Surgery of Metastases in the Sensorimotor Cortex Performance and Clinical Results

Abstract

Tumor resection in the rolandic region, also known as sensorimotor cortex, is a challenge. This study aims at reviewing a series of patients undergoing resection of metastases in the sensorimotor cortex using a multimodal concept including neuronavigation, sonography, and intraoperative electrophysiological monitoring. Eleven patients suffering from metastases located in precentral (8) and postcentral gyrus (3) were analyzed concerning their functional motor outcome. Improvement of motor function could be seen in 5 patients 1 week after surgery, 5 patients remained unchanged, and only 1 deteriorated. Median survival time averaged 15 months. A multimodal approach, including preoperative and intraoperative neuronavigation, intraoperative sonography, and intraoperative electrophysiological monitoring can lead on to excellent functional outcome in surgery of metastases in the sensorimotor cortex.
