Does tracheostomy in children retard the growth of trachea or larynx?

Tracheostomy in children has been reported to cause tracheal stenosis, laryngeal stenosis and subsequent difficulties in decannulation. No long term follow-up studies appear to be in the literature describing the events following decannulation. This study compared the radiological size of the cricoid and tracheal lumens with that of normals. Except in special cases tracheostomy did not affect the subsequent growth of the trachea or cricoid. It is suggested that traumatic tracheal narrowing in children should be managed conservatively.
