PURPOSE
To describe the course and configuration of the superficial temporal artery (STA) around the zygomatic arch.
METHODS
Volume rendered 3D reconstructions of computed tomography angiography of 25 healthy patients were performed and analyzed at Duke University Hospitals.
RESULTS
The STA coursed over the zygomatic arch or over the condylar process of the mandible in all cases (25/25 pts, 100 %). The STA courses over the posterior zygomatic arch in 23/25 pts (92 %), creating a characteristic "C" shape half-buttonhole configuration as it embraces the arch. When the STA travels posterior to the zygomatic arch, there is no C shape configuration (2/25 pts, 8 %). The STA bifurcates distal to the zygomatic arch in 24/25 pts (96 %).
CONCLUSIONS
The "C" shape half-buttonhole configuration is a useful identifying characteristic of the most common course of the STA-over the posterior zygomatic arch before it bifurcates.
目的
描述颞浅动脉（STA）在颧弓周围的走行及形态。
方法
对杜克大学医院25例健康患者的计算机断层血管造影进行容积再现三维重建并分析。
结果
所有病例（25/25例，100%）中，STA走行于颧弓上方或下颌骨髁突上方。23/25例（92%）中，STA走行于颧弓后部上方，环绕颧弓时形成特征性的“C”形半扣眼形态。当STA走行于颧弓后方时，不存在“C”形形态（2/25例，8%）。24/25例（96%）中，STA在颧弓远端分叉。
结论
“C”形半扣眼形态是STA在颧弓后部上方分叉前最常见走行的一个有用识别特征。
