Microsurgical management of meningiomas in central sulcus region

Abstract

Objective To explore the microsurgical outcome of meningiomas in central sulcus region.Methods A retrospective analysis of the clinical data and surgical results was performed in 42 meningiomas in central sulcus region.Results Of the 42 meningiomas in central sulcus region,total resection and sub-total resection were achieved in 36 and 6 cases,respectively.No death occurred postoperatively.Temporary motor or sensory disturbances occurred in 8 patients,all of which recovered within 2 weeks.All patients were followed up for about 3 to 60 months.10 cases out of 12 recovered from decreased muscle strength in limbs (or hemiparesis).One maintained his status and the other one suffered from deterioration.For the 10 patients with epilepsy preoperatively,systemic anti-epileptic therapy was administered and all of them were seizure free postoperatively.Of the 6 cases with tumor subtotally resected,2 cases suffered from tumor recurrence,one of which undertook second operation and the other one took radiotherapy.4 patients were lost during the follow up period.Conclusions Although meningiomas in central sulcus have close relationship with vessels of central sulcus,the superior sagittal snius and the central cortex,satisfactory clinical outcome can be achieved with perfect microsurgery skills.
