Anatomic variability and anastomosis of the angular artery of the facial artery with the other arteries are important for both anatomists and surgeons. In particular, the angular artery is a significant landmark in dacryocystorhinostomy. Because of variations on anatomy of the angular artery, there are limited numbers of anatomic studies on the flaps of facial region. Hence, the aim of the cadaveric study was to evaluate the anatomic features of the angular artery in detail to help surgical procedures.

The artery was represented under x4 loop magnification in 32 sides of 16 formalin-fixed adult cadavers. The angular artery’s position, diameter, and branch patterns relevant to the nose arterial supply were evaluated. The facial artery ended symmetrically in 10 (62.5%) of the cadavers. The facial artery was terminated as angular artery in all of the cases. The types of the angular artery were as follows: classical angular type in 8 cases (25.0%), nasal type in 15 cases (46.9%), alar type in 4 cases (12.5%), and labial type in 5 cases (15.6%) on the facial halves. We studied the topographic anatomic features of the angular artery for increasing reliability of the flaps on the region. The angular arterial anatomic details are critical and essential for surgical cosmetic and functional results.

面动脉角动脉的解剖变异和与其他动脉的吻合对解剖学家和外科医生都很重要。特别是，角动脉在泪囊鼻腔吻合术中是一个重要的标志。由于角动脉解剖的多样性，对面区皮瓣的解剖学研究有限。因此，身体研究的目的是详细评估角动脉的解剖学特征，以指导外科手术。

在16具福尔马林固定的成人身体32侧的x4环状放大下显示动脉。评估与鼻动脉供应相关的角动脉的位置、直径和分支模式。10例(62.5%)面动脉终止对称。面动脉均终止为角动脉。角动脉类型：经典型角型8例(25.0%)，鼻型15例(46.9%)，翼型4例(12.5%)，唇型5例(15.6%)。为了提高该区域皮瓣的可靠性，我们对角动脉的解剖特征进行了研究。角度动脉的解剖细节对于外科美容和功能效果至关重要。
