Surgical treatment of gliomas involving the supplementary motor area in the superior frontal gyrus / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore surgical treatment of gliomas involving the supplementary motor area (SMA) in the superior frontal gyrus.</p><p><b>METHODS</b>Clinical data and follow-up outcome of 16 patients with low graded astrocytomas involving the supplementary motor area were analyzed.</p><p><b>RESULTS</b>SMA syndrome was developed in 6 patients in whom the posterior tumor resection line was at a distance of more than 1 cm from the precentral sulcus and resolved after 12 months. Hemiplegia occurred however in 8 patients in whom the resection line was less than 1 cm to precentral sulcus and only resolved in 3 patients during follow period 12 months.</p><p><b>CONCLUSIONS</b>When the resection is performed at a distance of less than 1 cm from the precentral sulcus, surgery for gliomas of involving the supplementary motor area in the superior frontal gyrus may be result in permanent morbidity.</p>
