摘要
目的 探讨正常软腭的声像图特征。方法 经颏下超声观察 3 1例正常人的软腭解剖结构 ,测量软腭的厚度、长度、运动幅度。结果 冠状切面软腭呈一低回声带 ,纵断面软腭呈弧状 ,从硬腭骨性带状强回声与软腭的交界处延续到后方的游离缘。软腭的厚度为 ( 5 .4± 1.0 )mm ,长度 ( 4 3 .9± 6.7)mm ,运动幅度 ( 7.4±0 .8)mm。结论 经体表超声观测软腭的解剖结构及活动度是一种重复性好、测量准确的方法 。
Objective To investigate sonographyic characteristics of normal soft palata.Methods The soft palate of thirty one healthy volunteers were observed by ultrasonography in submaxillary region.The thickness,length and movement of soft palate were measured.Results Soft palate was found as a hypoecho strip by coronary scan and a arc from the combination of hard palate and soft palate to the free margin of soft palate in longitudinal section.Thickness of soft palate was ( 5.4 ± 1.0 )mm, length ( 43.9 ± 6.7 )mm,movement ( 7.4 ± 0.8 )mm respectively.Conclusions The observation of anatomical structure and movement of soft palate by ultrasonic examination is helpful to the evaluation of the velopharyngeal insufficiency after cleft palate repair,which is an accurate and repeated method.
