解剖学术语

喉前庭(laryngeal vestibule)即是声带上方的腔部分;其基部或前壁呈现出三角形宽广之形状,而其中心部即会厌结节(楔形结节英语cuneiform tubercle小角结节英语corniculate tubercle)的"后突"(backward projection)处。喉前庭包含前庭襞,在前庭襞与声带之间即是喉室英语Laryngeal ventricle[1]

进一步解剖、喉前庭即是喉部侧壁上的开口部分,介于前庭襞上方与声带下方之间。它是喉部侧壁到喉室英语laryngeal ventricle的入口。另一面视之、喉前庭即从会厌侧壁延伸到覆有黏膜杓状软骨前庭韧带(vestibular ligament)所构成之部分。而声带即是覆有黏膜之环甲韧带上半部多出的边缘部分。再而环甲韧带(conus elasticus)或其侧韧带即是环甲膜侧向增厚之部分。
