title: [A clinical study of the acoustic rhinometry in nasal and nasopharyngeal airway of children with adenoid vegetation].
abstract: OBJECTIVE
  To investigate the significance of the AR measurement in diagnosis of adenoid vegetation and evaluation of the efficiency of adenoidectomy.
  
  
  METHODS
  Twenty-three healthy children and 27 children with adenoid vegetation were studied by ECCOVISION acoustic rhinometry (AR).
  
  
  RESULTS
  Tthe NAR of the in-patients before adenoidectomy [(0.44 +/- 0.17) kPa x L(-1) x min(-1)] were significantly (P < 0.05) greater than that of the healthy children [(0.33 +/- 0.17) kPa x L(-1) x min(-1)],while the total NPV [(14.74 +/- 5.01) cm3] were significantly (P < 0.01) smaller [(19.77 +/- 5.77) cm3]. The NAR of the in-patients after adenoidectomy [(0.36 +/- 0.21) kPa x L(-1) x min(-1)] were significantly (P < 0.05) smaller than that before adenoidectomy. The total NPV [(17.93 +/- 4.56) cm3] were significantly (P < 0.05) greater than that before adenoidectomy.
  
  
  CONCLUSIONS
  AR has significant importance in diagnosis of adenoid vegetation and it is also an efficient method to evaluate the efficiency of adenoidectomy.
