Surgery of gliomas in motor areas by localizing the central sulcus under awaking anaesthesia

Objective To study the protective effects of intraoperative waken-up and central sulcus location on motor function for patients with gliomas locating in motor areas.Methods 56 patients with gliomas in motor areas were intubated with laryngeal mask,rapidly underwent craniotomy without scalp clips,waken-up,localized the central sulcus by somatosensory evoked potential.On the condition of protecting the brain function,the greatest degree of tumor resection was performed and then the close-skull under awake state or general anesthesia was finished.Results All the patients underwent operation successfully.Except for the emergence of new nervous dysfunction in four patients,most patients' neurological functions were not deteriorated or even had improved.Besides,there was no complication and postoperative painful memories for the patients.Conclusions Resection of gliomas in motor areas with intraoperative waken-up and localization of central sulcus could ensure the largest degree of tumor resection on the premise of protection of the brain function.As a result,it could improve the prognosis of the patients.
