A parotid duct is frequently cut and simply ligated in radical surgery for buccal mucosa carcinoma. We performed reconstruction of the salivary duct by microsurgical repair using a submandibular duct graft in a case of buccal mucosa carcinoma (T3N1MO). We made a bypass between the new orifice and the cut end of the parotid duct using a submandibular duct graft which was obtained by selective neck dissection (level I to II ). The defect after resection of the buccal mucosa was covered with the free radial forearm flap. The reconstructed submandibular duct graft collapsed after the postoperative radiotherapy. The function of the parotid gland could not be preserved ; however, this method was useful because the postoperative complications such as salivary fistula or swelling of the parotid gland could be avoided. This method is simple and minimally invasive. This method should be indicated in the case of N positive oral carcinoma in which parotid function is normal preoperatively. A case of parotid duct repair using a submandibular duct graft is reported.
