CLINICAL EVALUATION OF 30 CASES OF PAROTID TUMORS

Abstract

Thirty resected cases of parotid tumor were retrospectively investigated about the treatments and postoperative complications. Postoperative facial nerve palsy was found in 6 out of 27 cases of benign tumor and in 3 out of 3 cases of malignant tumor. In these cases, facial nerve palsy turned to be permanent in 2 cases of each benign and malignant tumor. In other cases, facial nerve palsy disappeared in one month to 2 years. In one of malignant cases, facial nerve was resected in combination with parotid tumor invading the nerve and reconstructed successfully. Considering the postoperative complications and the radicality, ennucleation of the tumor is thought to be the most preferable method for the benign parotid tumor. In addition the nerve stimulator is thought to be useful for the preservation of facial nerve.
