To evaluate 3-dimensional (3-D) photogrammetry as a tool for assessing the postoperative head shape of patients who had undergone cranial vault remodeling for metopic synostosis.
We prospectively analyzed images of patients with metopic craniosynostosis who had undergone anterior cranial vault remodeling and age-matched controls. To ensure standardized facial orientation, each 3-D image was positioned to "best fit" the preoperative face by aligning 6 soft tissue landmarks. Forehead measurements were taken from a standardized position behind the surface of the face to landmarks placed in a ray configuration across the forehead.

PATIENTS, PARTICIPANTS: Thirteen pediatric patients with metopic craniosynostosis who had undergone anterior cranial vault remodeling and age-matched controls.
Images were taken preoperatively, immediately postoperatively, and over 1-year postoperatively.
Forehead contours preoperatively and postoperatively, with statistics performed using a multivariate analysis of variance shape analysis.
Mean postoperative follow-up was 1.8 (0.6) years. The average distance from the origin to forehead landmarks was 55.1 (3.4) mm preoperatively, 59.3 (0.7) mm immediate postoperatively, 59.1 (1.0) mm 1-year postoperatively, and 59.4 (0.6) mm in controls. Postoperative metopic forehead contours varied significantly from preoperative contours ( P < .01), while there was no statistical difference between the 2 postoperative time points ( P = .70). One-year postoperative patients were not significantly different from their age-matched controls ( P > .99).
Preoperative metopic forehead contours varied significantly from postoperative contours. Cranial reconstructions approximated the foreheads of normal controls, and reconstructions were stable at more than 1-year follow-up.
评估三维（3-D）摄影测量法作为一种工具，用于评估因冠状缝早闭而接受颅穹窿重塑手术患者的术后头部形状。
我们前瞻性地分析了接受前颅穹窿重塑手术的冠状缝早闭患者以及年龄匹配的对照组的图像。为确保面部方向标准化，通过对齐6个软组织标志点，将每张3-D图像定位为“最佳拟合”术前面部。从前额表面后方的标准化位置到沿前额呈射线配置放置的标志点进行前额测量。
学术教学医院。
患者、参与者：13例接受前颅穹窿重塑手术的小儿冠状缝早闭患者及年龄匹配的对照组。
术前、术后即刻及术后1年以上拍摄图像。
术前和术后的前额轮廓，使用多变量方差分析形状分析进行统计。
术后平均随访1.8（0.6）年。术前从原点到前额标志点的平均距离为55.1（3.4）mm，术后即刻为59.3（0.7）mm，术后1年为59.1（1.0）mm，对照组为59.4（0.6）mm。术后冠状缝前额轮廓与术前轮廓有显著差异（P <.01），而两个术后时间点之间无统计学差异（P =.70）。术后1年的患者与年龄匹配的对照组无显著差异（P >.99）。
术前冠状缝前额轮廓与术后轮廓有显著差异。颅骨重建接近正常对照组的前额，且在1年以上的随访中重建稳定。
