Review Case Reports
Macrovascular Decompression for Hemifacial spasm using Sling Technique.
Hemifacial spasm (HFS) is a painless, involuntary twitching of the facial muscles that usually involves the orbicularis oculi muscle.1,2 It is commonly caused by the anterior inferior cerebellar artery or posterior inferior cerebellar artery.1,2 However, a dolichoectatic vertebrobasilar artery (VBA) can impinge the facial nerve.1 Macrovascular decompression with sling transposition is a common management paradigm.1-9 We present a case of a 56-year-old male who presented with left-sided HFS, pulsatile tinnitus, and hearing loss for the past 2 years. The patient underwent a retrosigmoid craniotomy and Gore-Tex sling transposition of a dolichoectatic VBA (Video 1). Complete improvement of symptoms was noted postoperatively with no associated complications. We review the preoperative workup, operative technique, relevant anatomy, and literature and provide technical pearls for this procedure.

Over the last century, collaboration between clinical neuropsychologists and neurosurgeons has advanced the state of the science in both disciplines. These advances have provided the field of neuropsychology with many opportunities for innovation in the care of patients prior to, during, and following neurosurgical intervention. ⋯ Improvements in remote platform, computer interface, "real-time" analytics, mobile devices, and immersive virtual reality have the capacity to increase the customization, precision, and accessibility of neuropsychological services. In doing so, such innovations have the potential to improve outcomes and ameliorate health care disparities.

The use of directional deep brain stimulation (dDBS) electrodes for the treatment of movement disorders such as Parkinson disease (PD) has become relatively widespread. However, the efficacy of dDBS relative to its omnidirectional deep brain stimulation (oDBS) counterpart is not well characterized. This systematic review aims to synthesize the literature comparing clinical and therapeutic outcomes of dDBS relative to oDBS in patients with PD. ⋯ The current evidence, although limited by bias, does suggest that dDBS in the treatment of PD yields improvements in motor symptoms and quality of life that are comparable to oDBS; TW and surrogate measures are consistently improved in patients with PD under a directional configuration relative to omnidirectional.

Thrombectomy is now the standard of care in the treatment of acute ischemic stroke caused by emergent large vessel occlusion. Therefore thrombectomy services have expanded from Comprehensive Stroke Centers to Thrombectomy-Capable Stroke Centers. Stroke interventions at these sites are performed in both biplane and monoplane angiography suites. It has been hypothesized that differences in these systems may affect time to successful reperfusion, with a potentially significant effect on neurologic outcomes. With an increase in TSCs, this study aims to evaluate the safety and efficacy of monoplane thrombectomy versus biplane thrombectomy. ⋯ Despite perceived advantages of biplane systems in reducing procedural time, our study demonstrates no significant differences between systems. These data support the safety and efficacy of performing thrombectomy on monoplane systems and may also carry implications for reducing patient transfer times and potentially increasing thrombectomy access to areas of the world where biplane suites may not be available. The next step would be a prospective randomized trial comparing both systems in different settings.

Review
Multimodal imaging evaluation and clinical progress of spinal osteoblastoma: a comprehensive review.
Spinal osteoblastoma is rare clinically, with insidious onset, atypical symptoms, and various imaging manifestations, which can easily lead to misdiagnosis and delayed diagnosis. It can cause severe neurological dysfunction in patients with intermediate to advanced stages and may easily recur after surgery. ⋯ New clinical approaches such as radiofrequency ablation, radiotherapy, targeted chemotherapy, and other comprehensive treatments have emerged and are progressing rapidly, but no unified norms have yet been developed. This manuscript provides a systematic review of the literature and provides an extensive and comprehensive review of this rare tumor in terms of multimodality imaging manifestations and clinical progress.
