Two cases of bifid epiglottis are presented: one with an associated laryngeal cyst and another with an associated cricoid stenosis. The occurrence of multiple laryngeal anomalies in association with bifid epiglottis has not previously been described. The occurrence of an extra digit is noted to be statistically significant both in the current series and in a review of the literature. A brief review of the embryologic classification and staging by the Carnegie System, and the correlation of the time sequence of development of the epiglottis is presented. No correlation is made as to the mechanism of the origin of this laryngeal anomaly, as adequate embryologic knowledge of the development of the pharynx is not available at this time.
一例伴有喉部囊肿，另一例伴有环状软骨狭窄。此前尚未描述过会厌裂合并多种喉部异常的情况。在本系列病例以及文献回顾中，额外手指的出现具有统计学意义。本文简要回顾了卡内基系统的胚胎学分类和分期，以及会厌发育的时间顺序相关性。由于目前尚无关于咽部发育的充分胚胎学知识，因此未对这种喉部异常的起源机制进行关联分析。
