Strategies for resection of lesions in the motor area: preliminary results in 42 surgical patients.
In recent years considerable technological advances have been made with the purpose of improving the surgical results in the treatment of eloquent lesions. The overall aim of this study is to evaluate the postoperative surgical outcome in 42 patients who underwent surgery to remove lesions around the motor cortex, in which preoperative planning by using neuroimaging exams, anatomical study, appropriate microsurgery technique and auxiliary methods such as cortical stimulation were performed. Twenty-two patients (52.3%) presented a normal motor function in the preoperative period. Of these, six developed transitory deficit. Twenty patients (47.6%) had a motor deficit preoperatively, nevertheless 90% of these improved postoperatively. Surgery in the motor area becomes safer and more effective with preoperative localization exams, anatomical knowledge and appropriate microsurgery technique. Cortical stimulation is important because it made possible to maximize the resection reducing the risk of a motor deficit. Stereotaxy method was useful in the location of subcortical lesions.
