Preliminary application and evaluation of autograft reconstruction of parotid duct defect with submandibular gland duct for buccal cancer

摘要

Background: We aimed to preserve parotid function in patients with buccal carcinoma by applying a new surgical protocol based on reconstruction of parotid ductal defect with submandibular gland ductal. Aims/Objectives: The aim of this study is to introduce the method of autologous submandibular gland duct reconstruction for the treatment of parotid duct defect in buccal carcinoma, and to evaluate its clinical application in follow-up. Material and methods: A total of 28 patients with buccal carcinoma who underwent buccal and neck combined with radical surgery and vascularized flap transplantation were enrolled. Function of the reconstructed duct was reviewed in 6 months after surgery. Results: Both groups achieved good short-term results within 1 month after surgery. The 6-month postoperative angiography examination of the submandibular gland duct showed that 6% of patients in the submandibular gland duct graft group had a blockage or was not smooth. At the same time, 45% of the patients in the vein graft group had failure or obstruction, and the VAS score of pain was higher than that of the submandibular gland ductal graft group (p < .05).
