掌握准确眶周组织解剖对于眶部重建手术的合理选择非常重要。但学者们对于外眦腱(lateral canthaltendon,LCY)的局部解剖仍有争议。作者选择21个保存完好的Caucasian尸体眶部组织,对每侧ICT骨性附着组织块进行组织学检查:①测量LCT附着中点至颧额缝的距离(ZFS-LCT);②外眦连合至外眶中点-LCT的水平宽度(LCT-Lo);③内眦与外眦附着垂直高度间的 To master the accurate periorbital tissue anatomy for the rational choice of orbital reconstruction surgery is very important. However, there is still controversy about the local anatomy of lateral canthaltendon (LCY) by scholars. The authors selected 21 well-preserved orbital tissues of Corpus Corpus, and histologically examined each of the ICT-attached tissue masses on each side: (1) measuring the distance from the midpoint of attachment of the LCT to the zygomatic zenith (ZFS-LCT); To the outer orbital midpoint - the horizontal width of LCT (LCT-Lo); ③ between 内 and 眦 attached vertical height
