Rupture of a bronchus is an unusual result of blunt trauma to the chest. We experienced a case of bronchial rupture caused by blunt chest trauma without external wound or rib fracture. This case was a 13 years old male who was elementary school student. He was compressed on anterior chest by basket ball goal post being failed down on the afternoon of admission day. After this accident, he was suffered from progressive dyspnea and chest pain. The bronchial rupture was confirmed by bronchogram, The operation was performed through standard posterolateral thoracotomy incision along the 5th rib course. The right upper lobe bronchus and intermediate bronchus was completely transected. The right upper lobectomy was done. The ruptured intermediate bronchus was connected direct simply. Post-operative course was uneventful. Thus we report this case of traumatic bronchial rupture with review of literature.
