title: High-pressure grease injury of the face.
abstract: We describe a rare case of high-pressure grease injury of the face in a 48-year-old man with severe facial edema, soft palate swelling, and bleeding from the nose and mouth. Preoperative computed tomography (CT) revealed multiple low-density areas in nasal cavity, subcutaneous tissue of the cheek, soft palate, right maxillary sinus, and right infratemporal fossa. The patient complained of a dyspnea feeling, and immediate tracheostomy was performed. The grease was removed by the Caldwell-Luc incision approach but was partially left in the infratemporal fossa. After the operation, the patient still complained cheek and temporal pain. CT and magnetic resonance imaging were useful to diagnose the remaining grease, and the remnant of the grease was completely removed by the Weber-Fergusson incision approach.
