[Tracheobronchial perforations--a complication after mouth, maxillary and facial surgery].

After difficult endotracheal intubation in oral and maxillofacial surgery, esophageal or tracheal injuries can cause mediastinal, pericardial or cervicofacial soft tissue emphysema. If a patient has of thoracic pain after general anesthesia, mediastinal emphysema should be taken into consideration because of the possibility of subsequent life-threatening complications. Diagnosis can be established with computed tomography and fiber-endoscopy. We present the diagnostic and therapeutic management of two patients.
