Sci Rep:骨传导 - 股骨牵引成骨术治疗唇腭裂患者中面生长的影像学研究

经腭缝牵张成骨术(TSDO)促进唇腭裂(CLP)患者中面部发育不良的中面生长。治疗后浅表骨骼变化显示中段骨骼的旋转进展与每个节段的不同位移相关,但报告很少关注内部结构的变化,包括环状缝线,上颌结节和上颌窦,这可能在这个过程中起关键作用。本研究评估了26例接受骨源性TSDO治疗的CLP患者的计算机断层扫描(CT)图像。结果显示,最突出的新骨形成发生在翼上颌骨缝合处并向前推动P点。由于上颌结节的生长,

经腭缝牵张成骨术(TSDO)促进唇腭裂(CLP)患者中面部发育不良的中面生长。治疗后浅表骨骼变化显示中段骨骼的旋转进展与每个节段的不同位移相关,但报告很少关注内部结构的变化,包括环状缝线,上颌结节和上颌窦,这可能在这个过程中起关键作用。本研究评估了26例接受骨源性TSDO治疗的CLP患者的计算机断层扫描(CT)图像。

结果显示,最突出的新骨形成发生在翼上颌骨缝合处并向前推动P点。由于上颌结节的生长,上颌第一磨牙与P点相比表现出显着更大的进展。上颌结节进展和P点对上颌第一磨牙的贡献率值在UCLP中分别为26%和74%,在BCLP中分别为25%和75%。此外,上颌窦体积也显着增加。

总之,骨传导TSDO治疗的中面生长取决于主要在翼上颌骨缝线中的缝合骨形成促进的二次移位和上颌结节和上颌窦体积的增长引起的一次移位。
