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 sternohyoid myocutaneous RDF and HA ring is a relatively simple method with positive long-term effect for LT reconstruction.展开更多

Numerous cases are being published for patients with coronavirus disease 2019 (COVID-19) who end up with severe LTS after prolonged intubation or tracheostomy. Here, we presented two cases of LTS due to prolonged intubation after severe COVID-19 pneumonia. The characteristic of these two cases is that both of them needed second time intubation and were readmitted because of severe dyspnoea and all the workup for post-COVID-19 complications were investigated except the LTS which was later diagnosed after one month of suffering of these patients.展开更多

Laryngotracheal flap was used in hypopharyngaesophageal reconstruction for 26 elderly patients with advanced pyriform sinus cancer Pharyngocutaneous fistula developed in 5 patients and healed spontaneously without further surgery. Full diet was resumed in all the patients. The surgical technique and its advantages and disadvantages are discussed. The laryngotracheal flap in the reconstruction of hypopharyngoesophageal defect for elderly patients is a procedure of choice.展开更多

Methods: The heads and necks from 5 pre-pubescent sheep were harvested after humane anesthesia. After 2—5 days to allow for rigor mortis to resolve, a specimen was supported with sandbags on an operating table. Operative procedures including tracheotomy, medialization laryngoplasty, anterior cartilage grafting, tracheal resection with primary anastomosis, and laryngectomy with closure of the pharynx were attempted. Results: The ovine head and neck provided an accurate model for simulation of all attempted procedures. Ovine tissue resembled that of humans in mechanical properties and handling. Postsurgical endoscopy confirmed graft alignment. Conclusions: The sheep head and neck provides an inexpensive, realistic, and safe model for surgical training for a variety of open laryngotracheal procedures. This is particularly relevant given the recent emphasis on surgical simulation and the relative rarity of some of these pro-cedures in residency training.展开更多
