摘　　要：目的通过对喉部活动度进行测量,进一步精确勾画喉外扩靶区,以实现肿瘤精确放疗提高放疗效果。方法选取51例肿瘤患者为研究对象,通过CT测量喉部在四个方向最大活动度,通过spss23.0对实验所得数据进行统计分析。结果51位研究对象平均前联合向上最大移动范围为(13.04±6.72)mm,前联合向下最大移动范围为(1.53±2.41)mm,前联合向左最大移动范围为(1.44±1.74)mm,前联合向右最大移动范围为(1.35±2.27)mm,前联合向前最大移动范围为(3.81±2.74)mm,前联合向后最大移动范围为(0.75±1.59)mm,左侧甲状软骨板最大外移为(0.70±1.21)mm,左侧甲状软骨板最大内移为(1.86±2.85)mm,右侧甲状软骨板最大外移为(0.70±1.35)mm,右侧甲状软骨板最大内移为(1.42±1.71)mm,杓前角最大间距为(14.15±3.51)mm。以第一次测量为准确测量值,第二次、第三次测量值与第一次测量值差值绝对值为误差值,比较两次测量误差值。两次测量误差间差异无统计学意义(P>0.05)。≤60岁研究对象与>60岁研究对象的喉部活动度无显著性差异(P>0.05)。男性杓前角最大间距为(15.32±4.72)mm,显著高于女性的(12.14±1.61)mm,差异具有统计学意义(P<0.05)。转移的研究对象左侧甲状软骨板最大内移为(2.36±2.11)mm,显著高于未转移的(1.19±1.73)mm,差异具体统计学意义(P<0.05)。性别与前联合向上最大移动范围、杓前角最大间距呈现显著负相关(P<0.05),与左侧甲状软骨板最大外移呈显著正相关(P<0.05);年龄与前联合向上最大移动范围呈显著正相关(P<0.05),与前联合向下最大移动范围、左侧甲状软骨板最大外移呈显著负相关(P<0.05)。皮尔逊相关性分析发现甲状软骨板前联合向左移动度与左侧甲状软骨板最大外移具有显著正相关性(r=0.301,P=0.032);甲状软骨板前联合向右移动度与右侧甲状软骨板最大外移具有显著正相关性(r=0.072,P=0.000)。结论自然吞咽会引起喉�Objective Through the measurement of laryngeal motion,the target volume of laryngeal expansion was further accurately delineated,so as to achieve precise radiotherapy and improve the radiotherapy effect.Methods A total of 51 tumor patients were selected as the research objects.The maximum motion of larynx in four directions was measured by CT,and the experimental data were statistically analyzed by SPSS23.0.Results The average maximum movement range of the 51 subjects was(13.04±6.72)mm upward,(1.53±2.41)mm downward,(1.44±1.74)mm leftward,(1.35±2.27)mm rightward,(3.81±2.74)mm forward and(0.75±1.59)mm backward,The maximum outward displacement of the left thyroid cartilage plate was(0.70±1.21)mm,the maximum inward displacement of the left thyroid cartilage plate was(1.86±2.85)mm,the maximum outward displacement of the right thyroid cartilage plate was(0.70±1.35)mm,the maximum inward displacement of the right thyroid cartilage plate was(1.42±1.71)mm,the maximum distance between the anterior angles of the dipper was(14.15±3.51)mm,the left and right measurement errors were(1.46±1.32)mm,and the front and rear measurement errors were(2.72±1.92)mm.The upper and lower positioning errors are(0.26±0.19),the front and rear positioning errors are(0.29±0.22),and the left and right positioning errors are(0.39±0.27).There was no significant difference in laryngeal activity between subjects≤60 years old and those>60 years old(P>0.05).The maximum distance between male and female anterior angles was(15.32±4.72)mm,which was significantly higher than that of female(12.14±1.61)mm(P<0.05).The maximum inward displacement of the left thyroid cartilage plate of the metastatic subjects was(2.36±1.19)mm,which was significantly higher than that of the non metastatic subjects(1.19±1.73)mm,with specific statistical significance(P<0.05).Gender was negatively correlated with the maximum range of anterior commissure upward movement and the maximum distance between anterior angles of arytenoids(P<0.05),and positively correlate
