Post traumatic disruption of the laryngo-tracheal junction.
Of 43 tracheo-bronchial ruptures, 19 patients presented with disruption of the laryngo-tracheal junction which would appear to be a very specific anatomical lesion. The disruptions were secondary to blunt cervical trauma in 11 cases and strangulation in 8 cases. The disruption was complete in 14 cases and incomplete in 5. The lesion is very complex and involved the retraction of the lower part of the trachea into the mediastinum (14 cases), fracture of the cricoid ring (9 cases), bilateral recurrent nerve tears (14 cases), unilateral (4 cases) and retraction of the laryngeal mucosa with exposure of the cricoid cartilage in all cases. According to the complexity of the lesion, the treatment was: laryngo-tracheal resection and end-to-end anastomosis with treatment of the vocal cord palsy in 13 patients; simple end-to-end anastomosis in 4 patients who had an unilateral vocal cord palsy; 2 patients with a partial disruption were treated medically with endoscopic stenting and laser photocoagulation. All had restoration of airway patency and recovery of voice. The results contrast with the failures and reoperations reported in the literature and underline the necessity of complete evaluation and treatment of these complex lesions.
