Conjoint hyoid bone segments for the repair of severe laryngeal stenosis.

We discuss and show by illustrations a surgical technique for the management of severe combined laryngeal and subglottic stenosis using multiple pieces of hyoid bone. No serious problems resulted from the removal of the entire hyoid bone. All patients have maintained a good airway, despite the possibility of absorption of a free bone graft. Although it is reasonable to try to use the hyoid bone with a strap muscle pedicle, it is impossible to reconstruct the subglottic and laryngeal area without multiple pieces. Our experience encourages us to use multiple pieces of free hyoid bone for laryngotracheal reconstruction.
