Presurgical infant orthopedic appliances, such as presurgical nasoalveolar molding (PNAM) devices, are used to attain optimal conditions for primary repair of the lip and nose (PRoLN) in patients with cleft lip. We aimed to analyze the three-dimensional (3D) outcomes of PNAM using an LED surface scanner.
Fifteen patients with unilateral cleft lip and palate (CLP) were included in this study and treated using a PNAM device. The patients' faces were digitized pre- and post-PNAM using an Artec Space Spider scanner, and the scanned data were analyzed using 3D software (Geomagic Control X and ANSYS SpaceClaim). The columellar angle (CA), nostril curvature (NC) on the affected (NC_A) and unaffected (NC_U) sides, gap of cleft lip (GCL), alar width (AW), and nasal tip angle (NTA) were measured.
CA increased significantly by 10.00° and NC_A by 0.030 mm (p < 0.001). GCL decreased by 4.98 mm on average and NC_U by 0.015 mm (p = 0.029 and 0.046, respectively). AW also decreased by approximately 1.22 mm pre- and post-treatment (p = 0.002), and NTA, which shows a lateral profile, decreased by approximately 3.32° (p = 0.002).
This study confirmed the orthopedic benefits of PNAMd treatment through 3D analysis using an LED surface scanner. Further studies involving a larger number of participants are warranted to study the effects of PNAM and analyze longitudinal changes in patients with CLP.
This study shows that PNAM effectively corrects columellar deviation and nostril shape in patients with unilateral cleft lip, with 3D scanners enhancing primary lip and nose repair outcomes.
术前婴儿矫形器具，如术前鼻牙槽成形术（PNAM）装置，用于为唇裂患者的唇鼻初次修复（PRoLN）获得最佳条件。我们旨在使用 LED 表面扫描仪分析 PNAM 的三维（3D）结果。
本研究纳入了 15 例单侧唇裂腭裂（CLP）患者，采用 PNAM 装置治疗。患者的面部在使用 Artec Space Spider 扫描仪进行术前和 PNAM 后进行数字化，并使用 3D 软件（Geomagic Control X 和 ANSYS SpaceClaim）分析扫描数据。测量了鼻中隔角（CA）、患侧（NC_A）和健侧（NC_U）的鼻孔曲率（NC）、裂隙唇间隙（GCL）、鼻翼宽度（AW）和鼻尖角度（NTA）。
CA 显著增加了 10.00°，NC_A 增加了 0.030 毫米（p < 0.001）。GCL 平均减少了 4.98 毫米，NC_U 减少了 0.015 毫米（p = 0.029 和 0.046）。AW 治疗前后也分别减少了约 1.22 毫米（p = 0.002），显示侧面轮廓的 NTA 减少了约 3.32°（p = 0.002）。
本研究通过 LED 表面扫描仪的 3D 分析证实了 PNAMd 治疗的矫形益处。需要进一步的研究纳入更多的参与者，以研究 PNAM 的效果并分析唇裂患者的纵向变化。
本研究表明，PNAM 可有效矫正单侧唇裂患者的鼻中隔偏曲和鼻孔形状，3D 扫描仪可提高唇鼻初次修复的效果。
