title: Endoscopic endonasal removal of a sphenoidal sinus foreign body extending into the intracranial space.
abstract: Sphenoidal sinus foreign bodies are very rare entities that are often associated with a cranial and/or orbital trauma. In this paper, a case of a metallic foreign body that pierced the sphenoid sinus and penetrated into the intracranial space due to a work accident is presented. A 29-year-old male was referred to our clinic due to a right orbital penetrating trauma. Skull X-ray and computed tomography (CT) scans demonstrated a foreign body inside the sphenoidal sinus, extending to the left temporal fossa. The foreign body was removed using an endoscopic endonasal technique, and the skull base was reconstructed with a multilayer closure technique. There were no complications during or after the operation. Postoperative result was perfect after three months of follow up.
