Cleft lip in the presence or absence of a cleft palate is a major public health problem. However, few studies have been published concerning the soft-tissue morphology of cleft lip infants. Currently, obtaining reliable three-dimensional (3D) surface models of infants remains a challenge. The aim of this study was to investigate a new way of capturing 3D images of cleft lip infants using a structured light scanning system. In addition, the accuracy and precision of the acquired facial 3D data were validated and compared with direct measurements.
Ten unilateral cleft lip patients were enrolled in the study. Briefly, 3D facial images of the patients were acquired using a 3D scanner device before and after the surgery. Fourteen items were measured by direct anthropometry and 3D image software. The accuracy and precision of the 3D system were assessed by comparative analysis.
The anthropometric data obtained using the 3D method were in agreement with the direct anthropometry measurements. All data calculated by the software were 'highly reliable' or 'reliable', as defined in the literature. The localisation of four landmarks was not consistent in repeated experiments of inter-observer reliability in preoperative images (P<0.05), while the intra-observer reliability in both pre- and postoperative images was good (P>0.05).
The structured light scanning system is proven to be a non-invasive, accurate and precise method in cleft lip anthropometry.
唇裂伴或不伴腭裂是一个主要的公共健康问题。然而，关于唇裂婴儿的软组织形态学的研究很少。目前，获取婴儿可靠的三维（3D）表面模型仍然是一个挑战。本研究旨在探讨一种使用结构光扫描系统获取唇裂婴儿 3D 图像的新方法。此外，还验证和比较了获得的面部 3D 数据的准确性和精度与直接测量值。
本研究纳入了 10 例单侧唇裂患者。简要地说，使用 3D 扫描仪设备在手术前后获取患者的 3D 面部图像。通过直接人体测量和 3D 图像软件测量了 14 项指标。通过比较分析评估了 3D 系统的准确性和精度。
使用 3D 方法获得的人体测量数据与直接人体测量测量值一致。文献中定义的所有软件计算的数据均为“高度可靠”或“可靠”。在术前图像的观察者间可靠性的重复实验中，四个标志点的定位不一致（P<0.05），而在术前和术后图像的观察者内可靠性均良好（P>0.05）。
结构光扫描系统被证明是一种用于唇裂人体测量的非侵入性、准确和精确的方法。
