H60.319

Clinical Causes: Excess moisture in the ear canal, often from swimming or bathing Ear trauma from scratching or inserting objects like cotton swabs Allergic reactions to hair products, earplugs, or earrings Certain skin conditions such as dermatitis or eczema Bacterial or fungal infections—common pathogens include Pseudomonas aeruginosa and Staphylococcus aureus Prolonged use of hearing aids or hearing devices that trap moisture Narrow or abnormal ear canals that can trap water and debris

Key Symptoms: Itching in the ear canal Redness and swelling of the outer ear or ear canal Pain or discomfort, especially when touching or pulling the ear A feeling of fullness or blockage in the ear Drainage of clear, yellow, or pus-like fluid from the ear Decreased or muffled hearing Tenderness around the ear Sometimes, mild fever or general malaise if infection worsens

Diagnosis Path: Diagnosis of diffuse otitis externa involves a clinical examination by a healthcare professional. The practitioner will inspect the outer ear and ear canal using an otoscope to look for signs of inflammation, swelling, redness, discharge, or debris. They may also inquire about recent water exposure, activity history, and symptoms. In some cases, ear swabs or cultures may be taken to identify infectious agents, especially if the infection persists or recurs frequently. An assessment of the patient’s overall ear health, along with examination for any skin conditions affecting the canal, helps confirm the diagnosis.

Treatment Protocols: Cleaning the ear canal gently to remove discharge and debris Use of topical medications such as antibiotic or antifungal ear drops Application of eardrops containing corticosteroids to reduce inflammation Pain management with over-the-counter analgesics Keeping the ear dry—avoiding water exposure during healing Addressing underlying skin conditions or allergies that may contribute to inflammation In severe cases, oral antibiotics or antifungal medications may be prescribed
