Clinical Trial Summary

Laryngomicrosurgery requires deep paralysis and general anesthesia to finish the procedure. After the procedure, patients need a long time to recover. In the present study, with the support of the transnasal humidified rapid-insufflation ventilatory exchange, laryngomicrosurgery would be finished under nonintubated deep paralysis (NIDP) general anesthesia. In this case series study, the investigators will test the safety and feasibility of such a technique.
