The aim of this article is to describe anatomical detail of the course and territory of the horizontal branch of the supraorbital nerve, which connects with temporal branch of the facial nerve. Eighteen hemifaces of Korean cadavers (11 male, 7 female) fixed in 10% formaldehyde solution were dissected. All 18 specimens had horizontal branch of the supraorbital nerve. The horizontal branch emerges out of the supraorbital foramen, runs upward about 12 mm, and then turns laterally at an angle of 104.7 degrees toward the end of the eyebrow. The average number of horizontal branches was 1.7 +/- 0.8. The skin boundary supplied by the horizontal branch was a circle with a diameter of 30 mm. The center was located at 30 mm lateral to the supraorbital foramen and 12 mm above. Grossly, the horizontal branch of the supraorbital nerve connected with the temporal branch of the facial nerve in 8 of 18 (44%) specimens. Microscopically, both nerve branches had common epineurium, but the perineuria were separated. The horizontal branch of the supraorbital nerve is in touch with the temporal branch of the facial nerve, and there are actual connections between them in 44% of cases.
本文旨在描述与面神经颞支相连的眶上神经水平支的走行及分布区域的解剖学细节。对18例用10%甲醛溶液固定的韩国尸体半侧面部（11例男性，7例女性）进行了解剖。所有18个标本均有眶上神经水平支。眶上神经水平支自眶上孔穿出，向上走行约12 mm，然后以104.7度角向眉梢外侧转折。水平支的平均数量为1.7±0.8条。水平支所支配的皮肤范围是以眶上孔外侧30 mm、上方12 mm处为中心、直径30 mm的圆形区域。大体观察，18个标本中有8个（44%）的眶上神经水平支与面神经颞支相连。显微镜下观察，两支神经有共同的神经外膜，但神经束膜分离。眶上神经水平支与面神经颞支相接触，在44%的病例中二者之间存在实际连接。
