    Abstract:
    OBJECTIVE: To introduce a better surgical approach for the resection of malignant tumors in the anterior skull base and in the fronto-orbito-ethmoidal region. METHODS: A "U" form incision on the bilateral superciliary arch was made and connected with the unhealthy nasal side incision. Then the frontal musculocutaneous flap was over-turned upward. The nasal pyramid was over-turned to the healthy side. The malignant tumors in the anterior skull base and the fronto-orbito-ethmoidal region were fully exposed and resected. RESULTS: From december 1986 to december 1996, 50 patients received tumour resection through this approach. Postoperatively, the one-year survival rate was 86.0% (43/50), the three-year survival rate was 62.0% (31/50), and the five-year survival rate was 44.0% (22/50). CONCLUSION: The frontonasal flap overturn approach provided good exposure of surgical field, avoided the coronal incision, and the reaction of brain was mild. We believe this surgical approach is superior to traditional combined craniofacial approach.
