Use of Montgomery T-tube in laryngotracheal reconstruction in children: is it safe?

Abstract

Montgomery T-tubes are often used in adult patients; however, they are less commonly used in the pediatric age group. The purpose of this report is to describe our experience with this stent in pediatric laryngotracheal reconstruction. A retrospective chart review was performed to identify early and late complications. Nutritional assessments were made on the basis of weight percentile comparisons at the time of surgery and at the end of the stenting period. From 1990 to 1997, the Montgomery T-tube was utilized in 26 children undergoing 36 airway reconstruction procedures (21 laryngotracheoplasties and 15 cricotracheal resections). The upper limb of the tube extended above the level of the glottis in all patients. The patients ranged in age from 2.4 to 17.9 years. The duration of stenting ranged from 2 weeks to 23 months. Three patients (11.5%) had significant aspiration and did not improve following diet modifications and swallowing therapy, requiring tube feedings. One patient had postoperative subcutaneous emphysema that resolved spontaneously. Three patients required early removal of the stent due to an inability to tolerate plugging. Granulation tissue above the upper limb of the stent during the stenting period was noted after 6 laryngotracheal reconstruction procedures (16%). Only 1 patient fell off his growth curves during the period of stenting. There were no deaths in this series, and no emergent procedures were required. Postoperative and home care and management of complications are discussed. Our experience indicates that Montgomery T-tubes can be utilized relatively safely in children, providing that postoperative and home care are meticulous.
