有资料表明,老年人的喉解剖发生了改变,声带弹性纤维变少,软骨钙化失去弹性,喉肌肉萎缩松弛,声带由于脂肪减少而失去色泽。本文通过联合声门描记,研究解剖学的改变对喉振动周期运动的影响。10名60岁以上(平均71.7岁)的男性为研究对象,以10名25岁以下(平均22.3岁)的男性为对照。统计出两组中的开放商数(OQ)和速度商数(SQ)。0Q在青年组为0.548,在老年组为0.543,P=0.67,两组没有显著差别。SQ在青年组为0.551,在老年组为0.919,P=0.027,老年
Data show that the elderly laryngeal anatomy has changed, fewer vocal cord elastic fibers, cartilage loss of elasticity, laryngeal muscle atrophy relaxation, the vocal cords lose color due to reduced fat. In this paper, we study the effects of anatomical changes on the laryngeal vibrational movements by joint glottis. Ten men over the age of 60 (mean, 71.7 years old) were selected as study subjects, and 10 men under 25 (average 22.3 years old) were used as controls. Statistics open quotient (OQ) and speed quotient (SQ) in two groups. 0Q in the young group was 0.548, 0.543 in the elderly group, P = 0.67, no significant difference between the two groups. SQ was 0.551 in the youth group, 0.919 in the elderly group, and P = 0.027 in the elderly
