PURPOSE
The aim of this study was to determine the width of the fibers that extend from the orbicularis oculi muscle (OOc) to the upper lip, and the lateral and inferior lengths of the OOc at the lateral canthus level.
METHODS
The OOc was investigated in the 40 hemifaces of 20 Korean cadavers. The lateral fibers of the OOc (OOc lat) were traced to determine whether or not these fibers extended to the upper lip.
RESULTS
The OOc lat extended to the upper lip at the lateral canthus level in 31 of the 40 specimens (77.5%), whereas some inferolateral fibers of the OOc that extended to the upper lip were observed near the level of the lower margin of the OOc in the other 9 specimens (22.5%). The mean ± SD and maximum widths of the OOc lat that extended to the upper lip at the lateral canthus level were 6.9 ± 3.3 mm and 14.3 mm, respectively.
CONCLUSION
The obtained data will be helpful to distinguish the muscles that underly the wrinkles around the lateral canthus for safer and more-efficient BoNT-A treatments for crow's feet.
目的
本研究旨在确定从眼轮匝肌（OOc）延伸至上唇的纤维宽度，以及在眼角外侧水平处OOc的外侧和下方长度。
方法
在20具韩国尸体的40个半侧面部中对OOc进行研究。追踪OOc的外侧纤维（OOc lat），以确定这些纤维是否延伸至上唇。
结果
在40个标本中的31个（77.5%）中，OOc lat在眼角外侧水平延伸至上唇，而在其他9个标本（22.5%）中，在OOc下缘水平附近观察到一些延伸至上唇的OOc下外侧纤维。在眼角外侧水平延伸至上唇的OOc lat的平均±标准差和最大宽度分别为6.9±3.3毫米和14.3毫米。
结论
所获得的数据将有助于区分眼角外侧皱纹下方的肌肉，以便更安全、更有效地进行肉毒杆菌毒素A治疗鱼尾纹。
