Objectives：There are many reports on attempts to minimize complications and recurrences of tumor by sev-eral techniques for benign parotid tumor resection. The purpose of our study is to find out meaning of proce-dure without identifying main trunk of facial nerve compared to conventional parotidectomy. Material and Methods：We classified 121 patients into two groups. Patients who were underwent superficial parotidectomy or partial superficial parotidectomy were included in idenitification group(IF group), and patients who were treated with conservative partial parotidectomy or extracapsular dissection without identification of main trunk of facial nerve were included in the non-identification group(NF group). We analyzed the location of tumor, op-eration time, mean drainage duration, complication, recurrence and cosmetic satisfaction in two groups. Re-sults：NF group has shorter operation time and mean drainage duration than IF group, however there is no sig-nificant difference in complication and recurrence between two surgical techniques. The Cosmetic satisfaction was similar between two groups. Conclusion：Limited parotidectomy without finding main trunk of facial nerve may be reliable option for benign parotid tumors because it has advantages such as less operation time and mean drainage duration without increasing in recurrence or complication rate.
