Facial appearance is influenced by the anatomic relationship of the eyebrow and eyelid, and surgical procedures on these structures attempt to restore or preserve not only symmetry but also normal appearance. To provide useful benchmarks for such interventions, we measured the eyebrow height, upper eyelid crease height, and amount of visible pretarsal skin of 143 white subjects who had no facial abnormalities. An age effect was observed for all measures, indicating a direct relationship with age until the middle age range (41 to 60 years), when mean estimates leveled off or decreased somewhat relative to younger age groups. Within the 41- to 60-year age group, for example, the average (S.D.) values for pretarsal skin height, eyelid crease height, and eyebrow height were 1.4 mm (1.1 mm), 6.4 mm (1.2 mm), and 6.4 mm (1.8 mm), respectively. Eyebrow and pretarsal skin heights were greater in females than males, and eyelid crease height showed similar gender-related trends. With increasing age, variation around the mean estimates for eyelid and eyebrow measurement increased, which may be indicative of variability across individuals in the physiologic response to the aging process. As expected, a high degree of intereye correlation was observed (correlation coefficients of 0.87 to 0.96). These results emphasize the importance of providing a normal anatomic relationship that relates to the patient's age and gender, as well as an outcome that is symmetric, in corrective or cosmetic procedures on the eyelid and eyebrow.
面部外观受眉毛和眼睑的解剖关系影响，针对这些结构的外科手术不仅试图恢复或保持对称性，还试图恢复或保持正常外观。为了给此类干预提供有用的基准，我们测量了143名无面部异常的白人受试者的眉高、上睑皱襞高度和睑板前可见皮肤量。所有测量指标均观察到年龄效应，表明在中年范围（41至60岁）之前与年龄呈直接关系，此时相对于较年轻年龄组，平均估计值趋于平稳或有所下降。例如，在41至60岁年龄组中，睑板前皮肤高度、眼睑皱襞高度和眉高的平均（标准差）值分别为1.4毫米（1.1毫米）、6.4毫米（1.2毫米）和6.4毫米（1.8毫米）。女性的眉高和睑板前皮肤高度大于男性，眼睑皱襞高度也呈现出类似的性别相关趋势。随着年龄的增长，眼睑和眉毛测量平均估计值周围的变异性增加，这可能表明个体在衰老过程中的生理反应存在差异。正如预期的那样，两眼之间观察到高度相关性（相关系数为0.87至0.96）。这些结果强调了在眼睑和眉毛的矫正或美容手术中，提供与患者年龄和性别相关的正常解剖关系以及对称结果的重要性。
