Initial United States experience with Medtronic Stealth Autoguide cranial robotic guidance platform.
Stereotactic techniques play an important role in neurosurgery. The development of a miniaturized cranial robot with an efficient workflow and accurate surgical execution is an important step in a broader application of these techniques. Herein, the authors describe their experience with the Medtronic Stealth Autoguide miniaturized cranial robot. ⋯ The Medtronic Stealth Autoguide robot system is versatile across biopsy, SEEG, and laser ablation indications. Setup and surgical execution are efficient with a high degree of accuracy and consistency.

Multicenter StudyA nomogram to predict long-term facial nerve function after vestibular schwannoma resection: a contemporary multi-institutional study.
The objective of this study was to develop a nomogram to predict long-term facial nerve (FN) function after vestibular schwannoma (VS) resection. ⋯ Better immediate postoperative HB grade, intraoperative FN EMG response ≥ 100 µV, and tumor size ≤ 25 mm strongly predicted good long-term FN function after VS resection. A point-of-care nomogram based on these variables could serve as a useful tool for postoperative counseling and prognosis of long-term FN recovery.

Turning the operating room into a mixed-reality environment: a prospective clinical investigation for cerebral aneurysm clipping.
The overall aim of this study was to demonstrate the potential benefit of a novel mixed-reality-head-mounted display (MR-HMD) on the spatial orientation of surgeons. ⋯ The incorporation of mixed reality in neurosurgical operations marks a significant advancement in the field. The use of mixed reality in brain surgery enhances the spatial awareness of surgeons, enabling more instinctive and precise surgical interventions. This technological integration promises to refine the execution of complex procedures without compromising accuracy.

Brain tumor surgery guided by navigated transcranial magnetic stimulation mapping for arithmetic calculation.
The onco-functional balance represents the primary goal in neuro-oncology. The increasing use of navigated transcranial magnetic stimulation (nTMS) allows the noninvasive characterization of cortical functional anatomy, and its reliability for motor and language mapping has previously been validated. Calculation and arithmetic processing has not been studied with nTMS so far. In this study, the authors present their preliminary data concerning nTMS calculation. ⋯ Based on the authors' preliminary data, nTMS can be an advantageous tool to study cognitive functions, aimed at minimizing neurological impairment. The postoperative clinical outcome for patients who underwent operation with nTMS was very good. Considering these results, nTMS has proved to be a feasible method to map cognitive areas including those for calculation functions. Further analyses are needed to validate these data. Finally, other cognitive functions (e.g., visuospatial) may be explored with nTMS.

Sub-Saharan African experience of neurosurgical oncology care: challenges and barriers encountered at 7 cancer treatment centers.
Wide disparities in neurosurgical oncology care and treatment outcomes exist globally despite recent improvements in diagnostics and cancer therapy. To better understand the challenges to neurosurgical oncology care in low-resource settings, the authors collected data on national neurosurgical capacity and hospital diagnostic and treatment capacity across 7 national referral hospitals in 7 countries in sub-Saharan Africa (SSA). ⋯ There are significant challenges to timely and quality neurosurgical oncology care in SSA especially for children. System-level interventions are needed to strengthen neurosurgical oncology care capacity in SSA.
