Objective:
To report 13 cases of ethmoid osteoma removed through an endoscopic approach and discuss the operative technique and clinical value.
Method:
Thirteen cases with ethmoid osteoma were retrospectively reviewed in the study. All procedures were performed with CT image guidance-according to the site of attachment. The anterior ethmoid cell was resected, and the whitish osteoma found. A double blunt elevator was used to separate the osteoma from ethmoid cell, and to push the osteoma medially toward the nasal septum, and (or) inferiorly toward the middle meatus. This method was performed in 7 patients (8 sides), whose CT scan showed the osteoma bases were not attached to lamina papyracea, and (or) anterior skull base. The others were drilled out with a intranasal powered drill for its attached to lamina papyracea in 4 patients and to anterior skull base in 2 patients.
Result:
Thirteen cases of ethmoid osteoma were removed completely through an endoscopic approach and there were no intraorbital or intracranial complication. Endoscopy showed normal epithelization at around 6 to 8 weeks after surgery.
Conclusion:
Preoperative CT scans, including coronal and axial images, is very helpful to determine the sites of the osteoma attachment and plan the operation. Endoscopic removal of ethmoid osteoma is not only an ideal, less invasive surgical approach, but also no cosmetic alteration.
