Abstract: PURPOSE: To explore the related factors of postoperative complications of parotid benign tumor. METHODS: The medical records of 215 cases with surgical treatment of parotid benign tumor were collected, the general data and different factors in surgical treatment and occurrence of postoperative complications were reviewed. SPSS 17.0 software package was used for data analysis. RESULTS: There was significant correlation (P＜0.05) between parotid gland fistula, facial nerve paralysis, Frey's syndrome and different factors (surgical incision， transfixion of residual parotid gland, method of facial nerve dissection, extent of resection, and employment of sternocleidomastoid flap). CONCLUSIONS: "N" shaped incision is not beneficial to routine drainage after operation, suction drainage was effective to decrease parotid gland fistula; the transfixion of residual parotid gland can avoid fistula after surgery; anterograde method for dissection of facial nerve and partial superficial parotidectomy can accelerate the speed of surgery and decrease the time of exposure of the facial nerve, which reduce the facial nerve paralysis; sternocleidomastoid flap is beneficial to avoid Frey's syndrome after surgery.
