title: [The effect of plasm radiofrequency at low temperature in treatment of chronic rhinitis on nasal airway resistance].
abstract: OBJECTIVE
  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).
  
  
  METHODS
  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.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  Plasm radiofrequency at low temperature in treatment of chronic rhinitis is effective in decreasing NAR and improving the subjective impression of their nasal patency.
