Abstract
Three patients with intramuscular tumors of the masseter were surgically treated. Because intramuscular tumors of the masseter involve intramuscular variants of malignant tumors and lack of accurate preoperative diagnosis, external tumor excision with a margin surrounding of normal muscle appears to be the best surgical procedure for the tumor. The external subcutaneous approach is recommended for masseter tumors because of the advantages of shorter duration of surgery, excellent exposure of the tumor for excision, and visualization of facial nerve branches at the anterior edge of the gland without handing the parotid gland.
