A Novel Preoperative Design to Address Dermatochalasis in Asian Upper Blepharoplasty.

[BACKGROUND] The preoperative design for the amount of skin excision of the upper eyelid is a common procedure in Asian blepharoplasty, but there lack of an effective method addressing dermatochalasis to acquire esthetically pleasing results. Our aim was to propose an alternative technique to determine the skin excision combined with the esthetics of eyes for correcting skin laxity and therefore to create attractive double eyelids.

[MATERIALS AND METHODS] The preoperative invaginating-simulating design combined with esthetic criteria for determining the amount of excised skin were performed during blepharoplasty. The Strasser grading system and the Global Aesthetic Improvement Scale were evaluated by analyzing the preoperative and 6-month-postoperative photographs.

[RESULTS] One hundred forty-two patients were included. The general outline of the "optimal incision" took on a knife in shape with a mean of 2.2±3.32 points of Strasser grading score. A total of 130 of 142 patients (91.5%) were judged as "good results" and 12 of 142 patients (8.5%) were judged as "mediocre". The Global Aesthetic Improvement Scale showed a significant cosmetic improvement with the result of 89.4%(127 of 142 patients) for "very much improved", 7.8% for "much improved" and other patients for "improved". No severe complications were observed.

[CONCLUSIONS] This preoperative design approach has been proven to be effective to address dermatochalasis (especially for lateral hooding) by simulating the expected appearance of a double eyelid combined with esthetic criteria of eyes simultaneously, which can contribute to achieving upper-lid rejuvenation and beautiful and natural outcomes.
