ear, nose, and throat disorders
External Otitis (Acute)
Key Points
Acute external otitis is usually bacterial (pseudomonal); fungal causes are less likely and cause more itching and less pain. Severe pain with pulling on the pinna suggests acute external otitis. Under close and direct visualization, gently remove infected debris from the canal with suction or dry cotton swabs. Do not irrigate the ear. For mild cases, applyacetic acidandhydrocortisonedrops. For more severe cases, debridement is critical along with topical antibiotics (use a wick if the canal is swollen); sometimes give systemic antibiotics.
