Many surgical procedures have been devised to manage laryngotracheal stenosis
secondary to trauma. Laryngotracheal atresia is the most severe form and
the most difficult to repair. The Meyer procedure is a three-stage operation
that provides structural support that is covered with mucosa. A laryngotracheal
trough is created and a carved trough-shaped cartilage graft is placed
above and lateral to it in the first stage. The skin over the graft is
replaced by buccal mucosa in the second stage. In the last stage, the cartilage
graft with overlying mucosa is swung onto the trough as a composite flap
replacing the anterior and lateral laryngeal and tracheal walls. Attempt
at reconstruction was made in 8 patients. All but one lesion was secondary
to endotracheal intubation. Two patients were unable to be taken to completion
of the third stage. Of the remaining 6 patients, all have a functional
voice and only 1 remains cannulated at night. |
