Official Title: Quadrant Parotidectomy Versus Superficial Parotidectomy for Treatment of Pleomorphic Adenoma
Brief Summary: The most common benign tumor of the parotid gland is the so called pleomorphic adenoma. Although benign, this tumor may recur after surgical removal due to tumor cells left behind during the surgical operation. Thus, pleomorphic adenomas have been treated with wide resection similar to malignant tumors. This extensive surgery often leads to injury to the motor nerves responsible for facial expression and eye protection. The investigators propose less extensive surgery which should be thorough enough to prevent tumor recurrence while keeping the facial nerve out of risk.
