腭隐裂患者头颅侧位X线片测量分析

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

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 )

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 be tween patients with SMCP and normal control was significant( P ≤0 05). Conclusion It was obvious that both absolute and relative length of soft palate are short and levator muscle insert into soft palate arterially in patients with SMCP comparing with normal group,which caused VPI and become one of the criterias for SMCP.[
