[Surgical treatment of gliomas involving the supplementary motor area in the superior frontal gyrus].
OBJECTIVE
To explore surgical treatment of gliomas involving the supplementary motor area (SMA) in the superior frontal gyrus.


METHODS
Clinical data and follow-up outcome of 16 patients with low graded astrocytomas involving the supplementary motor area were analyzed.


RESULTS
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.


CONCLUSIONS
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.
