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

ABSTRACT:

Background

Tracheostomy and endotracheal intubation can result in subglottic tracheal stenosis, and predisposition to keloid scar formation can increase stenosis risk after tracheal injury. This study aims to compare the incidence and severity of subglottic tracheal stenosis in keloid and non-keloid patients following iatrogenic tracheal injury, in particular tracheostomy.

Methods

From 2012 to 2017, 218 573 patients were intubated for surgery; 2276 patients received tracheostomy in People's Hospital of Zhengzhou University, China. Among these patients, 133 patients, who developed tracheal stenosis after intubation and/or tracheostomy, were divided into keloid or non-keloid groups; their Myer and Cotton grading of tracheal stenosis, time-to-onset of airway stenosis, and treat
