The aim of this study was to review the results of surgical treatment of long segment post intubation tracheal stenosis and the role of bilateral hyoid bone cutting in supra- hyoid release technique.
Methods: Between 2004 to 2008, 14 patients with proximal long segment tracheal stenosis with resection of more than 40% of trachea length were evaluated regarding surgical technique and post-operative results.
Results: The mean age of patients was 22.2±0.4 years. Etiology in all patients were head trauma and prolonged intubation and all patients had tracheostomy at the time of trearment. Average time between surgery and first admission was 4.5±0.5 months. Average length of stenosis and resected segment were 3.6±0.5 and 4.3±0.5cm respectively. Average increased length of trachea after bilateral hyoid bone cutting was 1.1±0.3cm. Postoperative complications occurred in one patient with wound infection, and 4 patients had stenosis recurrence which was treated in 3 patients using multiple dilation. Quality of life 2 years after surgery in 71% of patients were classified in good and excellent group. We didn't have any mortality.
Conclusion: Based on the fact that surgery is the best method of treatment in long and multi segment tracheal stenosis and tension in suture line is a serious problem, we recommend extended releasing technique including bilateral hyoid cutting in surgical treatment of these patients.
