Evaluation of Neuronavigation in Glioma Surgery

Abstract

Background: Glioma is one of the most common intracranial tumors, the treatment for which is surgical resection. Cerebral gliomas in eloquent brain areas are closely associated with important structures. The deep location of such gliomas renders complete resection difficult overlaying structures can be injured, causing hemiplegia, aphasia, coma, and other severe complications. The degree of resection directly influences the prognosis of patients. The application of neuronavigation enables the accurate localization of lesions during surgery, significantly improving microneurosurgery. The accuracy of navigation, however, has typically been compromised by several factors, including operation error, shifting of registration system, and intraoperative brain tissue deformation (brain shift). Aim of Study: The aim of the study is to evaluate and demonstrate the efficacy of neuronavigation in the management of brain gliomas. Patients and Methods: This is a prospective randomized clinical trial study included 35 patients with brain glioma were operated for excision or biopsy taken. Results: Localization of burr hole and craniotomy flap was excellent in 33 patients (94.2%) and fault in 2 cases (5.7%), 29 patients (82.8%) had near total excision of the lesions, and 6 patients (17.1%) had burr hole biopsy, intra operative course was smooth in 33 patients (94.2%) with no intra operative complications, 2 cases (5.7%) developed intra operative bleeding that was due to liver problems. Reading the post operative imaging shows that 27 patients (77.1%) had mild to moderate post operative edema around the site of the lesion, the other eight cases were free of hemorrhage, infarction or edema. Conclusion: We found that neuronavigation is very helpful in our cases in localization of the lesions, decreasing time of surgery, reducing morbidity and mortality and decreasing hospital stay. There are concerns about navigation systems including time consuming, calculation and registration, restriction of space and view inside the operating field, and so on, we didn't find these issues as obstacles in our work, but we found that there are many advantages that can be helpful in the process of operation.

Navigating Brain Lesions Via Craniometric Points of Human Skull. Effectiveness in Targeted Craniotomy

“…They included 33 patients in their study, and in 33 patients (94.2%) the craniotomy flap was exactly on lesion and in 2 cases (5.7%), the trajectory was fault. 13 Du et al, conducted a study on neuronavigation for brain glioma. 75 patients were operated under neuronavigation, and in 62 patients (82.7%) they accurately removed tumor and in 13 patients (17.3) tumor was sub totally resected.…”

MFF‐Net: Multiscale feature fusion semantic segmentation network for intracranial surgical instruments

“…Radiation therapy and chemotherapy can help control the growth and spread of tumours, but they can also be physically damaging 2 . The point is that surgical resection requires a craniotomy, and since the location and size of gliomas vary, in different cases, symptoms such as convulsions, numbness, and loss of balance may occur 3,4 . The detection and segmentation technology of surgical instruments can help doctors quickly locate and recognise the shape and posture of intracranial surgical instruments during craniotomy and can also effectively separate surgical instruments from the surgical scene to avoid accidental injury of surgical instruments to surrounding tissues and organs, thereby improving surgical safety and efficiency.…”

Augmented reality surgical navigation system based on the spatial drift compensation method for glioma resection surgery

“…Ammar et al 3 presented a surgical navigation system for glioma resection. In that research, an optical tracker was used to track surgical tools in real time, which could minimize the scalp incision preoperatively.…”
