PURPOSE
The present study aims to evaluate morphologic variations of the upper tarsus in Asians.
METHODS
Measurements of superior-inferior and medial-lateral lengths were performed on 54 embalmed cadavers. The superior-inferior length of the tarsus was measured at the central and lateral parts. On the basis of the measured values, shapes of the tarsi were evaluated and categorized.
RESULTS
The tarsi were classified into 3 morphologic categories-the sickle, triangular, and trapezoid types. The upper margins of the sickle, triangular, and trapezoid type tarsi present round, triangular, and flat lines, respectively. Among the 54 examined specimens, 29 (55.6%), 16 (29.6%), and 9 (16.7%) belonged to the sickle, triangular, and trapezoid groups, respectively.
CONCLUSIONS
The upper eyelid tarsi present morphologic variations with the Asian population. In performing surgical correction of blepharoptosis or surgical production of double-folds, this individual variation should be taken into consideration.
目的
本研究旨在评估亚洲人上睑板的形态变异。
方法
对54具防腐尸体进行上下径和内外径测量。睑板的上下径在中央和外侧部分进行测量。根据测量值，对睑板的形状进行评估和分类。
结果
睑板分为3种形态类型——镰刀型、三角形和梯形。镰刀型、三角形和梯形睑板的上缘分别呈圆形、三角形和平直线。在54个检查标本中，分别有29个（55.6%）、16个（29.6%）和9个（16.7%）属于镰刀型、三角形和梯形组。
结论
亚洲人群的上睑睑板存在形态变异。在进行上睑下垂手术矫正或双眼皮手术时，应考虑这种个体差异。
