下颌骨透明标本的制作及其血供系统的观测

Observation of Blood Supplies System to Mandible in Transparent Specimen

目的探索下颌骨血供系统的直观观测手段。方法将6例墨汁灌注的新鲜下颌骨标本制作成透明标本,对其血供系统进行观察分析。结果下颌骨制作成透明标本后,可以清晰观测其血供系统的来源、分布以及吻合情况。下颌骨血供系统主要由下牙槽动脉及其分支,以及骨膜动脉网来完成。结论下颌骨透明标本是直观观测下颌骨血供的有效手段。

Objective To search for a direct observation met ho d in blood supplie system of mandible.Methods Six specimens of mandible were mad e transparent specimens after the vascular system was perfused with Chinese ink from the common carotid artery,and the blood supply system of mandible were obse rved and analyzed.Results The distribution of mandibular arteries was distinctly demonstrated in transparent specimens.The normal mandible receives its blood su p-ply from the inferior alveolar artery and the periosteal vessel meshwork.Conc lusion The transparent specimen is an ef-fective observation method in blood su pplie system of mandible.
