title: [Quantitative evaluation of the focus range of juvenile onset recurrent respiratory papillomatosis].
abstract: OBJECTIVE
  To investigate the clinical application of quantitative evaluation of the focus range of juvenile onset recurrent respiratory papillomatosis (JO-RRP).
  
  
  METHODS
  Disease severity was scored as the sum of ratings of 1 (minimal), 2 (moderate), or 3 (severe) for involvement of 22 areas of the respiratory tract and digestive tract. Sixty-eight cases with JO-RRP patients underwent 238 procedures were removed papillomas. A Storz laryngoscope was used to exposed and suspend the larynx, and an endoscope video system was used to display the pathological changes.
  
  
  RESULTS
  The score of these cases range from 2 to 20, most of them range from 7 to 14. Papillomas were found in the larynx in each case, vocal cords and false vocal cords were the most common places involved. Nose, pharynx, hard palate, lung or esophagus involved was seldom found. The score declined as the patients underwent more procedures. It is in accord with the clinical characteristic of JO-RRP.
  
  
  CONCLUSIONS
  We concluded that our means of JO-RRP focus range quantitative evaluation could evaluate the severity and clinical curative effect objectively. It was a scientific and convenient way, and worth to be generalized.
