摘要:A-50-year-old male patient presented with complaint of tenderness on the left malar area after traffic accident. Our first impression on him was zygomatic fracture, we did radiologic work-up and physical examination on him. But, on the computed tomography scan, there was no fracture or discontinuity on his facial bone. The computed tomography scan was revealed a 4-cm long foreign body in left maxillary sinus with a large amount of fluid collection. After thorough history taking from him, we reveal the patient had a history of trauma 30 years back on the left zygomatic area with a chopstick. The foreign body was removed via transoral approach with the endoscopic assist. There was no complication after operation.
