The superficial temporal artery (STA) is an important continuation of the external carotid artery. It is divided into the frontal branch and the parietal branch at or above the zygomatic arch. In the present study, a comparative analysis of the STA in patients with and without moyamoya disease (MMD) was performed using CT angiography. Patients admitted to our institution for spontaneous intracranial hemorrhage were potential candidates. In general, 25 cases (50 sides) in the MMD group and 25 cases (50 sides) in the non‑MMD group were selected for evaluation. The morphology of the STA when crossing the zygomatic arch, the association between the STA bifurcation and the zygomatic arch, the branching characteristics of the STA, the parameters of the STA bifurcation point, the diameter of the STA and the distance from the origin of the STA to the bifurcation point were selected for analysis. There were no significant differences between the two groups with regard to the association between the STA bifurcation and the zygomatic arch, the diameter of the STA or the distance from the origin of the STA to the bifurcation point. However, the bifurcation point of the STA was closer to the posterior edge of the mandibular condyle in the patients with MMD.
