OBJECTIVES: 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.
