舌粘膜及粘膜下血管网的构筑及其临床意义

本研究应用手术显微镜和扫描电镜观察了人舌粘膜的微血管构筑。舌深动脉长支和舌背动脉终支在舌粘膜下形成一完整的致密动脉网,跨越界沟和舌正中线,成为一整体。由动脉网发出微动脉支进入舌粘膜内,形成粘膜内的毛细血管网和各种乳头毛细血管丛。另外,还讨论了舌粘膜下馓血管构筑和舌瓣设计与临床舌诊的关系。

THE ARCHITECTURE OF THE MUCOSAL AND SUBMUCOSAL MICRO-VASCULAR NET-WORK OF THE TONGUE AND ITS CLINICAL SIGNIFICANCE

The micro-vascular architecture of the mucosa and submucosa of human tongue was studied under the surgical microscope and scanning electron microscope. The long branches of the profunda lingual arteries and the terminal branches of the dorsal lingual arteries anastomose into a thick layer of arterial network, under the mucosa and over the superficial muscle of the whole body and root of the tongue. Arteriolae spring from the submucosal arterial network, which get into the mucosa to form the capillary network of mucosa and the 9apillary plexuses of variant papillae.The relationship between the architecture of the lingual submucosal arterial network and the design of flaps, and the clinical significance of tongue diagnostic signs has been discussed.
