title: [Analysis of treatment failure in pediatric subglottic stenosis].
abstract: BACKGROUND
  The good results obtained until nowadays in the surgery of subglottic stenosis is followed by an analysis of the failures.
  
  
  METHODS
  We study retrospectively 48 cases treated in the last eight years in two institutions. Study variables were: age, previous diagnosis, grade os the stenosis, surgical treatment, complications and evolution.
  
  
  RESULTS
  Mean age was 2.8 +/- 0.43 years (newborn-17 years). In 13 cases (27%) the result obtained was considered a failure. Failure indexes were: treatment selection (7,7%), surgical technique selection (23%), due to the technique itself (23%), iatrogenia (15,4%), associated diseases (30,7%). Mortality of the series was 8.3%.
  
  
  CONCLUSIONS
  The learning curve of these techniques is difficult although once the necessary experience is achieved the results are excellent.
