What should I do about a scab behind the ear?
Crusting behind the ears can be managed through cleaning and disinfecting the affected area, avoiding scratching or irritation, identifying potential causes, providing localized symptomatic care, and monitoring changes in symptoms. In most cases, proper care leads to gradual healing. If crusting is accompanied by redness, swelling, pus, persistent pain, or recurrent ulceration, prompt medical attention is recommended.
1. Clean and disinfect the wound: Gently wipe around the crust with a sterile cotton swab dipped in normal saline to remove dirt and secretions. Then disinfect softly with iodophor, taking care not to rub too hard and cause bleeding or further damage. Keep the area clean and dry.
2. Avoid scratching and irritation: Itching may occur during the crusting process. Refrain from scratching or peeling off the scab with hands to prevent bacterial infection, worsened skin damage, and delayed healing. When necessary, cover the area appropriately to minimize contact.

3. Identify underlying causes: Check for possible triggers such as trauma, eczema, or folliculitis. Crusting after injury is part of the normal healing process, while crusting caused by eczema or inflammation requires targeted care. Avoid exposure to allergens or irritants.
4. Localized symptomatic care: For dry crusts, apply a small amount of non-irritating moisturizing cream to soften the scab. For inflammatory crusts, use mild anti-inflammatory ointments under medical guidance. Avoid using potent steroid medications without professional advice.
5. Monitor symptom changes: Keep track of the size, color of the crust, and whether there is discharge or odor. Gradual reduction in crust size without abnormal secretions indicates good healing. Seek timely intervention if the lesion expands or unusual symptoms develop.
Maintain cleanliness and dryness of the skin behind the ears in daily life. During hair washing, avoid prolonged soaking in dirty water. Wear loose, breathable clothing to reduce friction. Follow a light diet avoiding spicy and irritating foods, and maintain regular sleep patterns to enhance skin repair capacity.
