Surface landmark of the facial vein for the dermal fillers injection

ObjectiveThe purpose of this study was to describe the course of the facial vein and identification of surface landmark of the facial vein for dermal fillers injections.MethodsThirty flaps of hemiface were turned over to measure the distance between the facial vein and ala of the nose and oral commissure. The vertical distance was measured from the inferior orbital rim to the facial vein. The diameter of the facial vein and the depth from skin surface to the facial vein were measured. Anatomical relationships of the facial vein to its surrounding structure were observed.ResultsThe course of the facial vein is a large curved course without tortious from the medial canthal tendon downward along the medial orbital rim. The mean vertical distance from the facial vein to the inferior orbital rim was 6.87 ± 1.14 mm. The average horizontal distance from the facial vein to ala of nose was 21.57 ± 3.95 mm. The average horizontal distance from the facial vein to oral commissure was 27.55 ± 3.97 mm. The average depth values from skin surface to the facial vein at the level of ala of nose and oral commissure were 14.44 ± 2.90 and 15.38 ± 2.40 mm, respectively.ConclusionsThe course of the facial vein at the level of ala of nose and the oral commissure were approximately 2 and 3 cm, respectively at the depth of 1.5 cm.
