Abstract: Objective    To measure the anatomical parameters of superficial temporal artery trunk by three-dimensional measurement, and to provide anatomical reference for related clinical operation. Methods     Original images of 70 patients aged 30-79 years old (mean 60.0 years old) who underwent cranial CTA examination in Affiliated Hospital of Zunyi Medical University from January 2021 to June 2021 were selected, including 32 females and 38 males. After the superficial temporal artery was reconstructed by professional medical 3D reconstruction software (MIMICS), the anatomical parameters of the main trunk of the superficial temporal artery were measured: length of the superficial temporal artery (AB), length of the C-type bending (CD), distance between the external auditory canal and the superficial temporal artery (EF) measured horizontally, and curvature of the C-type bending.   Results   There was no statistical difference between male and female in 3D visualization model. There was no statistical difference among different age groups. C-type curve was found in 66% of the zygomatic arch of the superficial temporal artery. The bending length of type C was linearly correlated with the bending degree y= (0.82788±0.03574) x+ (-0.02919± 0.00388). Eighty-nine percent of the C-type bending had branching vessels. The branches from the C-type bending were 7% of the middle temporal artery, 64% of the zygomatic orbital artery, and 29% of the middle temporal and zygomatic orbital artery. In the data of 70 cases, one parietal branch of the superficial temporal artery was absent, and the bifurcation point of the frontoparietal branch of the superficial temporal artery was located at the zygomatic arch. The bifurcation point was in the midpoint of C-type bending.   Conclusions Three-dimensional visualization can accurately measure the anatomical parameters of the superficial temporal artery, and provide anatomical reference for relevant clinical operations.
