The fourth branchial pouch sinus (FBPS) is a rare translaryngeal anomaly with diverse manifestations, including neonatal stridor and recurrent deep neck infection. Review of the world literature reveals 23 reports of sinuses consistent with fourth pouch origin. We present two additional cases, including the only example of a right-sided FBPS. Retrograde excision, beginning at the piriform apex, ensures complete removal of the tract and protection of the recurrent nerve. The posterior border of the thyroid ala must be resected or retracted for adequate exposure. Failure to remove the translaryngeal portion of the tract almost guarantees recurrence.
第四鳃裂窦道（FBPS）是一种罕见的经喉异常，有多种表现，包括新生儿喘鸣和复发性深部颈部感染。对世界文献的回顾显示有23例符合第四鳃裂起源的窦道报告。我们又报告了2例，包括唯一一例右侧FBPS。从梨状窝尖开始逆行切除，可确保完整切除窦道并保护喉返神经。必须切除或牵开甲状腺叶的后缘以获得充分暴露。未能切除窦道的经喉部分几乎肯定会复发。
