An investigation was carried out to determine the location of the preepiglottic space (PES) and its relationship to the paraglottic space (PGS). Excised human adult larynges served as materials for this study. The distribution of the PES of the larynx was determined histologically in 3 whole organ serial sections: sagittal, horizontal, and coronal. The results are summarized as follows. 1) The PES exists not only anterior, but also posterolateral and inferolateral to the epiglottis. 2) Its posterior end is located in the vicinity of the anteroposterior midpoint of the thyroid lamina. 3) The PES is adjacent to the PGS posteroinferiorly and is separated by fibrous tissue (the thyroglottic ligament). Posterosuperiorly, the 2 spaces are not clearly delineated from each other.
开展了一项研究以确定会厌前间隙（PES）的位置及其与声门旁间隙（PGS）的关系。切除的成人喉部作为本研究的材料。通过对3个全器官连续切片（矢状面、水平面和冠状面）进行组织学检查来确定喉部PES的分布。结果总结如下。1）PES不仅存在于会厌前方，还存在于会厌的后外侧和下外侧。2）其后端位于甲状软骨前后中点附近。3）PES在下方与PGS相邻，并由纤维组织（甲状舌骨韧带）分隔。在上方，这两个间隙彼此分界不清。
