| pubmed-article:21227612 | pubmed:abstractText | Fibrous dysplasia, ossifying fibroma and osteomas are collectively known as fibro-osseous lesions. Occurrence in the sinonasal region is rare, and its management can be technically challenging. We report a case of an 8-year-old female with cemento-ossifying fibroma of the ethmoid sinus who underwent a two-staged, endoscopically assisted, transfacial resection of the lesion and a 31-year-old male with fibrous dysplasia of the ethmoid sinus who underwent endoscopic removal of the tumor. Both cases utilized intraoperative computed tomography (CT)-updated image-guided systems (IGS) to improve surgical precision. In the second patient, further resection was undertaken after CT-update in the same surgery. The postoperative courses were uneventful, and at 1-year follow-up no tumor recurrence was observed in either patient. Our experience suggested that the use of intraoperative CT-updated IGS in endoscopic or endoscopically assisted surgeries for sinonasal fibro-osseous lesions will lead to more optimal tumor control, which can translate into greater patient safety. | lld:pubmed |
