To avoid a static double-eyelid fold characterized by nonmobile overdepression of the fold, I propose a new surgical approach of using septoaponeurosis junctional thickening (SAJT) to create a dynamic fold. I introduce a double-eyelid surgery technique using the SAJT. This SAJT fixation technique creates a dynamic double-eyelid fold. My study showed a high patient satisfaction rate and that the resulting fold mimics the movement of the congenital supratarsal fold in Asians.
