The long-term results of hyoid-sternohyoid grafts in the correction of subglottic stenosis.

The long-term follow-up of eight patients with established subglottic stenosis managed with a composite hyoid-sternohyoid graft is reported. Four of these patients were children. All but one of the patients were extubated within four months of surgery. The reconstructed airway is shown to grow with age and re-stenosis has not occurred. Apart from post-operative granulation tissue at the repair site, the major complication has been a breathy voice in two children due to overwidening of the larynx.
