The purpose of this study was to investigate the clinical anatomy of the feeding artery of the submandibular gland (SMG). A total of 199 SMG removals were performed in extraoral or intraoral approach with/without endoscopic assistance by a single surgeon. The feeding artery of the SMG was always identified intraoperatively and recorded in the operation record. The clinical anatomy of the feeding artery of the SMG was investigated based on the intraoperative findings. The facial artery was ligated and transected for the involvement of tumor or severe inflammation in 16 (8.0%) procedures. The feeding artery was investigated in the remaining 183 procedures. The mean number of the glandular branch was 1.5. There were 1 branch in 98 procedures (53.6%), 2 branches in 80 procedures (43.7%), and 3 branches in 5 procedures (2.7%). Detailed anatomical knowledge of the feeding artery of the SMG is useful for proper dissection of the SMG and preservation of the facial artery.
本研究的目的是调查下颌下腺（SMG）供血动脉的临床解剖结构。由一名外科医生采用口外或口内入路，在有/无内镜辅助的情况下，共进行了199例下颌下腺切除术。术中始终识别出下颌下腺的供血动脉，并记录在手术记录中。根据术中发现对下颌下腺供血动脉的临床解剖结构进行了研究。在16例（8.0%）手术中，因肿瘤累及或严重炎症而结扎并切断了面动脉。在其余183例手术中对供血动脉进行了研究。腺支的平均数量为1.5支。98例手术（53.6%）中有1支腺支，80例手术（43.7%）中有2支腺支，5例手术（2.7%）中有3支腺支。下颌下腺供血动脉的详细解剖知识有助于正确解剖下颌下腺并保留面动脉。
