However, no significant progress has been made in this regard over the past decade. In 2008, a high-definition exoscope (HDXO-SCOPE) system developed by Mamelak et al. achieved a focal length of approximately 200 mm with an accuracy comparable to that of an operating microscope. This camera, commercialized as VITOM® (Karl Storz) was smaller than an operating microscope but had a wider field of view. Furthermore, the VITOM® was later adapted to three-dimensional imaging, providing an experience similar to microsurgery. The ORBEYE® (Olympus), on the other hand, was developed as an alternative to the operating microscope and provided a three-dimensional field of view with a focal length of 220 to 550 mm. The most significant advantage of the exoscope is the increased freedom of surgical positioning. Conventional microscopes restrict the surgical approach and surgeons' physical position when conducting surgery, which can be problematic. On the other hand, the exoscope reduces burden on the arms and body and allows for more precise surgery. The exoscope is especially useful in surgeries of posterior cranial fossa, and surgeries on elderly patients. The use of an exoscope also allows greater flexibility when conducting surgery of midbrain lesions. In general, exoscopes are good alternatives to microscopes for brain tumor surgery; however, the current technology should be further improved. Exoscopes are expected to ultimately surpass surgical microscopes in the future leading to their adoption in an increasing number of surgeries.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 2","pages":"263-270"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743997","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}

In North America, the advent of commercially available surgical robotic systems has initiated a paradigm shift from SDE to SEEG implantation. Advances in robotic technology have enabled the precise and efficient placement of depth electrodes for SEEG. In Japan, robot-assisted stereotactic electrode placement has been covered by National Health Insurance since 2020, further promoting its adoption. SEEG relies exclusively on intracerebral depth electrodes, which are stereographically inserted through twist drill holes or burr holes, eliminating the need for craniotomy-a requirement for SDE implantation. The planning of electrode trajectories is critical and must be meticulously performed using three-dimensional gadolinium-enhanced magnetic resonance imaging datasets to avoid vascular structures. Unlike SDE, SEEG allows for accurate sampling of cortical areas at the surface of hemispheres and bottom of sulci and deep-seated structures, such as the insular cortex, cingulate gyrus, and medial temporal lobes. This section provides a comprehensive overview of the indications for SEEG, the method of electrode implantation using robotic systems, the advantages of SEEG over other monitoring techniques, and its associated risks.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 2","pages":"357-367"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744177","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}

Intraoperative MRI and CT provide real-time assessment of residual tumors and vascular structures, and the integration of AI allows high-resolution imaging even with low-field MRI systems. Neuroendoscopes and exoscopes equipped with 4K resolution or 3D technology have improved visual precision, while AI aids in tumor boundary identification and postoperative outcome prediction. The integration of robotic technology further enhances surgical accuracy.

The Ministry of Health, Labor, and Welfare is promoting regional medical care vision plans to restructure healthcare delivery across different administrative levels, addressing evolving medical demands and population changes. However, the implementation of these plans has been uneven, with many regions focusing primarily on reducing hospital beds rather than on effectively redistributing medical roles and functions. Time constraints have hindered meaningful discussions regarding comprehensive healthcare restructuring. The text illustrates these challenges through two case studies in the Fukuoka Prefecture: Fukuoka-Itoshima and Keichiku areas. These regions demonstrate contrasting demographic trajectories with significantly aging and declining working-age populations. Notably, the Fukuoka-Itoshima area anticipates a substantial increase in cerebrovascular disease hospitalizations, whereas Keichiku expects moderate changes. This analysis suggests that future neurosurgeons must be adaptable professionals capable of navigating clinical, management, and policy domains. By 2040, they should proactively develop strategies to address demographic changes and involve current medical trainees and students in strategic planning of the healthcare landscape.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 2","pages":"415-428"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744140","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}

BrainLab Elements (BrainLab Corp.) has several functions in image analysis, such as image fusion, auto-segmentation, software for stereotactic surgery, and lead localization. In preparation for deep brain stimulation (DBS) electrode implantation, many sequences of magnetic resonance (MR) and computed tomography (CT) images are imported into the elements and fused automatically. Subsequently, important deep structures, such as the subthalamic nucleus (STN) , thalamus, and globus pallidus, were automatically segmented. This segmentation provides information on the outline of those that are invisible based on normal MR equipment and helps set the tentative target. Postoperatively, the DBS electrode data were extracted from postoperative CT images and fused with preoperative MR images. Using Stimview XT software (Boston Scientific Corp.) installed in the stimulation programmer, we confirmed the anatomical relationship between the location of the electrodes and structures of the stimulation target and adjusted the stimulation conditions. In robot-assisted DBS electrode implantation, elements could be useful in setting the tentative target and frame-based stereotactic surgery. Navigation systems are useful in the field of stereotactic neurosurgery and can be further developed eventually.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 2","pages":"349-356"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744199","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}
