              stage in the observation group were lower than those in the corresponding control group,and the difference was statistically significant
             (P < 0.05). There was no statistical significance in the postoperative complications of patients with T2+T3,T2 and T3 stage in the
              observation group compared with the corresponding control group(P > 0.05). The postoperative recurrence rate of patients with T2+T3
              and T3 stage in the observation group was lower than that of the control group,with statistical significance(P < 0.05),while the
              postoperative recurrence rate of patients with T2 stage in the observation group was lower than that of the control group,with no
              statistical significance(P > 0.05). Conclusion:Low temperature plasma radiofrequency ablation under nasal endoscope can treat
              Krouse T2 and T3 stage NIP and its base under a clear surgical field of view. It has the advantages of less intraoperative blood loss,
              shorter length of hospitalization,less pain and lower recurrence rate,compared with routine operation. And it has satisfactory clinical
              efficacy,which is worthy of popularization and application.
