正常人群声门比例的测量研究

Study on the measurement of glottic proportion in subjects with normal larynx

目的:探究正常人群喉的声门比例(GP)及性别差异。方法:选择2017年1月-2019年12月在解放军总医院第六医学中心就诊的200例喉部结构正常的患者作为实验组,其中组1包括100例女性,组2包括100例男性;选择Pontes文章中的对照组60例,30例女性设为组3,30例男性设为组4。结果:组1的GP值为0.78~1.76,平均1.24;组2的GP值为0.82~2.20,平均1.37;组3的GP值为0.91~1.20,平均1.04;组4的GP值为1.07~1.44,平均1.21。统计分析4组数据均呈正态分布;组1、组2、组3、组4标准差分别为0.16、0.26、0.08和0.10,方差齐性检验P<0.05;采用Games-Howell检验进行多组分析,组1与组2,组3与组4,组1与组3,组2与组4,统计分析4对数据,结果均显示P<0.05,提示存在统计学差异。结论:从整体上看,男性组的GP均值大于女性,但不是所有男性GP值均大于女性;在高GP值区间内,男性占比大,在低GP值区间内,女性占比大。以往多将男性和女性作为两个整体,对喉部和声门进行分析,建议在探讨声门大小以及相关疾病时,更应该注重个体的差异性。

Objective:The aim of this study is to explore the glottic proportion(GP)and gender difference in Chinese subjects with normal larynx.Methods:Two hundred patients with normal larynx in Sixth Medical Center of PLA General Hospital from January 2017 to December 2019 were selected as the experimental group.Group 1 included 100 females and group 2 included 100 males.Sixty patients with normal larynx in the Pontes article were selected as the control group,including 30 females as group 3 and 30 males as group 4.Results:The GP range in group 1 was 0.78-1.76,with a mean of 1.24;0.82-2.20 in group 2,with a mean of 1.37;0.91-1.20 in group 3,with a mean of 1.04;1.07-1.44 in group 4,with a mean of 1.21.Statistical analysis showed that the data of the four groups were normal distribution,the standard deviation was 0.16 in group 1,0.26 in group 2,0.08 in group 3,0.10 in group 4,and the test of homogeneity of variance was P<0.05.Games-Howell test was used for multi-group analysis,including group 1 and group 2,group 3 and group 4,group 1 and group 3,group 2 and group 4.The statistical results of the four groups all showed P<0.05,indicating that there were statistical differences.Conclusion:On the whole,the average GP of male group was higher than that of female,but not all males have a greater GP value than females.In the range of high GP value,males accounted for a large proportion,while in the range of low GP value,females accounted for a large proportion.In the past,most articles regard men and women as two groups to study the glottic proportion,and it was suggested that more attention should be paid to individual differences when discussing glottic proportion and related laryngeal diseases.
