We describe the case of a foreign body lodged into ethmoidal labyrinth and sphenoidal sinus with fracture of the clivus and consequent rhinoliquorrhea removed by an endoscopic technique. We performed a skull base plasty to close the rhino-liquoral fistula with resolution of the rhinoliquorrhea. There were no postoperative complications and there was a good therapeutic result at long-term follow-up.
