KQ 10.1 This chapter discusses the prevention and management of tracheal and bronchial wall injuries during endoscopic airway surgery for foreign body removal. Key strategies include using appropriately sized bronchoscopes, applying lidocaine gel, and carefully maneuvering instruments to avoid damage. Additionally, it explores the management of stenosis caused by such injuries. KQ 10.2 This chapter addresses the prevention and management of acute airway obstruction following endoscopic airway surgery. Key preventive strategies include minimizing tracheal irritation by avoiding direct contact with instruments and administering intravenous steroids to reduce postoperative airway edema. KQ 10.3 This chapter discusses about minimizing complications during partial cricotracheal resection. Emphasis is placed on thorough preconditioning and careful patient selection to improve surgical outcomes in patients with airway obstruction and stenosis. Key strategies include meticulous airway mobilization with precise dissection around the recurrent laryngeal nerve (RLN) and careful preservation of the vascular supply from the tracheoesophageal grooves. Thoughtful suture placement further enhances mucosal approximation. KQ 10.4 This chapter presents essential techniques for using costal cartilage grafts in laryngotracheal reconstruction to prevent airway collapse, leakage, and restenosis. The process includes careful airway exposure, precise incision, and strategic graft design to fit anterior and posterior defects.
