Abstract
Pleomorphic adenoma of the parotid gland is basiclly benign tumor . However, the reccurence of the tumor is sometimes found because of cell contamination . So the enucleation of the tumor is contra-indication, and we should perform lobectomy of the parotid gland. It is the most important technique to protect facial nerve in this operation . We often suffer from the bleeding of parotid gland because gland tissue is rich in blood vessels. So we usually use the radio knife to cut the gland tissue after protecting facial nerve with this technique and investigated the frequency of postoperative facial nerve paralysis. Though temporary facial paralysis was observed in 13 out 51 patients postoperatively, there was no permanent facial paralysis. All temporary paralyses were recoverd within 5 months.
