An accessory parotid gland is located preauricular buccal area and it’s duct is separated from main duct of parotid gland. Tumours arised from accessory parotid gland is not so often, however, we experienced five cases with tumours considered to develope from the accessory parotid gland from 1996 to 2010. All tumours were performed the surgical removal under the general anaesthesia. The skin-incision lines were used the sigmoid-like temporal-preauricular-submandibular incision lines according to the peripheral technique for the conservation of facial nerves. Histopathological diagnoses were 3 pleomorphic adenomas, polymorphous low grade adenocarcinoma (PLGA), and carcinoma ex pleomorphic adenoma. No recurrence and minimum facial palsy was respectively remained under postoperative observation.
