Abstract:
Twenty-seven children with varying degrees of laryngotracheal stenosis were treated at Texas Children's Hospital (TCH) from January 1984 to January 1989. Nineteen children had a residual airway demonstrable preoperatively, and following laryngotracheoplasty, 18 (95%) were successfully decannulated; all but 1 had a normal voice. Eight children had complete stenosis. Of these children, 6 could be decannulated, but 3 required a second laryngotracheoplasty. Four children now have voice abnormalities.
