We discuss the optimal treatment and outcomes pleomorphic adenoma of the salivary glands by reviewing the pertinent literature. Pleomorphic adenoma is the most common benign salivary gland neoplasm. It is found mostly in the parotid gland in middle-aged women. It progresses slowly and, left untreated, can produce significant morbidity and, rarely, death. The optimal treatment is superficial or total parotidectomy with facial nerve preservation, which results in local control rates of 95% or higher. Radiotherapy (RT) is useful to obtain local control in patients with positive margins, unresectable tumors, and multifocal recurrences after prior resection. Local control rates after RT for microscopic and gross residual tumor are approximately 80% to 85% and 40% to 60%, respectively. The main complication is surgically induced 7th nerve injury. Surgery is the mainstay of treatment and results in a very high cure rate. RT increases the likelihood of local control in the small subset of patients with incompletely resectable tumors and/or multifocal recurrences.
