otitis externa
Inflammation of the outer ear canal, commonly known as swimmer's ear, frequently seen in children during summer months.
Full Definition
Otitis externa is an inflammatory condition affecting the external auditory canal, extending from the auricle to the tympanic membrane. In pediatric patients, it is commonly referred to as swimmer's ear due to its frequent association with water exposure that creates a moist environment conducive to bacterial or fungal growth. The condition presents with ear pain that worsens with manipulation of the auricle, itching, discharge, and sometimes hearing loss due to canal swelling. Risk factors include swimming, humid environments, trauma from cotton swabs, and underlying skin conditions like eczema. Treatment typically involves topical antibiotic or antifungal drops, pain management, and keeping the ear dry. Prevention education focuses on proper ear care and avoiding water retention in the ear canal.
Usage
