Genden INTRODUCTION The history of tracheal reconstruction dates back more than 200 years. While many initially viewed the trachea as merely an airway conduit that could be replaced by an alloplastic tube investigators and surgeons have gained a greater respect for the complex biology of the airway. The tracheal airway plays a critical role in mucociliary transport airway hygiene and antigen processing. Ideally reconstructive techniques should strive to maintain these important functions. Tracheal airway defects can be classified into three categories Defects less than 4 cm defects between 4 and 6 cm and defects greater than 6 cm in length. Defects less than 4 cm are usually amenable to primary end-to-end anastomosis. Defects between 4 and 6 cm may require a multistaged reconstruction and defects greater than 6 cm continue to represent a reconstructive dilemma although a variety of techniques have been used to manage the latter group including allograft reconstruction alloplastic reconstitution and tracheal transplantation none has proven effective. HISTORY A careful preoperative history and physical examination are essential. I feel that a detailed history is important in trying to understand the nature of the tracheal problem particularly a history of prior surgery infection and compromised wound healing. The underlying cause of the tracheal problem is important because it will help to determine the best approach to the reconstruction and often estimate the risk of restenosis. Tracheal defects may be the result of trauma tumor resection congenital stenosis inhalational injury or acquired idiopathic disease. While defects from trauma and tumor resection are often focal in nature congenital and inhalational tracheal disease may result in more diffuse injury and therefore more extensive defects. In contrast idiopathic disease often involves the cricoid cartilage and therefore .
