ABSTRACT

We describe a patient with a blood boil of the maxillary sinus that protruded through the alveolar ridge into the oral cavity. The patient was a 55-year-old man who visited our department because of a mass lesion in the left side of the maxilla. On X-ray film, the lesion occupied the left maxillary sinus, MRI findings suggested hemangioma. The lesion was diagnosed as heamangioma on biopsy. To prevent massive bleeding during surgery, selective embolization of the left maxillary artery and facial artery was performed 2 days before the operation. Consequently, the lesion could be resected safely. There have been no signs of recurrence. Since tha surgical specimen consisted of fibrin and blood components and showed no pathologic feature of hemangioma, the patient was given a definitive diagnosis of a blood boil of the maxillary sinus. Keywords: blood boil, maxillary sinus, selective embolization.
