[Hydroxyapatite for laryngotracheal framework reconstruction].

This paper reported combined sternohyoid myocutaneous flap and hydroxyapatite (HA) graft for laryngotracheal reconstruction in clinical and experimental studies. HA rings were employed for reconstructing the laryngotracheal framework in 10 patients on the base of animal experiment. The implant was well taken in all cases without any rejection, resulting in excellent airways. The study demonstrates that this procedure can be used in treatment of severe laryngotracheal stenosis.
