title: Surgical results of parasagittal and falx meningioma.
abstract: Sixteen operative cases of parasagittal and falx meningioma were analyzed retrospectively. Parasagittal meningioma totaled 12 cases and falx meningioma numbered 4 cases. Preoperative symptoms were paresis of a lower extremity in 7 cases and disturbed consciousness or mentality in 6 cases. Paresis and/or consciousness deteriorated just after the operation in 11 cases. The deterioration was identified in paresis (6 cases), consciousness (3 cases), paresis and consciousness (2 cases). Motor function further deteriorated postoperatively when the patients had shown preoperative paresis. The cause of postoperative deterioration of motor function and/or consciousness level was intracerebral hematoma in 1 case, and newly-developed brain edema in 1 case. There was no obvious explanation for the symptomatic exacerbation in the other 9 cases. At discharge, 5 cases showed deterioration of motor function in comparison to their preoperative condition, and 3 cases showed an improvement. Eleven cases showed no change of consciousness in comparison to the preoperative condition, and 5 cases showed improvement at discharge. Surgical result was good for consciousness or mentality, but was relatively poor for motor function. It was considered that surgery should be performed carefully in patients with preoperative paresis.
