Abstract: Objective: To investigate the causes of reoperative intracranial meningioma and the methods of reoperation.Methods: The clinical data of 18 patients undergoing reoperation in intracranial meningiomas were analyzed retrospectively.Results: In 18 patients,the complete resection was performed in 14 patients while the incomplete resection was performed in 4 patients.There were no perioperative and postoperative death.All patients were diagnosed with meningiomas by pathology.Conclusions: The grade of resection is the significant factor related to reoperation of meningioma.The residual tumor reoperation rate after incompletely resection is high and necessitates the reoperation.
