||Patients with second- or third-degree burns to the ear may be treated prophylactically with subperichondrial injections of antibiotics effective against Pseudomonas at six to eight different injection sites distributed over both anterior and posterior surfaces of the auricle. Compresses moistened with 0.5% silver nitrate solution are then applied. If, at a later date, perichondritis develops, the abscess should be incised and drained in the operating room and small catheters placed under the skin into the abscessed area. The catheters may then be irrigated with diluted solutions of antibiotics effective against Pseudomonas.
The hot liquid entered the external canal. The deep meatus is edematous and the attic area is both edematous and erythematous from the second-degree burn.
