Abstract
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).
Conclusion and significance: Compared with vein grafting, the reconstruction of parotid ductal defect with submandibular gland ductal graft has better long-term effects.

背景：本研究的目的是, 应用一种新的手术方法来保持颊癌患者的腮腺功能。该手术方法依据用颌下腺导管修复腮腺导管缺损。
目的：介绍自体颌下腺导管重建术治疗颊癌腮腺导管缺损的方法, 并评价其临床应用价值。
材料与方法：对28例颊癌患者行颊颈部联合根治术和带血管蒂皮瓣移植术。术后6个月复查修复导管的功能。
结果：两组均在术后1个月内取得良好的近期疗效。术后6个月的颌下腺导管造影检查显示, 颌下腺导管移植组有6%的患者出现阻塞或不畅。同时, 静脉移植组有45%的患者出现衰竭或梗阻, 疼痛VAS评分高于颌下腺导管移植组（p < 0.05）。
结论及意义：与静脉移植相比, 颌下腺导管移植修复腮腺导管缺损具有较好的远期效果。
