Objective: To investigate the feasibility of Selsctive cricothyroid laryngotomy instead of incision of trachea.

Results: Tracheotomy was applied in 171 cases, and cricothyroid laryngotomy was performed in 7 cases among these patients. The achievement ratio was 100%.

结果171例困难气管切开病例均成功进行气管切开术，其中环甲膜切开7例，气管切开成功率100%，无术中死亡病例发生。
