Abstract：
OBJECTIVE: The aim of this study was to establish the relationship of facial artery with nasolabial fold by color Doppler sonography and to determine facial artery variations and their relationship with age, gender, or hemifaces.
METHODS: The study included 188 patients (94 women, 94 men) aged 18-60 years. Overall, 376 facial arteries in both hemifaces were evaluated for the course within nasolabial fold, symmetry, and relationship with gender.
RESULTS: The mean age of the patients was 39.29 ± 12.81 years. Type A (55.7%) was the most common type in both hemifaces. There was no significant relationship between the course of facial artery and age (P > .05). Asymmetrical course of facial artery was more common in females (54.3%). In both genders, type A was the type with highest symmetry detected.
CONCLUSIONS: Nasolabial fold is one of the important facial regions for filler injection. To prevent vascular injection, course of facial artery should be identified within the nasolabial fold. Type A was the most common type in both hemifaces and genders. Although the rates were close to each other, asymmetry in the course of the facial artery was observed in most of the patients. Ultrasonographic examination which is non-invasive and non-ionizing imaging method can be performed carefully before filler injection to determine vascular tissues.

摘要：
目的：本研究的目的是通过彩色多普勒超声检查建立面动脉与鼻唇沟的关系，并确定面动脉变异及其与年龄的关系。性别,或半边脸。
方法：该研究包括188名患者（94名女性，94名男性）18-60岁。总的来说,评估了两个半面的376条面部动脉在鼻唇沟内的过程，对称性，与性别的关系。
结果：患者的平均年龄为39.29±12.81岁。A型（55.7％）是两种半脸中最常见的类型。面动脉的病程与年龄无明显关系(P>.05)。面动脉不对称在女性中更为常见(54.3%)。在两种性别中，A型是检测到的对称性最高的类型。
结论：鼻唇沟是填充剂注射的重要面部区域之一。为了防止血管注射，应在鼻唇沟内确定面动脉的走向。A型是半脸和性别中最常见的类型。尽管利率彼此接近，在大多数患者中观察到面部动脉的过程不对称。超声检查是非侵入性和非电离成像方法，可以在填充剂注射之前仔细进行以确定血管组织。
