Preservation of the facial nerve in the management of recurrent pleomorphic adenoma.
Whether to preserve or sacrifice a facial nerve involved with benign neoplasm is one of the most difficult intraoperative decisions confronting the head and neck surgeon. We reviewed 21 cases of recurrent pleomorphic adenoma treated with subtotal excision and facial nerve preservation, followed by postoperative radiation therapy. Of the 17 patients with microscopic residual tumor at completion of surgery, 16 (94%) remain free of recurrence with an average follow-up of 5.9 years. Only one of four patients (25%) with a large postoperative tumor load remains free of disease. Facial nerve function is normal in 20 of 21 patients. Preservation of the facial nerve with postoperative irradiation should be considered as an alternative to nerve sacrifice in selected cases of recurrent pleomorphic adenoma.
