Abstract

Laryngotracheal separation (LTS) is the most immediately life-threatening airway injury. LTS is so rare that very few otolaryngologists have experience with it. LTS is one of the diagnostic and therapeutic challenges in airway diseases and its management remains to be established. We experienced a patient with complete LTS after attempted hanging. A high index of suspicion, adequate imaging, prompt airway establishment and early surgical repair are the most vital factors in managing a patient with LTS.

Figure

  • Fig. 1 Preoperative computed tomography (CT) findings. Axial (A), coronal (B), and sagittal (C) image of multi-detector CT reveal extensive subcutaneous emphysema and a complete laryngotracheal separation (arrow) without fractures of the thyroid and cricoid cartilage. Laryngotracheal separation is observed most clearly in the sagittal reconstruction images.

  • Fig. 2 Intraoperative finding. Complete transection between the cricoid cartilage and the first tracheal ring and stretching of the left recurrent laryngeal nerve (arrow) are observed. Thyroid gland is retracted laterally after dividing the isthmus.

  • Fig. 3 Postoperative computed tomography (CT) findings. Axial (A), coronal (B), and sagittal (C) image of multi-detector CT taken at postoperative 10 days show complete resolution of subcutaneous emphysema and appropriate reconstruction of laryngotrachea.

  • Fig. 4 Proposed algorithm for management of LTS. LTS, laryngotracheal separation; UADT, upper aerodigestive tract; MDCT, multi-detector CT; ER, emergency room; OR, operation room.
