Abstract

This article presents four cases of erectile hemangioma in the masseter muscle. These four patients, age 48 female, 18 male, 17male, 21 female, had same symptoms; enlargement of masseter portion follows muscle contraction. In all of cases, the swelling lesion took many years to become large. On the clinical examination, the swellings were immediately followed by masseter muscle contraction. The size and the hardness of the swelling gradually reduced during the patient kept contract on. In case 1 and case 2, the operations were performed after injecting silicon impression materials (for dental use) into the main cavities of hemangioma. This method makes it easier to resect the tumor. Case 3 was treated by extraoral approach and case 4 resected by intraoral approach. The pathological diagnosis of the first two cases were cavernous hemangioma and the last two cases were venous hemangioma. No patient had complications and recurrence.
