Abstract

Accessory parotid gland tumors are defined as masses within salivary gland tissue located adjacent to Stensen's duct, but separate from the main body of the parotid gland. These tumors usually present as asymptomatic cheek masses. There is a temptation to excise these masses locally; however, the likelihood of injury to branches of the facial nerve is high. The best surgical approach to tumors in the accessory parotid region is via a standard parotid incision and concomitant superficial parotidectomy. Eight patients have been surgically treated with accessory parotid gland masses. Six patients had mixed tumors, one had a low grade mucoepidermoid carcinoma, and one had a localized parotitis. Our approach included a standard parotid incision, raising an anterior flap beyond the mass, and exposing the main trunk of the facial nerve, with careful tracing of all its branches. This approach to accessory parotid gland tumors is superior in that it provides a better margin of resection and minimizes functional and cosmetic deformities. Most importantly, there is less danger of injury to branches of the facial nerve.
