摘　　要：目的　了解成人下颌下腺微血管的构筑特点及分布规律,为下颌下腺减量移植提供解剖学依据。 方法　对摘除的正常下颌下腺进行墨汁、福尔马林灌注固定并切片,光镜下观察腺体的血管构筑的形态特点 和分布规律。结果　成人下颌下腺小叶内的纹管及腺泡周围血管网的血供主要来源于微前动脉,腺泡周围血 管网部分接受纹管周围血管网的供血,两个血管网有各自的静脉回流。在小叶内存在动—动,静—动,静—静 吻合;在小叶间导管存在动—动,静—静吻合。结论　下颌下腺的血管构筑特点为下颌下腺减量移植提供解 剖学依据,下颌下腺减量移植是可行的。Objective To explore the characteristics and distribution of adult submandibular gland microvasculature to provide the anatomic basis for substractive transplantation of submandibular gland.Methods The normal human submandibular gland was perfused by formalin and prepared chinese ink, its microvasculature was observed under the light microscope.Results Two types of the capillary network were found in human submandibular gland, which are the capillary plexuses around the acini and around the striated ducts, originated from the terminal arterioles. The anastomoses exist between the capillary plexuses around acini and around the striated ducts. The anastomoses between arteriole and arteriole, venula and venula, arteriole and vernula were seen in the lobule. And also, the anastomoses between arteriole and arteriole, venula and venula were observed in the interlobular ducts.Conclusion The present result provided the anatomic basis for substractive transplantation.
