ABSTRACT
Rehabilitation of gunshot injuries that require combined reconstruction of bone and soft tissue poses a considerable challenge. We describe three cases of rehabilitation for mandibular defects and deformities caused by gunshot injuries. After debridement, three kinds of internal distractors were used. The bony transport discs were distracted about 10-22mm, and the new bone formed well in the distracted gaps. There was no evidence of infection during the consolidation period or follow up. Aesthetic appearance was also pleasing after treatment. Internal distraction osteogenesis after debridement might be a practical way of synchronously reconstructing bony and soft tissue after mandibular gunshot injuries.

Objective: To analyze the clinical applications of high frequency jet ventilation(HFJV) in cryotherapy of the trachea and bronchial neoplasms by the rigid bronchoscope. Methods: The clinical data of 35 patients who were treated with tracheal neoplasms cryotherapy by the rigid bronchoscopy under HFJV were collected in China-Japan Friendship Hospital from August 2008 to February 2015.Under general anesthesia, HFJV was used in all patients. The mean arterial pressure (MAP), heart rates (HR), pulse oxygen saturation (SpO(2)), results of arterial blood gas analysis and the incidence of complications during the procedure were recorded. Results: In the 35 patients, one case had multiple operations experience, he had an airway spasm after HFJV 40 min during his second operation, and severe hypoxemia after HFJV 5 min during his third operation, endotracheal intubation was performed immediately. The patient has a serious accumulation of carbon dioxide (CO(2)) whose partial pressure of carbon dioxide in the artery (PaCO(2)) was up to 71 mmHg(1 mmHg=0.133 kPa). Other patients had stable hemodynamics and no severe CO(2) accumulation. Conclusion: High frequency jet ventilation can provide satisfactory ventilation effect in cryotherapy of the trachea and bronchial end-stage neoplasms by the rigid bronchoscope.
