Objective: To discuss the long-term results of the laryngotracheal (LT) reconstruction with a composites stohyoid myocutaneous rotary door flap (RDF) and hydroxylapatite (HA) ring. Methods:Thirty-two patients suffered by LT stenosisn were treated through LT reconstruction with a composite stohyoid myocutaneous RDF and HA ring, then we made long-term follow up. Results :Thirty of the 32 patients were successfully decannulated from 1 to 6 months postoperatively and the decannulation rate was 93% (30/32). Decannulated failed in 2 patients because of hypertrophic scar and infection in the operative region. The term of follow-up ranged from 1 to 10 years in 30 patients. patients had a stable airway and an effective voice. Conclusion: A composite stohyoid myocutaneous RDF and HA ring is a relatively simple method with positive long-term effect for LT reconstruction.
