Summary: A 26-year-old male patient with COVID-19 presented with headaches, dizziness, and left hemi-hypoesthesia, and was found to have a large hemorrhage in the right dorsolateral pons due to a pontine cavernous malformation. The patient underwent surgery with a focus on approach selection, anatomic illustrations, and technical nuances, and postoperative clinical course and imaging were reviewed.

Summary: In this article, a novel surgical technique called the purely endoscopic far-lateral supracerebellar infratentorial approach (EF-SCITA) is introduced for resection of posterior clinoid meningioma (PCM), an extremely rare brain tumor. The EF-SCITA approach combines the advantages of the posterolateral approach and endoscopic technique, providing a safe and effective alternative for resection of lesions in the retrosellar space.

Summary: This study describes the technique and feasibility of the purely endoscopic far-lateral supracerebellar infratentorial approach (EF-SCITA) for the treatment of petroclival region meningiomas. The results show that EF-SCITA provides satisfactory exposure and achieves gross total or subtotal resection in most cases with good neurological outcomes. However, cranial nerve deficits and other complications can occur as postoperative complications.

Summary: This article presents a new surgical approach, the extreme lateral supracerebellar infratentorial (ELSI) approach, for treating a large hemorrhagic pilocytic astrocytoma of the superior cerebellar peduncle (SCP). The ELSI approach allows for a wide exposure with direct access to lesions of the SCP, offering excellent surgical angles for median and paramedian lesions. Post-operative MRI showed a good resection outcome.

Summary: This study presents a strategy for effective resection of large falcotentorial meningiomas and compares the efficacy of different surgical approaches. The results show that the paramedian supracerebellar infratentorial and interhemispheric occipital transtentorial approach is effective for resection of complex falcotentorial meningiomas.

Summary: The purely endoscopic far-lateral supracerebellar infratentorial approach (EF-SCITA) offers a safe and effective alternative for resection of retroinfundibular craniopharyngioma (CP), achieving subtotal resection with seemingly low risks of postoperative morbidity. Further observational studies are urgently needed to assess the long-term efficacy of this minimal access approach.

Summary: A male patient in his early 20s presented with diplopia, and imaging showed a hemorrhagic lesion in the pineal region. The patient underwent an endoscopic procedure and successfully had the lesion removed without neurological deficits. Pathological diagnosis revealed a mixed germ cell tumor, and the patient was referred for radiation oncology.

Summary: This study reported the clinical characteristics, surgical treatment, and outcomes of two cases of superior oblique myokymia (SOM) and provided a review of related literature. Microvascular decompression (MVD) using the lateral supracerebellar infratentorial approach was found to be a safe and efficacious treatment for SOM, resulting in immediate and complete resolution of symptoms without recurrence during follow-up.

Summary: The study investigated the incidence of cerebellar venous infarction in the supracerebellar infratentorial approach, finding a risk rate of approximately 0.345%, which may actually be higher. Neurosurgeons should be aware of this potential complication when using this approach and can reduce the risk by preserving more bridging veins.

Summary: This study examined the differences in case characteristics, treatment, and mortality of patients receiving emergency neurosurgery for traumatic brain injury (TBI) across different levels of human development. The study found that the level of human development was associated with mortality, and there was significant variation in mortality between hospitals. Opportunities to improve care globally were identified, including reducing delays to surgery.

Summary: Cerebro-spinal fluid leak after transsphenoidal surgery for pituitary adenomas can be prevented by skull base reconstruction with fat autograft. However, graft changes may interfere with the interpretation of postoperative images. A retrospective analysis of patients who underwent transsphenoidal surgery with fat autograft for skull base reconstruction was performed. It was found that the volume and signal ratio of the fat autograft significantly decreased over time.

Summary: Endoscopic extended transnasal approaches to the apex of the temporal bone pyramid are rapidly developing and widely used worldwide. This article systematizes these approaches and divides them into three large groups based on anatomical relationship with the internal carotid artery. Various modifications are presented to allow for more targeted surgical intervention, minimizing losses and improving patient's quality of life.

Summary: This study aimed to analyze perioperative complications after posterior fossa surgery in pediatric patients and identify associated risk factors. The results showed that emergency surgery, transvermian and telovelar approaches, midline tumor, tumor volume >25 cm3, and surgery performed by a nonspecialized pediatric onconeurosurgeon were independent risk factors for complications.

Summary: Direct electrical stimulation and recording of postauricular muscle response (PAMR) can be used to preserve cochlear nerve and hearing during surgery. Stimulation parameters of 1mA at 1Hz were found to induce cochlear response without affecting other nerves. Most patients maintained stable hearing during the surgery, with some even experiencing significant improvement.

Summary: Corticocortical evoked potentials (CCEPs) have emerged as a valuable intraoperative monitoring technique in eloquent brain tumor surgery, aiding in preserving critical functional areas. Current research shows the potential of CCEPs in guiding surgical decision making, reducing the risk of postoperative neurological deficits, and mapping functional connectivity, but further research and standardization are needed.

Summary: This study aimed to compare the effect of different Modic changes (MC) grades on the cage subsidence rate after spinal interbody fusion surgery. A meta-analysis was conducted on relevant randomized controlled trials and cohort studies. The results showed that MC may be associated with a higher cage subsidence rate. With the increase in MC grades, the incidence of subsidence decreased gradually, but it was always higher than that in the non-Modic changes (NMC). Oblique lumbar interbody fusion may be a better treatment choice for lumbar degenerative disease with MC.

Summary: Early exposure to neurosurgery during medical school is critical for improving recruitment into the specialty. However, about 30% of medical schools in the U.S. lack a neurosurgery program, limiting students' exposure to the field. Virtual education, facilitated by webinars during the pandemic, has advantages such as global outreach and accessibility for international medical students. This review identifies and describes 16 educational resources, serving as a guide for medical students interested in neurosurgery.
