目的 应用新型内镜鼻面罩提高因巨大胸骨后甲状腺肿造成气道梗阻病人在麻醉诱导、气管插管中的安全性。方法 插管过程中使用已获得专利授权的新型内镜鼻面罩进行清醒经口纤支镜引导下气管插管 结果 在纤支镜引导明视下气管插管一次成功，插管过程中病人无氧饱和度下降、呛咳等不良反应。结论 该新型内镜鼻面罩在困难气道气管插管中可以提高病人的安全性，有很高的临床应用价值。

Objective To elevate the safety of a airway obstructed patient caused by huge substernal goiter in anesthesia induction and tracheal intubation with a novel endoscopic nasal mask. Methods A novel endoscopic nasal mask was used in the process of awake oral fiberoptic bronchoscopy guided tracheal intubation. Results The first attempt of tracheal intubation was successful under the guide of bronchoscope without oxygen saturation decrease, cough and other adverse reactions. Conlcusion The novel endoscopic nasal mask could enhance patient safety in difficult airway intubation and with great clinical application value.
