The main purpose of the study is to observe the effect of plasm radiofrequency at low temperature in treatment of chronic rhinitis on nasal airway resistance (NAR).
Using active anterior rhinomanometry, NAR were measured in eighty two patients who suffered from chronic rhinitis before and postoperation. The subjective impression of their nasal patency was assessed using a 10-pointscale.
The NAR was (0.665 +/- 0.21) kPa /(s x L) before operation and (0.301 +/- 0.16) kPa/(s x L) three months after operation. The NAR was (0.391 +/- 0.24) ten months after operation. The differences were statistically significant (P < 0.01) between the NAR before and postoperation. There were significant differences in the subjective impression of patients' nasal patency as well (P < 0.01).
Plasm radiofrequency at low temperature in treatment of chronic rhinitis is effective in decreasing NAR and improving the subjective impression of their nasal patency.
本研究的主要目的是观察低温等离子射频治疗慢性鼻炎对鼻气道阻力（NAR）的影响。
采用主动前鼻测压法，对82例慢性鼻炎患者手术前后的鼻气道阻力进行测量。使用10分制评估患者对鼻腔通畅程度的主观感受。
术前鼻气道阻力为（0.665±0.21）kPa/（s·L），术后3个月为（0.301±0.16）kPa/（s·L），术后10个月为（0.391±0.24）kPa/（s·L）。手术前后鼻气道阻力差异有统计学意义（P<0.01）。患者鼻腔通畅程度的主观感受也有显著差异（P<0.01）。
低温等离子射频治疗慢性鼻炎可有效降低鼻气道阻力，改善患者鼻腔通畅程度的主观感受。
