|概要||OBJECTIVE Resection of gliomas in the precentral gyrus carries a risk of severe motor dysfunction. To prevent permanent, severe postoperative motor dysfunction, reliable intraoperative predictors of postoperative function are required.
Since 2005, the authors have removed gliomas in the precentral gyrus with combined functional mapping and estimation
of intraoperative voluntary movement (IVM) during awake craniotomy and transcortical motor evoked potentials (MEPs).
The purpose of the current study was to evaluate whether intraoperative findings of combined monitoring of IVM during
awake craniotomy and transcortical MEP monitoring were useful for predicting postoperative motor function of patients
with gliomas in the precentral gyrus.
METHODS The current study included 30 patients who underwent resection of precentral gyrus gliomas during awake
craniotomy from April 2000 to January 2018. All tumors were removed with monitoring of IVM during awake craniotomy
and transcortical MEPs. Postoperative motor function was classified as stable or declined, with the extent of decline categorized as mild, moderate, or severe. We defined moderate and severe deficits were those that hindered daily life.
