OBJECTIVE: The aim of the study is to ascertain the antifibrotic effect of topically applied halofuginone after acute subglottic injury.
MATERIALS AND 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.
