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.
方法:该研究包括97名儿童:37名腭裂+/-唇伴VPI,37个控件,19腭裂正常共振。措施包括平均LVP长度,平均外行程LVP长度,和内LVP长度。
结果:对照组和腭裂患儿(有无VPI)的总平均LVP长度相似(P=0.267)。然而,组内和外动脉LVP长度组之间存在显著差异(P<.001):与对照组和腭裂和正常共振的儿童相比,VPI组的内动脉段明显更长;与对照组和腭裂和正常共振的儿童相比,VPI组的外动脉段明显更短.
结论:这项研究的结果表明,在患有VPI的儿童中,LVP的功能节段的分布之间存在显着差异。在具有VPI的人群中,肌肉段的分布更为不利。
