Treatment of traumatic laryngotracheal stenosis with a self-made laryngeal dilator

Objective To study the treatment effect of self-made laryngeal dilator in treatment of traumatic laryngotracheal stenosis and investigate the dwell duration of the laryngeal dilator. Methods A total of 62 cases of traumatic laryngotracheal tenosis were divided into two groups, ie, first group (52 cases, treated with the laryngeal dilator for the first time) and second group ( 10 cases, treated with the laryngeal dilator again after the failure in the first operations). In laryngotrachectomy, scar tissue was resected as much as possible and the laryngeal dilator placed in laryngeal cavity. Results Cases in the first group were decannulated 9-12 months after operation and could breathe freely, speak well and work. Laryngotracheal tenosis recurred 3-4 months after decannulation in the cases in the second group that was treated with the laryngeal dilator again and decannulated successfully. During the stenting time, no serious complications such as airway obstruction happened. The follow-up for 1-10 years showed no laryngotracheal tenosis recurrence. Conclusions The laryngeal dilator is made simply and conveniently and can win satisfactory outcome in treatment of laryngotracheal stenosis without reject reaction. The stenting time should be more than 9-12 months.
