Objectives: Injuries of neurologic structures during parotid surgery are sometimes unavoidable even in benign tumors. Since the major postoperative neurologic complications such as facial nerve palsy and Frey's syndrome give a serious and heavy burden to both patients and surgeons, it is very important to know detailed information concerning risk factors, the incidence of complication, possibility of recovery, and the term before complete recovery. Materials and Methods: This report was based on 95 patients with parotid gland tumor who had been treated and followed up over 1 year at department of surgery and otolaryngology, chonnam university hospital.
1) Among total 95 cases, the facial nerve palsy developed in 18 cases(l8.9%) and Frey's syndrome in 6 cases(6,3%). 2) The incidence of facial nerve palsy increased in cases with large tumor size, and in those operated with bipolar method. However, we didn't find out relationships between the incidence of facial palsy, localization, and histologic type. 3) The incidence of Frey's syndrome showed an increasing tendency in the cases with large tumor size, benign nature, and in those underwent superficial lobectomy with posterior approach, without a statistical significance.
Risk of facial nerve palsy, especially a transient form, seems to be related to tumor size and bipolar coagulation method. Although Frey's syndrome tends to develop easily in the cases treated with superficial lobectomy under the diagnosis of benign tumor, a futhermore study is suggested to obtain a statistical significance.
Key Words: Parotid gland tumor, Facial nerve palsy, Frey's syndrome
