Strategy of awake surgical resection for glioma based on intraoperative functional mapping and monitoring: A case report

Abstract

We reported a case of awake surgery for the left frontal low-grade glioma and reviewed the literature on the strategy of awake surgical resection for glioma. The eloquent cerebral areas that are involved in motor, language, memory, and visuospatial functions, which have to be preserved during surgery, is identified through intraoperative use of brain mapping techniques. This technique of combining intraoperative ultrasound and neuronavigation enabled extension of the surgical indications and improved the extent of resection, while minimizing postoperative morbidity and safeguarding the patient's quality of life. This work was approved by the Institutional Review Board of Tangdu Hospital, Fourth Military Medical University, China.
