We analyzed cortical landmarks, trajectory of approach, and various fiber tracts in the vicinity of our earlier described approach through the orbital/basal surface of the frontal lobe to access tumors located in the region of the caudate nucleus. We also present a new lateral orbital trajectory to approach these tumors. ⋯ Surgical approach to the caudate head through the orbital surface of the frontal lobe as described by us provides the shortest trajectory and safe surgical route to access tumors of the caudate nucleus.

Meningiomas of the cavernous sinus (CS) present a neurosurgical challenge. The anatomic complexity of the area can create a potential for injury to neurovascular structures. This has traditionally limited total tumor removal. ⋯ CS surgery for meningioma is feasible with low morbidity and can provide benefits in improving preexisting cranial nerve dysfunction (Video 1).1-4 Complete resection of the CS meningiomas is possible in most cases. CS tumors remain a surgical challenge, but accurate knowledge of surgical neuroanatomy and surgical approaches facilitates their safe and effective treatment. The patient gave informed consent for surgery, use of images, and video publication.

To emphasize the importance of vertebral artery (VA) mobilization by reviewing the anatomy and variations of the VA while performing total resection of VA-associated tumors that develop from different tissues. ⋯ VA mobilization reduces the need for instrumentation in VA-related cases, especially nerve tumors, and increases the possibility of the surgical resection of vertebral tumors.

The NeVa M1 thrombectomy device is a novel hybrid-cell stent retriever with multifunctional zones for optimized retrieval of resistant clots located in the M1 segment of the middle cerebral artery. The objective was to evaluate the safety and efficacy of the NeVa in a "real-life" setting. ⋯ The NeVa M1 provides a high first-pass complete reperfusion rate with an adequate safety profile. To retrieve resistant clots, the stent design exerts high mechanical traction forces, which may trigger vasospasm and vessel wall damage. Large, comparative studies are warranted to draw a definite conclusion on this device.

In the wake of the COVID-19 pandemic, the Centers for Medicare & Medicaid Services (CMS) has recommended the temporary cessation of all elective surgeries. The effects on patients' interest of elective neurosurgical procedures are currently unexplored. ⋯ With the recommendation for cessation of elective surgeries, patient interests in overall elective neurosurgical procedures have dropped significantly. With gradual reopening, there has been a resurgence in some procedure types. Google Trends has proven to be a useful tracker of patient interest and may be used by neurosurgical departments to facilitate outreach strategies.
