The simultaneous occurrence of laryngocele and laryngeal cancer is uncommon. To date, 64 detailed descriptions of this association have appeared in the world's literature. In large restrospective series of laryngeal cancers, the incidence varies between zero and 9.7 per cent. Four additional cases are discussed. The pathogenesis of laryngoceles associated with tumor appears to be related to factors altering the mechanics of the laryngeal ventricle to a chronically elevated intralaryngeal pressure. Circumstances producing a ball valve effect appear to be a factor for saccular distention in some cases. In other instances, the association between laryngocele and cancer is probably coincidental.
喉膨出与喉癌同时发生的情况并不常见。迄今为止，世界文献中已出现64例关于这种关联的详细描述。在大型喉癌回顾性系列研究中，其发病率在0至9.7%之间。本文讨论另外4例病例。与肿瘤相关的喉膨出的发病机制似乎与改变喉室力学从而导致喉内压长期升高的因素有关。在某些情况下，产生球阀效应的情况似乎是囊状扩张的一个因素。在其他情况下，喉膨出与癌症之间的关联可能是巧合。
