Background: Parotid neoplasm is a result of inadequate surgical incision during the treatment of head and neck cancers, and most of them are benign tumors. Hence, to explore a new surgical incision for parotid benign tumor in order to minimize the scar size on the premise of guaranteeing the safety of operation.Methods: We conducted a retrospective study of 48 patients who had undergone parotid surgeries from Jan. 01 2008 to Dec. 30 2014 at the department of otolaryngology, Jinshan Hospital of Fudan University. Histopathological examination confirmed benign parotid tumor (Warthin's tumor, pleomorphic adenoma, cysts, and monomorphic adenomas.) in all cases. All patients underwent a mini incision (cutting the skin directly on the surface of the tumor, and the incision was slightly longer than the diameter of the tumor). Results: Among the 48 cases, no recurrence and facial nerve injury were reported during the follow-up period of more than 4 years. Two cases of saliva fistula and one case of temporary facial nerve dysfunction were reported; however, they recovered quickly after symptomatic treatment.Conclusion: Extracapsular dissection is a safe and effective surgical procedure for the treatment of parotid benign tumor, and the postoperative scar is very small.
