Repair of large airway defects with bioprosthetic materials %K %X Tracheal resection is currently performed both for benign and malignant diseases and its reconstruction is usually obtained by using primary re-anastomosis (1). Most reports suggest 4 to 6cm of trachea or approximately 8 tracheal rings or 50% of the whole tracheal length in adults or 30% in children can be removed, performing pulmonary hilar release, suprahyoid release, and cervical neck flexion to decrease anastomotic tension (2-4). Longer segments of the trachea cannot be safely removed and since the first reports of tracheal surgery by Hermes Grillo in 1965, it still remains an unsolved problem (5). %U http://jtd.amegroups.com/article/view/16402 %V 9 %N 10 %P 3674-3676 %@ 2077-6624
