Fig. 1From: Barrel-shaped design of the forearm free flap for lower lip reconstruction: a pilot case-control studyIllustrates the barrel-shaped design of the radial forearm free flap. (a) If the horizontal defect was “X” cm and (b) the vertical defect from the outer skin to the inner mucosa surface was “Y” cm. (c) The flap was harvested with a longitudinal dimension of X − 1 cm and with a transverse dimension of Y + 2 cm in a barrel-like shapeBack to article page
