With the aid of high-speed cineradiography (up to 100 frames per second) the closure of the laryngeal vestibule during deglutition was studied in 150 volunteers free from swallowing complaints. The closure was observed to be effected by a peristaltic-like wave from below. This was accomplished in two steps. First the caudal segment of the vestibule, the supraglottic space, was closed by an apposition of the side walls. Then the cranial segment of the vestibule, the supraglottic space, was closed by an apposition of the fixed part of the epiglottis to the arytenoid region. The subdivision of the vestibule was made by an imaginary plane between the interarytenoid incisure and incisure of the thyroid cartilage. This subdivision corresponds to the location of the thyroarytenoid muscles lateral to the supraglottic space and the thyroepiglottic muscles lateral to the subepiglottic space. In this way the two muscle pairs contribute indifferent and distinct ways to the closure of the vestibule during deglutition.
借助高速电影造影术（每秒高达100帧），对150名无吞咽问题的志愿者吞咽时喉前庭的关闭情况进行了研究。观察到关闭是由下方类似蠕动的波实现的。这分两步完成。首先，前庭的尾段，即声门上间隙，通过侧壁的贴合而关闭。然后，前庭的头段，即声门上间隙，通过会厌的固定部分与杓状软骨区域的贴合而关闭。前庭的细分是通过杓间切迹与甲状软骨切迹之间的假想平面进行的。这种细分对应于声门上间隙外侧的甲杓肌和声门下间隙外侧的甲状会厌肌的位置。通过这种方式，这两对肌肉在吞咽过程中以前庭关闭的不同且独特的方式发挥作用。
