Two sets of investigations were conducted with excised human larynges. The glottis was closely observed and photographed from above and below in three conditions: neutral, adduction, and abduction. The structure surrounding the posterior glottis was histologically investigated in the same three conditions. The results are as follows. The structure surrounding the posterior glottis consists of three portions: the posterior wall of the glottis, the lateral wall of the posterior glottis, and the cartilaginous portion of the vocal fold. During vocal fold adduction, the posterior part of the larynx closes completely not at the glottis but at the supraglottis, resulting in formation of a conic space in the posterior glottis that can be viewed only from below. The posterior glottis accounts for approximately 35% to 45% of the entire glottic length and 50% to 65% of the entire glottic area. The mucosa of the posterior glottis has ciliated epithelium. The lamina propria consists of two layers. The posterior glottis can be regarded as a respiratory glottis.
对切除的人体喉部进行了两组研究。在三种状态下从上方和下方对声门进行了密切观察和拍照：中立状态、内收状态和外展状态。在相同的三种状态下对声门后部周围的结构进行了组织学研究。结果如下。声门后部周围的结构由三部分组成：声门后壁、声门后部侧壁和声带的软骨部分。在声带内收期间，喉部后部并非在声门处而是在声门上完全闭合，导致声门后部形成一个仅从下方可见的锥形空间。声门后部约占整个声门长度的35%至45%以及整个声门面积的50%至65%。声门后部的黏膜有纤毛上皮。固有层由两层组成。声门后部可被视为呼吸性声门。
