[Clinical analysis and surgical discussion of juvenile ossifying fibroma in nasal root].

To analyze the clinical features of juvenile ossifying fibroma in nasal root and to compare different surgical methods. Seven cases of juvenile ossifying fibroma occurring in the nasal root were treated via surgery, 5 cases were resected under nasal endoscopy guided by Image Guidance System-based electromagnetic navigation, and 2 cases were resected by lateral nasal butterfly incision. Postoperative follow-up included endoscopy and CT scan of the sinuses. The pathological results of 7 patients were consistent with juvenile ossifying fibroma. Follow-up period ranged from 6 to 45 months, and there were no recurrence or surgical complications. Surgery is the only effective treatment. Endoscopic sinus surgery with image navigation and lateral nasal butterfly incision resection has been deemed available. The external nasal butterfly incision has less bleeding and shorter operation time, but with mild nasal face swelling after surgery, and nasal endoscopy is a surgical method with less damage.
