Abstract: Objective: To investigate the diagnosis and treatment of traumatic tracheal and bronchial rupture.Methods: The clinical data of 11 patients suffering from traumatic rupture of tracheal and bronchial were retrospectively analyzed.Among the 8 cases of bronchial rupture,6 were diagnosed by fibrobronchoscopy.Seven cases received end-to-end anastomosis and 1 was performed lobectomy.Of the 3 cases of tracheal rupture,2 cases whose crack's length was less than a third of the circumference of trachea were diagnosed by fibrobronchoscopy and received conservative treatment,and the rest one was performed end-to-end anastomosis.Results: All the 11 cases were cured.Conclusions: The bronchoscopy is the most important procedure for final diagnosis;and bronchoplasty is the capital modus operandi.Conservative treatment can be applied to the patients whose crack's length is less than a third of the circumference of trachea.
