title: [Clinical use of acoustic rhinometry guiding radiofrequency to treat nasal obstruction].
abstract: OBJECTIVE
  To investigate the value of acoustic rhinometry in treating patients with nasal obstruction by radiofrequency(RF).
  
  
  METHODS
  The clinical results of 46 nasal obstruction cases treated by RF were analyzed. The therapy area were determined by acoustic rhinometry.
  
  
  RESULTS
  Pretherapy: mean nasal cross-sectional area (NMCA) (0. 37+/-0. 16)cm(2) , the front part of inferior nasal concha minimal cross-sectional area (MCA) (1. 10+/-0. 17)cm(2) , volume of nasal cavity(NV) (5. 76 +/-2. 81) cm(3), nasal resistance(NR) (5. 96 +/- 2. 24) kPa x s/L. Post therapy: NMCA(0. 68+/-0. 18)cm, MCA(1. 76+/-0. 19)cm(2), NCV (9. 10+/-2. 10)cm(3), NR(2. 42+/-0.86) kPa x s/ L. For 46 cases, there were remarkable improvements between pretherapy and post therapy ( P <0. 05). Twenty-seven cases were cured, 19 cases were improved, total effectiveness rate were 100%.
  
  
  CONCLUSIONS
  RF therapy guided by acoustic rhinometry may help determine the therapy area and improve the effectiveness.
