Midface symmetry is an important indicator of success of complete unilateral cleft lip and palate (CUCLP) treatment. There is little literature on the long-term effects of presurgical nasoalveolar molding (PNAM) on midface symmetry in children treated for CUCLP. This study aimed to compare children with CUCLP who underwent PNAM before surgical interventions, children who did not receive PNAM, and age- and sex-matched controls in terms of midface symmetry.
We evaluated 39 frontal facial photographs of 13 patients with CUCLP who underwent PNAM as part of the treatment (group 1: PNAM), 13 patient with CUCLP who did not undergo PNAM (group 2: no nasoalveolar molding), and 13 age- and sex-matched controls. The children were evaluated in their fifth year of life. Three midline and 3 bilateral orthopometric midface landmarks were programmed using a custom software (OnyxCeph3, Image Instruments GmbH, Germany), and corresponding linear measurements from the midline were obtained and compared between the groups using 1-way analysis of variance and Scheffe's post hoc test.
Significant differences were observed between the control and CUCLP groups for the measurements of the proanasale, subnasale, and zygion. However, there were no significant differences between the PNAM and no nasoalveolar molding groups for the 6 midface landmarks.
PNAM does not seem to significantly impact the long-term midface symmetry in children with CUCLP.
面中部对称性是完全性单侧唇腭裂（CUCLP）治疗成功的重要指标。关于术前鼻牙槽骨塑形（PNAM）对接受CUCLP治疗儿童面中部对称性的长期影响的文献较少。本研究旨在比较在手术干预前接受PNAM的CUCLP患儿、未接受PNAM的患儿以及年龄和性别匹配的对照组在面中部对称性方面的差异。
我们评估了13例接受PNAM作为治疗一部分的CUCLP患者（第1组：PNAM）、13例未接受PNAM的CUCLP患者（第2组：未进行鼻牙槽骨塑形）以及13例年龄和性别匹配的对照组的39张正面面部照片。这些儿童在5岁时接受评估。使用定制软件（OnyxCeph3，德国Image Instruments GmbH公司）对三个中线和三个双侧面部测量的面中部标志点进行编程，并获得从中线的相应线性测量值，使用单因素方差分析和谢费事后检验在各组之间进行比较。
在鼻前点、鼻下点和颧突点的测量中，对照组和CUCLP组之间观察到显著差异。然而，在6个面中部标志点上，PNAM组和未进行鼻牙槽骨塑形组之间没有显著差异。
PNAM似乎对CUCLP患儿的长期面中部对称性没有显著影响。
