我们评估了使用矫形矫治器进行术前鼻牙槽成型 (NAM) 的效果，并将其与被动矫形方法（Hotz 板，HP）进行比较，重点关注鼻孔形态以及牙槽和腭裂间隙的宽度。研究对象为2004年至2011年在筑波大学医院接受初次唇腭裂手术的28例单侧完全性唇腭裂患者。其中13例患者术前接受NAM治疗（NAM组），15例患者术前接受HP治疗（HP组）。根据左右鼻孔对称性评估手术结果，通过面积比、周长比、长宽比（患侧长宽比/健侧长宽比）和 Hausdorff 距离来测量。此外，在骨板固定和初次唇整形术时测量牙槽裂和腭裂宽度。术前NAM组的纵横比明显小于HP组。两组患者术后的长宽比、周长比和豪斯多夫距离均明显小于术前。 NAM组的牙槽裂和腭裂间隙宽度显着变窄，并且NAM开始时的裂隙间隙与唇形整形术后的Hausdorff距离显着相关。我们发现，NAM 比 HP 更有效地改善了初次唇整形术后鼻孔的形状并减少了腭裂间隙，并且腭裂间隙的宽度与鼻孔的手术结果相关。
We evaluated the effects of presurgical nasoalveolar molding (NAM) with an orthopedic appliance and compared them with a passive orthopedic method (Hotz plate, HP), focusing on the naris morphology and width of the alveolar and palate cleft gap. The subjects were 28 unilateral complete cleft lip and palate patients treated with primary cheiloplasty at Tsukuba University Hospital from 2004 to 2011. Thirteen patients were treated preoperatively with NAM (NAM group), and 15 with HP (HP group). The surgical outcome was assessed according to left-right naris symmetry, as measured by the area ratio, perimeter ratio, aspect a/u ratio (aspect ratio of the affected side/aspect ratio of the unaffected side), and Hausdorff distance. In addition, the alveolar and palate cleft width was measured at the times of orthopedic plate setting and primary cheiloplasty. The aspect ratio was significantly smaller in the NAM group than in the HP group before the operation. In both groups, the aspect ratio, perimeter ratio, and Hausdorff distance were significantly smaller after the operation than before. The width of the alveolar and palate cleft gap was significantly narrowed in the NAM group, and the cleft gap at the initiation of NAM correlated significantly with the Hausdorff distance after cheiloplasty. We found that NAM improved the form of the naris after primary cheiloplasty and decreased the palate cleft gap more effectively than HP and that the width of the palate cleft gap was correlated with the surgical outcome of the naris.
