Introduction: Diffuse gliomas are primary tumors of the central nervous system that remain a challenge for medicine, despite improvements in treatment techniques, due to their dynamic patterns of growth and behavior. One of the treatment alternatives currently studied is based on the percentage of resection and the eloquent area involved. The first is an important independent prognostic factor that defines patient survival. Objective: To show the casuistry of the asleep approach to surgery of tumors in the motor area. Method: Retrospective study in patients undergoing asleep surgical resection of high-grade gliomas, with intraoperative somatosensitive motor electrophysiological monitoring, of the partial, subtotal and total types, using craniotomy and microsurgery. Results analysis was based on the evaluation of postoperative Evolution by the Karnofsky Scale. Results: For the verified sample, it can be suggested that the asleep operative technique is safe to be employed in the motor areas. All patients who presented deficits died due to the aggressive nature of the disease. Conclusion: The asleep operative technique has been found to be safe for use in the motor areas, having extremely low intraoperative complications, and its prognostic evolution depends on the initial aggressiveness of the tumor.
