Craniofacial resection for malignant nasal and paranasal sinus tumors assisted with the endoscope

Endoscopes were useful for the craniofacial resection at osteotomy, providing illumination from below and at the several procedures in the deep part of the nasal cavity. If a lateral rhinotomy incision is made, the combined transfacial and transnasal approaches avoid the limited working angle associated with the transnasal approach alone. Although an endoscopic approach is useful for treating sinonasal tumors, we should recognize its advantages and limitations.
