Sphenoid Sinus Foreign Body After Le Fort I Osteotomy.

ABSTRACT

This report describes a rare case of a foreign body in the sphenoid sinus from the tip of an osteotome, which was lodged during the Le Fort I osteotomy. After surgery, a 2-mm-diameter round-shaped foreign body was seen as an opaque image in the right sphenoid sinus on computed tomography. The tip of the broken osteotome (Bauer) was confirmed after the intraoperative instruments were investigated. The foreign body was removed using an interventional endoscope and navigation computed tomography, and a good prognosis was obtained.
