A 24-year-old man was shot accidentally by an air gun. A bullet went through the left eye socket, and a large fragment was lodged in the left sphenoidal sinus. Computed tomography and arterial angiography revealed two fragments. Two months after the imaging studies, a large fragment in the sphenoidal sinus was removed by endoscopic paranasal surgery using an image intensifer. With respect to foreign bodies lodged in the paranasal sinuses, it has been reported that the most frequent site was in the maxillary sinus, followed by the ethmoidal sinus and the sphenoidal sinus. Metallic foreign bodies are generally safer than organic plant foreign bodies which can easily induced an inflammatory process. It is prudent that a foreign body in the paranasal sinus should be removed as early as possible, even if the foreign body is metallic.
