Abstract:

Objective: To investigate the microsurgery resection of sphenoid ridge meningiomas with pterion approach and study the protection of peripheral nerve and vascular. Methods: The conventional or expand pterion approach microsurgical excision was applied in the treatment of sphenoid ridge meningiomas, and the therapeutic effects were evaluated. Results: Tumor resection degree was evaluated by Simpson classification method. In 14 patients, 5 cases were I stage resection, 5 cases were II stage resection and 4 cases were IV stage resection. All patients were followed -up every 6 months, tumor recurrence was not found by imaging examination. Conclusion: Accurate and comprehensive preoperative evaluation, valid operation method and active postoperative therapy are the keys to improve the full excision rate, nerve symptoms restore as well as the postoperative complications in sphenoid ridge meningiomas treatment.
