作者对4~10个月胎龄的胎儿髁状突分别用显微解剖、微血管造影及组织学切片进行观察。结果显示：髁状突的血供主要来自关节囊颈部血管网，髓动脉和软骨膜内层血管网、营养支来源于面横动脉、嚼肌动脉、颞深后动脉、翼外肌动脉、颞浅动脉的关节后分支和鼓室前动脉的分支。髁状突血供呈立体交通系统，有明显的胎龄变化，在4个月（顶臀长度为107cm）时髁状突关节软骨中央有一条血管通道，并提出了血管通道形成之假设。
The authors observed fetal condyles of 4 to 10 months gestational age using microdissection, microvascular angiography and histological sections respectively. The results showed that the blood supply of the condyle mainly came from the vascular network of the neck, the medullary artery and the perichondrocytes in the articular capsule. The nutrient branches originated from the transverse transverse artery, the muscular chewing artery, the deep temporal artery, Posterior branch of superficial temporal artery and branch of tympanic artery. Condyle was presented as a three-dimensional traffic system with significant changes in gestational age with a vascular access at the center of the condylar articular cartilage at 4 months (107 cm top hip length) and the hypothesis of a vascular access was proposed.
