Evaluation of Functional Outcome Following Resection Of Supratentorial Lesions At Eloquent Brain Areas

Abstract

One of the biggest challenges in Neurosurgery is the good and accurate localization of different brain lesions specially those related to eloquent brain and cerebral cortex. Extent of resection is believed to be a key prognostic factor in Neurosurgery. Image guided surgery using a variety of tools or technologies to help achieve this goal had become a great need. With the Growing evidence in the literature, which suggests that a greater extent of resection positively affects overall survival, progression-free survival with better performance, It is believed that image guided surgery and mapping of eloquent brain areas offers advantages in terms of extent of resection and more effective in preventing damage to surrounding normal brain matter, minimizing the postoperative morbidity and ensuring a good quality of life. From 2016 to 2018, 19 patients underwent surgical excision of intra-axial lesions under TIVA and 6 patients underwent awake craniotomy aided with fMRI and IONM, to find out the surgical outcomes of these techniques in tumors in eloquent areas. The study took place in Nasser Institute Hospital, Egypt.
