    Abstract:
    OBJECTIVE: To discuss the role of image navigation in resection of the ossifying fibroma of paranasal sinuses and anterior skull base with nasal endoscope. METHOD: Fourteen cases with ossifying fibroma involving paranasal sinuses and anterior skull base were underwent intranasal endoscopic surgery under the guidance of image navigation. Sequential nasal sinuses CT scans were obtained before and after operation. CT scans demonstrated that the nasal septum, orbital wall and anterior skull base were involved in every case. The anterior boundary of the frontal recess cells was involved in 10 cases. The lesions were adjacent to the orbital apex and optic canal in 5 cases. The sella turcica and clivus were invaded in 3 cases and the pterygopalatine fossa was invaded in 2 cases. RESULT: The tumors were thoroughly removed in all cases. The average operative time was 280 minutes and the average registration time of navigation was 9 minutes. Postoperation CT scans demonstrated that the tumors were totally resected. CONCLUSION: The image-guided endoscopic surgery of the ossifying fibroma of paranasal sinuses and anterior skull base provided accurate tumor resection, increased surgical effectiveness, decreased overall surgical complications.
