Abstract

Objective: To evaluate anatomical characteristics of the superficial temporal artery frontal branch in adult Vietnamese. Subjects and method: Cross-sectional description by dissection of 31 first half specimens of 16 corpses. Results and conclusions: 83.8% of cases of CSF branched all the way above the cheekbones - the next arc. The origin of the artery on the xOy coordinate system, 33.11 ± 10.86 mm from the Ox axis and about 16.04 ± 8.97 mm from the Oy axis. There are 35.5% of cases this point is inside a vertical rectangle, size 20 x 30 mm. The median angle between the frontal branch and the cerebral artery is 118.81 ± 53.47 degrees. The average angle between the frontal branch and the zygomatic arch is 40.5^o. The mean length of the frontal branch body is 69.78 ± 27.93 mm. At the origin, the frontal branch has a SI of 2.19 ± 0.5 mm. Posterior frontal branch 1 appeared in 96.77%, posterior frontal branch 2 accounted for 61.29%. The middle frontal branch appeared in 80.65%. The anterior frontal branch accounted for 83.87% of the specimen. The average length of posterior frontal branch 1, posterior frontal branch 2, middle branch and anterior branch is 49.39 ± 21.78 respectively; 48.42 ± 25.92; 40.03 ± 21.49; 28.17 ± 11.30 mm. Angle with frontal artery of posterior frontal branch 1, posterior frontal branch 2, middle branch and anterior branch is: 80.47 ± 23.05 respectively; 79.47 ± 16.49; 112.88 ± 43.95; 109.52 ± 30.06 degrees. The frontal branch is terminated mainly by type I accounting for 38.7% and type II 48.4%.
