We aimed to determine the prevalence of pre-existing asymmetry in our patients and investigate the impact of age and sex on upper facial asymmetry.
We collected images from 155 patients who were undergoing upper eyelid blepharoplasty and MRD1 (marginal reflex distance 1), TPS (tarsal plate show), and BFS (brow fat span) measurements were extracted by ImageJ software. The relationship between asymmetry and age and gender was assessed by comparing the mean differences of these metrics. A generalized linear model (GLM) was used to compare the outcomes of the study. P-value < 0.05 was considered significantly different in all tests.
Pre-operative asymmetry was present in 112 (72%) patients. Among the cases, 61 (39%), 40 (26%), and 24 (15.5%) patients had more than 1mm of asymmetry in BFS, TPS, and MRD1, respectively. Males under 50 years old had the most asymmetry in the preorbital area. Comparing men under 50 years old with the other groups showed that the mean ± SD of absolute differences of TPS was significantly higher in this group (all P< 0.00), but pairwise comparison for MRD1 and BFS indicated no significant correlation between age, gender, and the mean asymmetry of these parameters (overall test P = 0.70 for MDR1 and P = 0.45 for BFS).
Most patients have asymmetry before surgery without being aware of it. Awareness of this asymmetry and the relationship between facial asymmetry and age and gender is essential to prevent dissatisfaction due to the probable post-operative asymmetry and unrealistic expectations.
我们旨在确定患者中预先存在的不对称情况的患病率，并研究年龄和性别对上睑面部不对称的影响。
我们收集了155例行上睑成形术患者的图像，并通过ImageJ软件提取了MRD1（边缘反射距离1）、TPS（睑板显示）和BFS（眉脂肪跨度）测量值。通过比较这些指标的平均差异来评估不对称与年龄和性别的关系。使用广义线性模型（GLM）比较研究结果。在所有测试中，P值<0.05被认为具有显著差异。
112例（72%）患者术前存在不对称。其中，分别有61例（39%）、40例（26%）和24例（15.5%）患者的BFS、TPS和MRD1不对称超过1mm。50岁以下男性眶前区不对称最为明显。将50岁以下男性与其他组进行比较发现，该组TPS绝对差异的均值±标准差显著更高（所有P<0.00），但MRD1和BFS的两两比较表明年龄、性别与这些参数的平均不对称之间无显著相关性（MDR1总体检验P = 0.70，BFS总体检验P = 0.45）。
大多数患者术前存在不对称但未意识到。了解这种不对称以及面部不对称与年龄和性别的关系对于防止因可能出现的术后不对称和不切实际的期望导致的不满至关重要。
