摘要
本研究用扫描电镜观察7例人尸体上下颌骨微血管铸型后,发现颌骨表面的粘骨膜有许多小动脉和微动脉穿过骨皮质进入骨髓参与颌骨供血,而颌骨有大量小静脉和众多毛细血管穿出骨组织汇入骨外的粘骨膜血管系统。这些动、静脉和毛细血管有多种多样排列方式。与长骨骨干相比,颌骨同粘骨膜之间有着更加丰富的血管交通。这便是正颌外科截骨术后,移动骨块仍能成活的重要解剖结构基础。
The vascular relationships between jaw bones and their surrounding soft tissues arestudied by observing microvascular resin casts with scanning electron microscopy.The co-mmunicating vessels between the hard and soft tissues are composed of arteries,veinsand capillaries,which are arranged in various manners.Because of these plenty of bloodvessel communications,the moved tooth-alveolar segments can survive without medullaryblood supply after orthognathic osteotomies.
