Fig. 14.

(A) Range of dissection. Fibrocutaneous dissection of the lower eyelid is done minimally until the skin fold completely disappears. It is not necessary to dissect to the end of the fold. Subcutaneous dissection of the upper eyelid and reposition of muscle are done gradually until the designed crease is formed without tension (B). When the fibrocutaneous flap is elevated in the lower eyelid and the cutaneous flap in upper eyelid, point D of the nasal flap tends to move laterally. Notice the transverse shrinkage of the fibrocutaneous flap on the lower eyelid. (C) When the fibrocutaneous flap is elevated in both the upper and lower eyelids, point D of the nasal flap tends to move superolaterally .
