OBJECTIVES: We assess the utility and limitations of an endoscopic technique in the treatment of osteomas that are considered difficult to manage endoscopically, ie, those located superiorly or laterally in the frontal sinus, extending beyond a virtual plane through the lamina papyracea, and we describe the principles of a surgical technique that facilitates removal of such tumors. METHODS: We performed a retrospective study on 8 patients with symptomatic frontal sinus osteomas, including tumors extending past the commonly recognized limits of endoscopic resection because of their size or site of attachment. RESULTS: All tumors were removed by a purely transnasal endoscopic approach. No major complications were observed during or after the operation. All patients experienced improvement or total regression of their symptoms. CONCLUSIONS: With appropriate instruments and specific endoscopic techniques, it is possible to resect osteomas that not long ago were deemed inaccessible to endoscopic surgeons. The commonly recognized limits of endoscopic treatment of such tumors may be exceeded in some cases; however, favorable anatomic conditions are decisive for a successful operation.
