上呼吸道阻塞性疾病多由上呼吸道解剖性狭窄及局部软组织增生或塌陷性增强引起。低温双极射频消融治疗系统又称等离子刀,治疗上呼吸道阻塞性疾病具有优越的射频消融效应。2002年1月～2005年12月,我们应用低温等离子射频消融术(RFA)治疗上呼吸道阻塞性疾病147例,疗效满意。现分 Upper airway obstructive disease and more by the upper respiratory tract anatomical stenosis and local soft tissue hyperplasia or collapse caused by enhancement. Low temperature bipolar radiofrequency ablation treatment system, also known as plasma knife, for the treatment of upper respiratory tract obstruction has excellent radiofrequency ablation effect. From January 2002 to December 2005, we applied 147 cases of upper respiratory tract obstructive disease by low temperature plasma radio frequency ablation (RFA), and the results were satisfactory.
