Objective: To analyze and summarize the methods and main points of microsurgical treatment of parasagittal meningioma. Methods: Twenty-two cases of parasagittal meningioma were confirmed by pathology. There were 10 males and 12 females, aged 21-68 years, with a mean age of 42 years. The tumors were located in the left side of the sagittal sinus in 9 cases, right in 11 cases, involving both sides of the two cases, located in the anterior sagittal sinus 1/3 in 4 cases, 1/3 in 15 cases, after 1/3 of 3 example. Tumor size 3 ~ 6.8cm. Results: Microsurgical treatment was performed according to the Simpson excision criteria: grade Ⅰ resection in 6 cases, grade Ⅱ resection in 12 cases, grade Ⅲ resection in 4 cases, without operative death and new neurological dysfunction. Followed up for 6 months to 5 years no tumor recurrence. CONCLUSIONS: Microsurgical techniques can preserve neurological function well with small damage, and tumor resection can reach Simpson Ⅰ ~ Ⅱ level.
