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.

Comparative StudyEnhancing outcomes in deep brain stimulation: a comparative study of direct targeting using 7T versus 3T MRI.
The aim of this study was to compare outcomes of direct targeting in deep brain stimulation (DBS) for essential tremor using 7T MRI versus 3T MRI. The authors hypothesized that 7T MRI direct targeting would be noninferior to 3T MRI in early tremor outcomes. ⋯ Despite concerns for increased artifacts and distortions at 7T, the authors show that these effects can be mitigated with an appropriate workflow, leading to improved surgical outcomes with direct targeting using 7T MRI. Their results suggest similar accuracy but greater precision in targeting with 7T MRI compared with 3T MRI, resulting in lower stimulation currents and improved tremor reduction. Future studies are needed to assess outcomes related to 7T MRI in targeting other subcortical structures.

Impact of collagen matrix on reconstructive material selection and postoperative complications in endoscopic endonasal skull base surgery.
The aim of this study was to investigate the impact of collagen matrix on reconstructive material selection and postoperative complications in endoscopic endonasal skull base surgery. ⋯ Collagen matrix implementation significantly decreased autologous graft harvesting without increasing postoperative CSF leakage, contributing to less invasive surgery.

Review Historical ArticleThe AANS/CNS Section on Tumors: a summary of 40 years of advocacy to advance the care of patients with brain and spine tumors.
The AANS/CNS Section on Tumors was founded 40 years ago in 1984 to assist in the education of neurosurgeons interested in neuro-oncology, and serves as a resource for other national organizations regarding the clinical treatment of nervous system tumors. The Section on Tumors was the first national physicians' professional organization dedicated to the study and treatment of patients with brain and spine tumors. Over the past 40 years, the Section on Tumors has built solid foundations, including establishing the tumor section satellite meetings, founding the Journal of Neuro-Oncology (the first medical journal dedicated to brain and spine surgical oncology), advancing surgical neuro-oncology education and research, promoting neurosurgical involvement in neuro-oncology clinical trials, and advocating for patients with brain and spine tumors. This review provides a synopsis of the Section on Tumors' history, its challenges, and its opportunities, drawing on the section's archives and input from the 17 section chairs who led it during its first 40 years.

Randomized Controlled TrialEffect of patient-controlled analgesia on development of postoperative nausea and vomiting in patients undergoing microvascular decompression: a prospective randomized controlled trial.
Postoperative nausea and vomiting (PONV) occurs frequently after microvascular decompression (MVD). Fentanyl, an opioid, is strongly related to the development of PONV, and ketorolac, a nonsteroidal anti-inflammatory drug, has been approved for postoperative pain management. However, how ketorolac-based patient-controlled analgesia (PCA) causes PONV or how its efficacy differs from that of fentanyl-based PCA after MVD is unclear. In this study, the authors compared ketorolac-based with fentanyl-based PCA in terms of the incidence and severity of PONV and analgesia after MVD. ⋯ In patients with MVD, ketorolac-based PCA resulted in a decrease in PONV incidence and severity compared with fentanyl-based PCA, with analgesic effects similar to those of fentanyl-based PCA. This study provides clinical evidence that ketorolac-based PCA may be a valid alternative to fentanyl-based PCA in postoperative care.
