis externa
Pronunciation: oh-TIE-tis ex-TER-nah
Infection or inflammation of the external ear canal, commonly called swimmer's ear in pediatric patients.
Full Definition
Otitis externa is an inflammatory condition affecting the external auditory canal and auricle, frequently encountered in pediatric practice during summer months. The condition is often precipitated by water exposure, leading to maceration of the ear canal skin and subsequent bacterial or fungal infection. Clinical features include severe otalgia that worsens with manipulation of the auricle, purulent discharge, and canal edema. Treatment typically involves topical antimicrobial drops and pain management.
Usage
Usage note: Use 'otitis externa' in medical documentation; 'swimmer's ear' appropriate for patient communication.
