摘要目的:测量广东汕头年轻单睑女性双上睑软组织部分参数，探讨睑裂不对称的规律。方法:2018年3月至2019年7月，汕头大学医学院第一附属医院医学美容中心测量年轻单睑女性108例，年龄18~35岁，平均24.6岁。术前对双侧睑裂长度、睑裂宽度、睑裂倾斜度、中央眉睑间距进行测量，术中对切除眶隔脂肪进行称重，直接测量和照片测量术前术后数据。统计各睑裂测量项目不对称性的发生率。结果:108例患者睑裂长度：左眼(25.76±1.50) mm，右眼(26.04±1.55) mm，进行配对 t检验后， t＝2.93；睑裂高度：左眼(9.70±1.15) mm，右眼(9.49±1.05) mm， t＝3.12；睑裂倾斜度：左眼(9.77±2.57)°，右眼(9.67±2.28)°， t＝2.01；中央眉睑间距：左眼(12.05±1.61) mm，右眼(12.32±1.69) mm， t＝2.66。术中切除的眶隔脂肪重量：左眼(0.20±0.11) g，右眼(0.22±0.12) g， t＝2.29；术前术后数据比较，差异均有统计学意义(均 P<0.05)。 结论:广东汕头行重睑成形术者双上睑存在着明显不对称，左眼睑裂高度大于右眼患者较多见，右眼睑裂长度、眉睑间距、眶隔脂肪含量大于左眼者多见，临床评估与手术时需注意。

abstractsObjective:To measure the partial parameters of the soft tissues of upper eyelid in young women with single eyelid in Shantou City, Guangdong Province, and to explore the asymmetry rate of the left and right palpebral fissure and its regularity.Methods:From March 2018 to July 2019, the Medical Cosmetology Center of the First Affiliated Hospital of Shantou University Medical College measured 108 young women with single eyelid, aged 18-35 years, with an average age of 24.6 years. Before operation, palpebral fissure width (PFW), palpebral fissure height (PFH), palpebral fissure inclination (PFI) and central eyebrow height (CEH) were measured. The resected intra-orbital septum fat pad during the procedure was weighed. Both direct measurement and the photo measurement were used to obtain the average value of the two sets of data for final analysis. We calculated out the incidence rate of asymmetry of each palpebral item.Results:The paired t-test showed that the mean value of PFW was (25.76±1.50) mm on the left and (26.04±1.55) mm on the right ( t=2.93); the mean value of PFH was (9.70±1.15) mm on the left and (9.49±1.05) mm on the right ( t=3.12); the mean value of PFI was (9.77±2.57)° on the left and (9.67±2.28)° on the right ( t=2.01); the mean value of CEH was (12.05±1.61) mm on the left and (12.32±1.69) mm on the right ( t=-2.66); the mean value of the weight of the intra-orbital septum fat pad was (0.20±0.11) g on the left and (0.22±0.12) g on the right ( t=2.29). There were significant differences between the two sets of data (all P<0.05). Conclusions:The asymmetric phenomenon of the upper eyelid is commonly found in Shantou young female undergraduates, in which the PFH in the left is higher than that in the left; the PFW, the CEH, the weight of the intra-orbital septum fat pad in the right more commonly found than that in the left.. This study provides a certain reference for the clinical evaluation of the operation.
