Abstract:
Objective:To investigate the safety and outcome of a new method to repair the morphological defects after epicanthic fold surgery.Methods:Retrospective analysis was commenced for patients from September 2020 to January 2022 at Chengdu Qingyang Yayuan Medical Beauty Clinic who received new methods to repair postoperative dysplasia of epicanthus. This method was improved on the basis of V-Y advancing skin flap. A flipped skin flap was made from the normal skin of the lower eyelid as the "posterior flap", which was diagonally crossed and covers the front of the inner canthus angle. Then, a skin muscle sliding flap was made from the upper eyelid as the "anterior flap", covering the surface of the posterior flap to form a new "epicanthus". Follow up were focused on the incidence of postoperative complications, patient satisfaction, and improvement in indicators such as eye spacing, inner canthus scars, lacrimal caruncle exposure, and inner canthus symmetry. Patient satisfaction was divided into three levels: satisfaction, average effect, and dissatisfaction. The evaluation of epicanthus scars was referred to the observer scar assessment scale (OSAS), which evaluates scar width, color, protrusion, and surface roughness in four aspects. The scores of the last three are all 1-10 points. Higher the score, the more severe the scar was. If the exposure of the lacrimal caruncle was less than 70%, it was considered undercorrected, 70%-80% is considered appropriate, and >80% is considered overcorrected. The symmetry of the inner canthus can be divided into three levels: symmetrical, basic symmetrical, and asymmetrical. Normally distributed econometric data were expressed as Mean±SD and analyzed by paired t-test. Results:A total of 34 patients (68 eyes) were included, including 4 males and 30 females, aged 20-38 years, with an average age of 27.4 years. Among them, there were 8 cases of inner canthal scars, 4 cases of excessive exposure of lacrimal caruncle, and 22 cases of inner canthal scars combined with excessive exposure of lacrimal caruncle. Postoperative follow-up was 6-12 months, with an average of 9.3 months. 28 cases (82.4%) were satisfied with the surgical results, 4 cases (11.7%) reported average results, and 2 cases (5.9%) were dissatisfied. After surgery, the distance between the eyes significantly increased compared to before surgery [(36.9±1.5) mm vs. (33.2±1.1) mm, P<0.05], the width of the inner canthus scar [(2.3±0.3) mm vs. (4.6±0.4) mm, P<0.05], and the surface roughness [(1.8±0.3) points vs. (3.3±0.5) points, P<0.05] were all significantly improved. Postoperative exposure of lacrimal caruncle: 5 eyes (7.4%) were undercorrected, 60 eyes (88.2%) were appropriate, and 3 eyes (4.4%) were overcorrected. Postoperative symmetry of inner canthus: 33 cases (97.1%) had symmetrical or almost symmetrical inner canthus, and 1 case (2.9%) had asymmetric inner canthus. All patients did not experience infection, delayed healing, or flap necrosis. Conclusion:This method of repair the defects after epicanthic fold correction is safe and effective, with high postoperative satisfaction, and can be widely used in clinical practice.
