[Reconstruction of laryngotracheal stenosis: experience of twenty years].

In order to improve the curative effects of laryngotracheal stenosis, 261 patients treated for laryngotracheal stenosis during the last twenty years were retrospectively reviewed. Glottic reconstruction, fence-form laryngotracheal reconstruction and laryngotracheotomy with autogenous tissue or hydroxylapatite rings were selectively used for one-stage reconstruction. Our results demonstrated that among 261 patients, 9 failed in decannulation, 5 were lost for follow-up, 247 (94.6%) patients were successfully decannulated. Among 192 patients followed-up from 1 to 18 years, 4 had restenosis 3 years after operation, 3 were successfully retreated and 10 failed. 182 (94.7%) patients had stable airways. It is concluded that there was no fixed treatment for laryngotracheal stenosis. The choice of surgical procedure and grafting must be decided on the pathologic condition of the larynx and trachea. The advantages of fence-form laryngotracheal reconstruction are simple technique and good result. Reconstruction with combined bipedicled myocutaneous flap and costal cartilage or artificial materials are better for severe laryngotracheal stenosis and large tracheal defect. The usage of stent is important for laryngotracheal reconstraction.
