Distribution of the superficial temporal artery in the Chinese adult

Abstract

The superficial temporal artery is important in head and neck surgery. Ethnologic variation may affect surgical procedure. In this study, we evaluated the variations of the artery in Chinese adults. We measured its bifurcating location, the diameter of its vessels, and its relationship to nearby structures. A total of 26 cadavers with 52 superficial temporal arteries were examined in 3 consecutive years. The superficial temporal artery ran 1.14 cm anteriorly to the bony external auditory canal. The average diameters of the superficial temporal artery, frontal branch, and parietal branch were 2.14, 1.61, and 1.68 mm, respectively. In 45 of 52 cases (86.5 percent), bifurcation of the artery occurred well above the zygomatic arch. The present study thus demonstrated that the superficial temporal artery in the Chinese adult differs from that in the Caucasian and has provided a detailed anatomic distribution analysis of the superficial temporal artery in Chinese adults, which should benefit the clinician in dealing with operation procedures related to this artery.
