本研究的目的是评估唇裂和/或腭裂（CLP）修复对儿童在最大自愿追逐式闭唇运动中产生的多向闭唇力（LCF）的影响。将30例日本患儿分为对照组和修复型单侧CLP组（RUCL），后者又分为单侧唇裂及/或牙槽（UCLA）组和单侧唇裂及腭裂（UCLP）组。最大自愿LCF记录在八个方向。在RUCL组和对照组之间，任何定向LCF （DLCF）或总LCF均无显著差异。对照组上唇两侧斜向DLCF呈对称分布，而RUCL组非裂侧斜向DLCF明显大于裂侧斜向DLCF。对照组和UCLA组上下方向均有对称的垂直DLCF， UCLP组下方向获得的垂直DLCF明显大于上方向。这些结果表明，修复的CLP患儿表现出定向特异性受损，这可能导致继发性畸形。这些发现有助于我们理解唇腭裂术后CLP患者继发畸形的病理。我们建议，基于在最大程度的自愿闭唇运动中产生的多向LCF的方向特异性对闭唇功能的定量评估有助于评估闭唇功能障碍的性质。
The objectives of this study were to estimate the effects of cleft lip and/or palate (CLP) repair on the multidirectional lip-closing forces (LCF) produced during maximum voluntary pursing-like lip-closing movement in children. Thirty Japanese children were divided into the control group and repaired unilateral CLP (RUCL) group, which was subdivided into the unilateral cleft lip and/or alveolus (UCLA) and the unilateral cleft lip and cleft palate (UCLP) groups. The maximum voluntary LCF were recorded in eight directions. No significant differences in any of the directional LCF (DLCF) or total LCF were observed between RUCL and control groups. Symmetrical DLCF were seen in the oblique directions on both sides of the upper lip in the control group, while the oblique DLCF on the non-cleft side was significantly greater than that on the cleft side in RUCL group. Furthermore, symmetrical vertical DLCF were observed in the upper and lower directions in control and UCLA groups, while the vertical DLCF obtained from the lower direction was significantly greater than that obtained from the upper direction in UCLP group. These results indicate that children with repaired CLP display impaired directional specificity, which may cause secondary deformities. These findings aid our understanding of the pathology of secondary deformities in CLP patients after primary surgery for cleft lip or palate. We propose that quantitative assessments of lip-closing function based on the directional specificity of the multidirectional LCF produced during maximum voluntary pursing-like lip-closing movement are useful for assessing the nature of lip-closing dysfunctions.
