ABSTRACT
Background: The goal of management of laryngotracheal stenosis is reconstruction of cartilagenous framework with mucosal lining after removal of stenotic area and maintenance of effective airway. One of the successful procedures used to correct this condition is an autogenous cartilage graft to the stenotic area. The fate of the cartilage graft is not known, despite the good results of the procedure. Objectives: Among laryngotracheoplasty with various cartilages, we had used conchal or costal cartilage as graft material. We compared the results between conchal or costal cartilage as graft material in the management of laryngeal stenosis. Materials and methods: Twelve patients had a laryngeal stenosis. All patients were performed with laryngotracheoplasty using conchal or costal cartilage. Results: The following results were obtained. 1) After laryngotracheoplasties, the cases in need of granulation removal were 2 cases in conchal cartilage and 6 cases in costal cartilge. 2) Graft removal was done in a case of conchal cartilage graft because of infection and necrosis. 3) Successful decannulations were done in 10 cases, 5 in conchal cartilage, 5 in costal cartilage. Conclusion: Conchal cartilage was superior to costal cartilage as graft material in management of laryngeal stenosis.
