title: An unusual foreign body: a ball bearing in the posterior ethmoid sinus.
abstract: Globe perforation was detected in an 18-year-old male patient having total vision loss in the left eye following a car accident. The middle meatus could not be evaluated by sinonasal endoscopy because of edema. Computed tomography showed a foreign body in the left posterior ethmoid sinus, with a trajectory coursing from the globe to the lamina papyracea, and the posterior ethmoid sinus. Endoscopic sinus surgery was performed including a left uncinectomy, anterior and posterior ethmoidectomies, and the foreign body was removed from the posterior ethmoid sinus using ethmoid forceps. It turned out to be a ball bearing. After three months of follow-up, the patient had no evidence for rhinologic sequelae.
