To quantify the degree of perceived age change after aesthetic facial surgical procedures to provide an objective measure of surgical success.
Sixty patients undergoing various aging face surgical procedures were randomly chosen for analysis. Preoperative and postoperative photographs were evaluated. Raters were presented with photographs in a random assortment and were asked to estimate the age of the patient. Perceived age difference was defined as the difference between the chronological age and the estimated age, and the change in this value after surgery was the chief outcome of interest. Statistical models were designed to account for any effects of interrater differences, preoperative chronological age, rater group, photograph order, or surgical procedure performed.
Our patient population was divided into the following 3 groups based on the surgical procedure performed: group 1 (face- and neck-lift [22 patients]), group 2 (face- and neck-lift and upper and lower blepharoplasty [17 patients]), and group 3 (face- and neck-lift, upper and lower blepharoplasty, and forehead-lift [21 patients]). Adjusted means demonstrated that patient ages were estimated to be 1.7 years younger than their chronological age before surgery and 8.9 years younger than their chronological age after surgery. The effect was less substantial for group 1 patients and was most dramatic for group 3 patients, who had undergone all 3 aging face surgical procedures.
Our study is novel in that it quantifies the degree of perceived age change after aging face surgical procedures and demonstrates a significant and consistent reduction in perceived age after aesthetic facial surgery. This effect is more substantial when the number of surgical procedures is increased, an effect unrelated to the preoperative age of a patient and unaffected by other variables that we investigated. The ability to perceive age correctly is accurate and consistent.
量化面部美容手术后感知到的年龄变化程度，以提供手术成功的客观衡量标准。
随机选择60例接受各种面部抗衰手术的患者进行分析。对术前和术后照片进行评估。向评分者随机展示照片，并要求他们估计患者的年龄。感知年龄差异定义为实际年龄与估计年龄之间的差异，而该值在手术后的变化是主要关注的结果。设计统计模型以考虑评分者差异、术前实际年龄、评分者组、照片顺序或所实施手术的任何影响。
根据所实施的手术，我们的患者群体分为以下3组：第1组（面部和颈部提升术[22例患者]），第2组（面部和颈部提升术以及上下睑成形术[17例患者]），第3组（面部和颈部提升术、上下睑成形术以及额部提升术[21例患者]）。调整后的均值表明，患者年龄在术前被估计比实际年龄小1.7岁，术后比实际年龄小8.9岁。这种效果在第1组患者中不太明显，在接受了所有3种面部抗衰手术的第3组患者中最为显著。
我们的研究具有创新性，因为它量化了面部抗衰手术后感知到的年龄变化程度，并表明美容面部手术后感知年龄有显著且持续的降低。当手术数量增加时，这种效果更明显，该效果与患者的术前年龄无关，也不受我们所研究的其他变量影响。正确感知年龄的能力是准确且一致的。
