在老年人中，声带弯曲，临床上没有明显的器质性或功能性病变。本研究对64例年龄在70 ~ 104岁的正常人喉进行了组织学检查。结果表明：（1）男性声带弯曲程度随年龄增长而增加。2)声带固有层厚度的减少，尤其是浅层，是弓声的原因。3)甲杓肌和弓度之间没有明确的关系。4)老年性声带弯曲是一种老年性改变，可引起声门闭合不全，并由此引起嗓音障碍，至少是嗓音老化的病因之一。
In elderly people, vocal folds are bowed without clinically noticeable organic or functional lesions. In this study, histological examination of such bowing was made, using 64 normal human larynges, with ages ranging from 70 to 104 years old. The results were summarized as follows: 1) The degree of bowing of the vocal fold was found to increase with age in males. 2) Decrease in the thickness of the lamina propria, especially the superficial layer, of the vocal fold was the cause of bowing. 3) No definite relationship between the thyroarytenoid muscle and degree of bowing was determined. 4) Bowing of aged vocal folds was a geriatric change causing glottic incompetence with consequent voice disorders and was, at least, one of the etiologies of aging of the voice.
