目的：探讨支撑喉镜喉显微外科手术与麻醉的关系。方法：回顾分析８４例于全麻支撑喉镜下显微外科手术的麻醉情况。结果：８４例均完整切除喉部病灶。环甲膜穿刺组２例穿刺针滑脱，气管插管组和塑料喷射管组未发生并发症。结论：塑料喷射管经鼻置入声门下喷射通气优于环甲膜穿刺和气管插管麻醉，安全、方便、操作简单、并发症少。
Objective: To investigate the relationship between laryngoscope laryngeal microsurgery and anesthesia. Methods: A retrospective analysis of 84 cases of anesthesia under general anesthesia with laryngoscope microsurgery was performed. Results: 84 cases were completely removed laryngeal lesions. There were no complications in 2 cases of cricothyroid membrane puncture needle slippage, tracheal intubation group and plastic injection tube group. Conclusion: It is safe, convenient and easy to operate with less complications because the plastic injection tube is superior to cricothyroid membrane puncture and endotracheal intubation for anesthesia.
