目的:研究术前术后眼外形及相关眉眼比例关系变化,探讨一种简单有效的内眦赘皮矫正方法.方法:受术者60例共120只眼,采用倒L法内眦成形联合切开法重睑术,术后2个月开始随访,测量并比较术前及随访时双侧睑裂宽度、容貌睑裂长度、内眦间距、睫毛暴露长度及上翘度的变化,同时对眉眼间距、容貌睑裂长度及内眦间距间相关比例关系进行描述.结果:术后内眦角暴露良好,3个月后切口瘢痕不明显.双侧睑裂增大、睫毛暴露长度及上翘度增加,经配对样本t检验结果表明术前术后差异有统计学意义(P<0.01),术后经内眦点的垂线和水平线、眉峰点的水平线及容貌外眦点的垂线,可构成一正方形结构.结论:经倒L法内眦赘皮矫正联合切开法重睑术后内眦及重睑形态良好,新的眉眼比例关系更自然、和谐,增加眼部美感,手术效果满意,值得临床推广.%Objective To study the morphological changes of external eyes before and after epicanthoplasty combined with blepharoplasty and to explore a simple and efficient method to correct epicanthus. Methods A total of 120 eyes in 60 patients were operated on with the inverted L-sharp epicanthoplasty combined with double-eyelid blepharoplasty and the follow-up began 2 months after the surgery. The height and physiognomic length of the eyelid and the length and angle of the eyelash were measured and compared with preoperative meansurements, as well as the distance of the inner canthus. The ratios between the inner-canthus distance and the physiognomic eyelid breadth and the diameter of eyebrow and eye were also described. Results The contours of the eyelid fissure and the double-eyelid were natural and the surgical scare was seen unconspicuous 3 months after the operation. Changes in the palpebral fissure , the angel and length of the exposed eyelash were all significantly different by paired-sample t test (P < 0.01). The vertical and horizontal lines through the entocanthion and the vertical line through the gnomic ectocanthion combined with the horizontal line through the brow ridge formed a square structure. Conclusions This inverted L-shape epicanthoplasty combined with blepharoplasty may be effective in reconstructing the contours of the entocanthions as well as the shape of the double eyelids. It can also achieve better cosmetic effects in the proportional relation between the eyes and eyebrows. Therefore, it deserves clinical promotion.
