Một số đặc điểm giải phẫu nhánh tận thái dương - trán dây thần kinh mặt chi phối cơ trán ở người Việt trưởng thành

Abstract

 Objective: To identify some anatomical features of the frontotemporal branch of the facial nerve entering the frontal muscle in adult Vietnamese. Subject and method: 12 hemi-faces (right: 7; left: 5) of Vietnamese cadavers (average age: 73.00 ± 13.39: 52 - 88 years; 4 men and 3 women). Method: cross-sectional description with analysis. Result and conclusion: The number of frontotemporal branch of the facial nerve entering the frontal muscle were 4.92 ± 0.90 branches (4 - 7 branches). Most were 5 branches (50.0%), followed by 4 branches (33.3%). The distance from the points of the frontotemporal branch of the facial nerve entering the frontal muscle to the (d) line [passing the lateral orbital rim and root of the helix of the ear] of the first frontal branch was 28.01 ± 3.75mm and third frontal branch was 33.40 ± 3.62mm; to the (d2) line [passing the lateral orbital rim and tragation on the outer ear] of the first frontal branch was 31.83 ± 3.48mm and the third frontal branch was 37.75 ± 3.26mm
