Iatrogenic subglottic tracheal stenosis after tracheostomy and endotracheal intubation: A cohort observational study of more severity in keloid phenotype.

Our study suggests that tracheostomized patients with keloid phenotype are more susceptibility to develop iatrogenic tracheal stenosis of greater severity and with poorer treatment outcome. Greater cautions may be required when performing tracheostomy in keloid subjects. More substantive analysis is warranted to establish keloid phenotype as a risk factor for tracheal stenosis.
