The aim of this study is to explore the glottic proportion（GP） and gender difference in Chinese subjects with normal larynx. 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. 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 <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 <0.05, indicating that there were statistical differences. 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.
本研究旨在探讨中国正常喉部受试者的声门比例（GP）及性别差异。选取2017年1月至2019年12月解放军总医院第六医学中心的200例正常喉部患者作为实验组。第1组包括100名女性，第2组包括100名男性。选取Pontes文章中的60例正常喉部患者作为对照组，其中30名女性为第3组，30名男性为第4组。第1组的GP范围为0.78 - 1.76，平均为1.24；第2组为0.82 - 2.20，平均为1.37；第3组为0.91 - 1.20，平均为1.04；第4组为1.07 - 1.44，平均为1.21。统计分析显示，四组数据呈正态分布，第1组标准差为0.16，第2组为0.26，第3组为0.08，第4组为0.10，方差齐性检验<0.05。采用Games-Howell检验进行多组分析，包括第1组和第2组、第3组和第4组、第1组和第3组、第2组和第4组。四组统计结果均显示<0.05，表明存在统计学差异。总体而言，男性组的平均GP高于女性组，但并非所有男性的GP值都大于女性。在高GP值范围内，男性占比大，而在低GP值范围内，女性占比大。过去，大多数文章将男性和女性作为两组来研究声门比例，建议在讨论声门比例及相关喉部疾病时应更多关注个体差异。
