Abstract

Introduction: The levator veli palatini (LVP) muscle has two segments with distinct roles in velopharyngeal function. Previous research suggests longer extravelar segments with shorter intravelar segments may lead to a more advantageous mechanism for velopharyngeal closure. The purpose of this study was to examine whether the distribution of the LVP intravelar and extravelar segments differs between children with cleft palate with and without VPI and controls.

Methods: The study included 97 children: 37 with cleft palate +/- lip with VPI, 37 controls, and 19 with cleft palate with normal resonance. Measures included mean LVP length, mean extravelar LVP length, and intravelar LVP length.

Results: Overall mean LVP length was similar (P = .267) between controls and children with cleft palate (with and without VPI). However, there was a significant difference (P < .001) between group for both intravelar and extravelar LVP lengths: the intravelar segment was significantly longer in those with VPI compared to controls and children with cleft palate and normal resonance; and the extravelar segment was significantly shorter in those with VPI compared to controls and children with cleft palate and normal resonance.

Conclusions: Results from this study demonstrate a significant difference between the distribution of the functional segments of the LVP among children with VPI, with a more disadvantageous distribution of the muscle segments among those with VPI.

髂胫束：所有部分都一样吗？

简介腭上提肌（LVP）有两个节段，在咽后功能中起着不同的作用。以前的研究表明，较长的瓣外肌节和较短的瓣内肌节可能会导致更有利的咽喉闭合机制。本研究的目的是探讨伴有或不伴有VPI的腭裂儿童与对照组儿童的LVP瓣内和瓣外节段的分布是否存在差异：研究包括 97 名儿童：方法：研究包括 97 名儿童：37 名腭裂+/-唇裂伴 VPI 儿童、37 名对照组儿童和 19 名腭裂伴正常共振儿童。测量指标包括平均LVP长度、平均侧外LVP长度和侧内LVP长度：结果：对照组和腭裂儿童（有 VPI 和无 VPI）的平均 LVP 长度总体相似（P = .267）。然而，对照组和腭裂患儿（有 VPI 和无 VPI）的平均 LVP 长度存在显著差异（P本研究结果表明，VPI 患儿的 LVP 功能节段分布存在显著差异，VPI 患儿的肌肉节段分布更为不利。
