The past decade has seen a significant shift in the number of centers performing intracranial electroencephalography from subdural grids and strips to stereoelectroencephalography (SEEG). Unlike grid and strip insertion or other stereotactic procedures in which the cortical surface is visualized, SEEG involves insertion of an electrode through a bolt anchored into the skull. Due to the multidisciplinary nature of SEEG trajectory planning, it often is time-consuming and iterative. Computer-assisted planning improves time taken and efficacy of SEEG trajectory planning. This article provides an overview of the considerations, controversies, and practicalities of implementing an automated computer-assisted planning solution for SEEG planning.

Objectives: Computer-assisted planning (CAP) allows faster SEEG planning and improves grey matter sampling, orthogonal drilling angles to the skull, reduces risk scores and minimises intracerebral electrode length. Incorporating prior SEEG trajectories enhances CAP planning, refining output with centre-specific practices. This study significantly expands on the previous work, compares priors libraries between two centres, and describes differences between SEEG in adults and children in these centres.

Background: Stereoelectroencephalography (SEEG) is a common diagnostic surgical procedure for patients with medically refractory epilepsy. We aimed to describe our initial experience with the recently released NeuroOne Evo SEEG electrode product (Zimmer Biomet, Warsaw, IN) and review technical specifications for other currently approved depth SEEG electrodes.
Methods: We performed a record review on the first five patients implanted with NeuroOne Evo SEEG electrode product using the robotic stereotactic assistance robot platform and described our surgical technique in detail.

Background: Stereoelectroencephalography (SEEG), as a minimally invasive method that can stably collect intracranial electroencephalographic information over long periods, has increasingly been applied in the diagnosis and treatment of intractable epilepsy in recent years. Over the past 20 years, with the advancement of materials science and computer science, the application scenarios of SEEG have greatly expanded. Bibliometrics, as a method of scientifically analyzing published literature, can summarize the evolutionary process in the SEEG field and offer insights into its future development prospects.

Background: We assessed the accuracy and performed a directional analysis of robot-assisted implantation of stereoelectroencephalography (SEEG) depth electrodes in children using the frameless neurolocate 3D registration module.
Methods: Thirteen children with epilepsy undergoing stereotactic robot-assisted insertion of SEEG electrodes were included. Six children were operated on with standard frame-based registration while 7 with the use of the frameless neurolocate registration module.

Article Synopsis
- - A 20-year-old man with drug-resistant epilepsy developed multiple intracerebral hemorrhages after receiving stereo-EEG electrodes and experiencing a lumbar spinal tap, with a history of heavy use of nicotine pouches.
- - Genetic testing revealed a mutation in the COL4A2 gene, which is linked to collagen production and has previously been associated with hemorrhage risks, raising concerns about its role in the patient's complication.
- - The study suggests that the combination of the COL4A2 mutation and high nicotine use could significantly increase the likelihood of bleeding during neurosurgical procedures, calling for more research into this connection.
