Objective: The superficial temporal artery is a terminal branch of the external carotid artery and its morphology is important for clinics. It supplies the parietooccipital, preauricular and temporoparietal fascial flaps. Planning the craniofacial reconstructive surgery and success is related to the morphology of the artery. It is also preferred for the revascularization of cerebral ischemia in extracranial-intracranial bypass surgery. Knowing the anatomy is important to prevent complications of dermal filler injections of lateral side of the orbit and during the biopsy for giant cell arteritis. The aim of this study is to examine the detailed anatomy of the artery. Methods: This retrospective study was carried out by evaluating the head and neck CT Angiograms at the Department of Radiology, Gazi University. Patients with significant pathologies, history of trauma and craniotomy were excluded and 129 arteries were evaluated. The zygomatic processes, marginal tubercle, tragus, uppermost of the superior and lowermost of the inferior rims of the orbit were determined. The region of the artery was divided into 4 zones according to the landmarks. Significant measurements were evaluated and the variations were classified. Statistical analyzes were performed by using the SPSS program. Results: The frontal branch was determined in all and the parietal one was found in 89.15%. The angulation of the artery and frontal-parietal branches according to the vertical axis was 17.04±9.61°, 45.08±13.13°, 23.50±11.26°, respectively. The bifurcation was located 29.21±12.92 mm superior and 12.21±6.65 mm anterior to the tragus. The nearest distance between the frontal branch and the angle of the zygomatic processes and superior orbital rim was measured as 32.83±9.89 mm, 19.72±8.17 mm, respectively. Conclusion: Anatomical variations of the superficial temporal artery and its branches are rare. Therefore, evaluation of the artery according to certain landmarks will help to reduce the risk of complications in significant procedures. [ABSTRACT FROM AUTHOR]
