In younger individuals, the distance from the lower edge of the eyebrow to the pupil is 2–2.5 cm, while the distance from the upper edge of the eyebrow to the hairline is 5 cm, with the tail of the eyebrow positioned along the upper edge of the brow bone. With aging, the forehead skin loses its elasticity. Combined with the effects of gravity, the loosened skin inevitably shifts downward, causing eyebrow ptosis.The distance between the lower edge of the eyebrow and the midpoint of the pupil shortens, and the outer end of the eyebrow descends below the brow bone. Three surgical methods address eyebrow ptosis:
Brow Lift with Upper Brow Skin Resection: Directly excising skin along the upper edge of the outer brow elevates this area, correcting ptosis. However, this leaves a scar along the upper margin of the outer brow.
Traditional Forehead Lift with Brow Lift: An incision is made within the hairline or along the hairline, extending from the front of the right ear over the top of the head to the front of the left ear, typically 20–30 cm in length. The entire forehead skin is then separated from the underlying frontal bone for lifting.While this procedure yields highly noticeable results, it involves a longer incision, greater tissue trauma, increased patient discomfort, slower recovery of scalp sensation, and leaves a longer, more visible scar.
Endoscopic Brow Lift: Features a smaller incision with scarring concealed within the hairline. However, when accompanied by forehead wrinkles, frown lines, or crow's feet, a full forehead lift or endoscopic forehead lift is essential to comprehensively address drooping brows and skin aging wrinkles.
