    Abstract:
    OBJECTIVE: To explore the operative approach for nasosinus tumors involving the base of the anterior cranial fossa. METHOD: Seven cases with defects, diameter less than 2 cm, on the skull base without damage of the duramater were not repaired. Other 7 cases with defects, diameter more than 2.5 cm, on both the skull base and duramater were covered with frontalis muscle flap or temporalis fascia flap. RESULT: Following up 1-8 year. 6 of the 11 malignant tumors survived after 3 years and 2 cases did after 4 years; 3 cases of benignant tumors are still alive, neither meningoephalocele nor cerebrospinal fluid fistula and extracranial or intracranial infection occurred. CONCLUSION: This operative mode is closer to the tumor and easy to repair duramater and stop bleeding, and has fine exposure of every nasal sinus, minimal retraction of the frontal lobe. If diameter of defect is more than 2 cm on the skull base, the reconstruction is necessary.
