目的观察射频等离子消融术治疗上呼吸道阻塞性疾病的疗效。方法利用射频等离子消融术治疗 4 4例上呼吸道阻塞性疾病 ,观察治疗前、后临床症状的变化。结果治疗后 5～ 7天 ,呼吸道阻塞性症状明显改善 ,2～ 3周复查时见射频治疗局部伪膜已全部脱落 ,咽腔及鼻腔较术前明显宽畅 ,粘膜光滑。平均住院 5～ 7天。结论射频等离子消融术治疗上呼吸道阻塞性疾病 ,显示出一定的优越性、有效性和较轻的副作用。 Objective To observe the effect of radiofrequency plasma ablation on upper airway obstructive disease. Methods Radio frequency plasma ablation was used to treat 44 cases of upper respiratory tract obstructive diseases. The changes of clinical symptoms before and after treatment were observed. Results 5 to 7 days after treatment, obstructive respiratory symptoms improved significantly, 2 to 3 weeks to review the radio frequency treatment of partial pseudomembranous all have been shed, the pharynx and nasal cavity was significantly wider than the preoperative smooth, mucosal smooth. The average hospital stay of 5 to 7 days.
