腭隐裂患者头颅侧位X线片测量分析

目的　应用回顾性研究的方法对 50例腭隐裂患者X线片测量并与健康对照组对比分析 ,观察软腭在形态学、运动能力以及腭帆提肌附着位置等方面的特点 ,进一步研究腭隐裂患者腭咽闭合不全的原因 ,为其诊断提供依据。方法　腭隐裂患者 50例 (年龄 4～ 51岁 ,平均年龄 1 1 9岁 ,男性 2 0例 ,女性 30例 ,男∶女 =1∶1 5)。对术前头颅侧位定位X线片共 1 0 0张 (每例静止及发“i”音各 1张 )进行测量分析。结果　腭隐裂组的软腭相对长度较对照组短 ,患者的腭帆提肌附着点相对位置比对照组靠前 ,发音时软腭抬高角度较小 ,以上 3项指标经统计学分析 ,差异有显著性 (P <0 0 5)。两组间硬腭相对长度和发音时软腭伸长量的比较差异无显著性 (P >0 0 5)。结论　通过测量所得指标(包括软腭相对长度、腭帆提肌附着位置及发音时软腭抬高角度 )是诊断腭隐裂的重要指标

A study of lateral skull radiography of patients with submucous cleft palate

OBJECTIVE: To investigate the insertion position of the levator veli palatini in the soft palate with SMCP comparing normal group and find out reliance diagnosis methods for SMCP. METHODS: Experimental group: lateral skull radiography film were taken in 50 patients with SMCP at rest and "i" phonation. Five parameters were measured which are relative length of soft palate and hard palate; levatorveli palatini insertion in the soft palate; elongation and angle of soft palate when lifting up on phonation. Control group: Ten sets (rest and pronouncing "i") of lateral skull radiography were used as control group. X-rays were taken for ten normal subjects without speech disorder or other abnormal physical situations. All data were subjected to the t-test of statistical significance. RESULTS: The difference of measures between patients with SMCP and normal control was significant (P
