摘要
目的通过数字化影像,研究正常人发高元音"i"时软腭的形态,为腭裂修复的研究提供参考。方法对27例正常人发高元音"i"时的数字化头影侧位片进行分析,观察软腭在发音时的影像特点,测量发音时软腭竖直部分的长度,分析不同性别组间的差异。结果正常人发高元音"i"时,软腭呈膝盖状,可大致分为水平和竖直两部分。男性软腭竖直部分长度为(24.92±2.03)mm,女性软腭竖直部分长度为(20.66±2.77)mm,不同性别组间软腭竖直部分长度的差异有统计学意义(P<0.001)。结论在数字化头影侧位片中,正常人发高元音"i"时软腭形态类似,男性软腭竖直部分长度大于女性。
Objective To investigate the morphology of the soft palate in normal individuals with digital radiography,when they pronounced the high vowel of "i",and to provide the references for therapy of the cleft palate.Methods In this study,the sample comprised 27 normal subjects.With the digital cephalometry,the morphology of the soft palate when pronouncing the high vowel of "i" was observed.And the dimensional difference of the soft palate when pronouncing between different gender was studied.Results When pronouncing the high vowel of "i",the morphology of the soft palate was like the shape of the knee.And it could be divided into two parts: Horizontal and vertical.The length of the vertical part in male group was(24.92±2.03) mm,the length of the vertical part in the female group was(20.66±2.77) mm.The length of the vertical part was different between male and female group(P0.001). Conclusion The morphology of the palate when pronouncing the high vowel of "i" is similar.And the velar length of the vertical part of the male is longer than the female.
