Background The application of imaging during surgery can improve patient outcomes by accurate and thorough removal of lesions while having minimal impact on healthy tissue. Aim of the Work to compare the use of neuronavigation to intraoperative ultrasound guidance in excision of intra-axial brain lesion. Patients and Methods This cohort study was conducted on 51 patients with intra-axial brain lesion is amenable to gross total resection. The primary outcome was extent of resection assessed using a non-volumetric technique. Other outcomes included the postoperative functional status and the rate of operative complications. Results There were 34 patients in the Neuronavigation group and 17 patients in the ultrasound group. The extent of resection was significantly better in the ultrasound group as the extent of tumor resection based on the GTR/NTR/STR method of assessment showed that the IOUS group had statistically significant higher chance of achieving GTR (29.4%) than the navigation group (8.8%). In the IOUS group near total and subtotal resection rates were 17% and 52% respectively. In neuronavigation group 11.8% and 79.4%. Conclusion application of ultrasound integrated in Neuronavigation system guidance in surgery excision of intra-axial brain lesions is a useful tool in achieving a higher extent of tumor resection (EOR).
