Design of the excision lines

Design of the upper and lower skin excision lines. (A) While an assistant lifts the brow so that the upper eyelid skin is expanded to 80% to 90% of its full length (black arrow), the desired double fold line is drawn, which is the lower skin excision line. (B) The line is drawn at the same level after the lifted brow is released, which is the upper skin excision line. The length from the upper eyelid margin to the lower incision line while the brow is lifted, and to the upper incision line while the brow is released, is the same (a=a') (red arrow).
