Achieving this requires preoperative imaging, intraoperative cranial nerve monitoring, and adequate dissection of the layers. High-resolution magnetic resonance imaging, including diffusion tensor imaging and contrast-enhanced fast imaging employing steady-state acquisition, allows preoperative visualization of the facial and cochlear nerve courses. Additionally, three-dimensional (3D) reconstructed images aid in simulating nerve trajectories relative to tumors within the surgical field. The facial and cochlear nerves were identified intraoperatively through direct observation or electrical stimulation. Preoperative 3D simulations facilitate the identification of nerves and reduce the risk of nerve injury. Tumor resection should begin from the safer petrous side, and sufficient debulking improves the visualization of the tumor-brainstem interface. Identifying the subperineural cleavage plane in the V-zone is crucial to establish an optimal dissection layer for maximum safe resection. However, continuous facial and cochlear monitoring is essential for detecting potential nerve damage. If necessary, the dissection plane should be adjusted, leaving a thin tumor layer to prevent nerve injury. This study provides practical insights into the optimization of imaging use in vestibular schwannoma surgery for functional preservation.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 2","pages":"288-299"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve safe and maximal resection, determining the resection area through neuronavigation and awake brain functional mapping is crucial. The three-dimensional (3D) virtual imaging model used for intraoperative navigation proves beneficial during surgery and in preoperative surgical simulation. These imaging models are primarily reconstructed by integrating 3D structural data depicting normal brain anatomy surrounding the lesion, 3D tractography visualizing the white matter neural network, and functional localization data obtained from functional magnetic resonance imaging (MRI). The success of awake surgery relies heavily on a comprehensive understanding of the functional network of the brain and preoperative surgical simulation, with 3D tractography playing a pivotal role in strategizing awake mapping of the cortex and white matter. By correlating intraoperative findings from awake mapping with navigation data, including tractography and functional MRI, further advancements in understanding brain functional anatomy and its clinical applications are anticipated in the future.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 2","pages":"253-262"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brain tumor surgery aims to safely remove as much of the tumor as possible while preserving brain function. However, invasive brain tumors, such as gliomas, are often difficult to distinguish from the normal brain, and removal of the entire tumor may inadvertently damage the normal brain tissue, resulting in the risk of serious postoperative complications. Additionally, brain tissue is subject to brain deformation, called brain shift, because of cerebrospinal fluid drainage and tumor removal. This reduces the accuracy of neuronavigation during preoperative planning, resulting in differences in the exact locations of the tumor and nerve fibers. Intraoperative magnetic resonance imaging (MRI) enabled to identify the exact tumor position and residual tumor in real-time perioperatively, compared to surgery that relies on the surgeon's experience and skill, enabling highly accurate surgery. Moreover, the fusion and comparison of preoperative images and latest intraoperative MRI images enable the accurate evaluation of tumor location and safe tumor removal. Intraoperative MRI imaging-assisted techniques that can capture residual tumor morphology and awake surgery that preserves brain function should be integrated to complement each other's roles.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 2","pages":"385-390"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its principal function is to recalibrate navigational datasets, compensating for brain shift and ensuring optimal surgical precision throughout the procedure. Additionally, iMRI facilitates the intraoperative assessment of surgical endpoints, such as confirming the extent of resection and verifying whether gross total resection has been achieved. Moreover, it plays a pivotal role in detecting occult intraoperative complications, including intraprocedural hemorrhage, which might not be evident through direct visual assessment alone. In glioma surgery, the integration of iMRI significantly improves resection quality and may lead to prolonged overall and progression-free survival. This has led to recommending iMRI in established U.S. clinical guidelines. Stringent adherence to magnetic field safety protocols is paramount when implementing iMRI systems. It is crucial to prohibit the presence of ferromagnetic surgical instruments and use of MR-compatible devices within the 5-gauss line to avoid potentially catastrophic projectile incidents or equipment malfunctions. Furthermore, establishing comprehensive institutional protocols and rigorous training programs for all personnel is mandatory to ensure compliance with safety standards and maintain procedural integrity.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 2","pages":"241-252"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
