The authors describe a technique of entry into the vallecula with the guide of a small Deaver retractor inserted transorally, beyond the tongue base, into the vallecula. The tip of the Deaver directs the surgeon to the pharyngotomy site and allows pharyngeal entry and access without damaging structures in the region. This technique is particularly useful in total laryngectomy with or without pharyngectomy and is applicable whenever entry to the pharynx through the vallecula is indicated.
作者描述了一种在经口插入的小型迪弗牵开器引导下进入会厌谷的技术，该牵开器经舌根插入会厌谷。迪弗牵开器的尖端引导外科医生找到咽切开部位，并允许进入咽部而不损伤该区域的结构。该技术在有或无咽切除术的全喉切除术中特别有用，并且在任何需要通过会厌谷进入咽部的情况下都适用。
