Sternohyoid myo-osseous flap for acquired subglottic stenosis in children

Endotracheal intubation can occasionally result in acquired subglottic stenosis (ASGS) in infants and children. Twenty-one consecutive patients, ages 3 months to 13 years, with ASGS secondary to endotracheal intubation and severe enough to require tracheotomy, are reviewed. Of this population, eight cases of ASGS were refractory to endoscopic excision and dilatation. These eight patients, five of whom had complete stenosis, underwent subglottic reconstruction using a sternohyoid myo-osseus flap. Six of the eight patients had been successfully decannulated with no evidence of recurrent stenosis at the time of this report.
