title: [The relationship between tracheotomy and intra-tracheal papilloma progression in children].
abstract: OBJECTIVE
  To clarify the relationship between tracheotomy and intra-tracheal papilloma progression and introduce the experience of managing dyspnea in the hospital.
  
  
  METHODS
  Children who were treated in ENT department of Tongren Hospital between 1992 and 1997 were reviewed in this essay. There were totally sixty-two children (thirty-two boys and thirty girls) with laryngeal papilloma and recurrent respiratory papillomatosis enroled in the series.
  
  
  RESULTS
  Among 33 non-tracheotomied children the intra-tracheal lesions were found in only 2 cases (6.1%). There were 17 (80.9%) cases presented intra-tracheal lesions in 21 tracheotomied cases, and it showed great statistical difference (chi 2 = 27.4, P < 0.005). There were no difference of onset age, sex and the first sites of papilloma lesions between the non-tracheotomied and tracheotomied groups(P > 0.05).
  
  
  CONCLUSIONS
  We found papilloma has a week potential to progress into trachea. Tracheotomy is the most important factor of intra-tracheal papilloma progression in many cases. The tracheotomy can be avoided.
