Controversial opinions on the existence of a "barrier" between the supraglottic and glottic regions of the larynx are reported. Even if the two areas have different embryological derivations, there is no anatomic evidence of a "barrier" that could prevent supraglottic cancer from extending downward to the glottis. Numerous adequate pathologic studies, including whole organ sections, confirm that for advanced cancers, anatomic compartments delimiting the spread of the neoplastic process from the supraglottis to the glottis do not exist. Therefore, supraglottic laryngectomy should be performed not on the basis of embryological considerations, but on the basis of the actual extension of the neoplastic lesion.
关于喉声门上区和声门区之间存在“屏障”的观点存在争议。即使这两个区域有不同的胚胎学起源，但没有解剖学证据表明存在“屏障”可阻止声门上癌向下蔓延至声门。包括全器官切片在内的众多充分的病理学研究证实，对于晚期癌症，并不存在界定肿瘤过程从声门上区蔓延至声门的解剖学腔室。因此，声门上喉切除术不应基于胚胎学考虑，而应基于肿瘤病变的实际范围来进行。
