Abstract

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.
