OBJECTIVE: Fluoroscopy-guided radiofrequency rhizotomy for trigeminal neuralgia relies on biplanar fluoroscopic imaging and surface landmarks. However, anatomical variations and imaging limitations often necessitate multiple attempts, leading to patient discomfort and increased procedural risks. This study evaluated the procedural outcomes of radiofrequency rhizotomy using preplanned trajectories and intraoperative computed tomography with neuronavigation. DESIGN: Retrospective study. SETTING: S

OBJECTIVE: Robot-assisted stereoelectroencephalography (SEEG) allows precise electrode placement in a reduced operative time. Conventional stereotactic surgeries rely on the center-of-arc principle; however, earlier robotic systems did not adopt this methodology. A table-mounted stereotactic robot based on the center-of-arc principle and integrated with neuronavigation was recently developed. This system aims to enhance stability, usability, and working space in the operating room through a prec

Trigeminal neuralgia (TN) is a debilitating condition characterized by severe facial pain, often refractory to medical therapy. Gamma Knife radiosurgery (GKRS) has emerged as a valuable therapeutic option for patients with TN, offering effective pain relief while minimizing the risk of complications associated with traditional surgical approaches. This review provides a comprehensive overview of the role of GKRS in the treatment of TN, focusing on its efficacy, safety, and technical consideratio

Abstract BACKGROUND Gamma Knife Radiosurgery typically involves a neurosurgeon, radiation oncologist and physicist. Neurologists performing Gamma Knife provides a potential paradigm shift. METHODS The first 100 Gamma Knife procedures were completed on an Elekta Perfexion or ICON system between October 2015 and August 2018. Head frames were placed by the treating neurologist who also completed the contouring and targeting. The Radiation Oncologist defined the prescription dose and verified the pl

Objective Intrathecal baclofen (ITB) therapy is an established treatment for refractory spasticity; however, long-term real-world data integrating both clinical outcomes and device-related factors remain limited. This study aimed to evaluate long-term outcomes and device-related management issues associated with intrathecal drug delivery systems, with a primary focus on intrathecal baclofen therapy for refractory spasticity. Methods We retrospectively reviewed 137 patients who underwent intrathe

Pituitary adenoma (PA) is a benign tumor that arises from the anterior pituitary gland. PA is categorized into non-functioning and functional types, and each type requires specific treatment strategies. While transsphenoidal surgery (TSS) remains the first choice of PA management, its limitations necessitate adjunctive therapies such as stereotactic radiosurgery (SRS), particularly in cases of residual or recurrent tumors. In this review, we explore the role of SRS in PA, particularly emphasizin
