title: Effectiveness of topically applied halofuginone in management of subglottic stenosis in rats.
abstract: OBJECTIVE
  The aim of the study is to ascertain the antifibrotic effect of topically applied halofuginone after acute subglottic injury.
  
  
  METHODS
  After standardized trauma to subglottic area, rats were divided into two groups: the study group that received treatment and the control group that did not. The subjects were treated with topical application of cottonoid soaked in 30 mg/dL halofuginone solution for 5 minutes after subglottic trauma. The larynx specimens were examined histopathologically by light microscopy to assess fibrosis, epithelialization, inflammation, and necrosis.
  
  
  RESULTS
  The fibrosis indexes of the treated group were significantly less than those of the control group (P < 0.05).
  
  
  CONCLUSIONS
  Topically applied halofuginone hydrobromide decreases fibrosis/scar tissue formation secondary to experimentally induced acute subglottic trauma.
