In the treatment of Chiari malformation type I (CM-I), posterior fossa decompression is achieved via suboccipital craniectomy (SOC); however, some patients continue to experience symptoms after treatment, which may be due to craniocervical instability (CCI). The purposes of this study were to analyze data from patients who required an occipitocervical fusion (OCF) for the management of CCI after having previously undergone SOC for CM-I to determine if OCF is a safe and effective option and to determine any identifiable risk factors for CCI in these patients. ⋯ Symptomatic CCI should be recognized as a delayed postoperative complication in the surgical treatment of CM-I, with an underlying connective tissue hypermobility disorder such as EDS serving as a potential risk factor its development. CCI can be managed with OCF as a safe and effective treatment option for this patient population.

The intermediate condylar canal, which lies lateral to the occipital condyles and medial to the jugular foramen, is rarely mentioned in textbooks, even those devoted to the skull base. Therefore the present anatomic study was performed to better elucidate these structures. ⋯ Knowledge of the anatomic variants at the base of the skull may help minimize complications during surgical procedures that employ a paracondylar or transcondylar approach or approaches to the jugular foramen.

To describe recent trends in treatment and outcomes of endovascular coil embolization and microsurgical clipping treatment strategies for ruptured intracranial aneurysms. ⋯ Analysis revealed no difference in 1-year mortality between coiling and clipping. Clinical outcomes, including intensive care, surgical complications, and vasospasm, favored coiling regardless of aneurysm location. Patients with coiling of anterior communicating artery aneurysms had significantly less hydrocephalus and patients with coiling of posterior communicating artery aneurysms had substantially less vasospasm treatment within 1 year compared with the clipping cohort.

The UK neurosurgical community has a track record of delivering high-quality, practice-changing clinical research studies, facilitated by a robust clinical research infrastructure and close collaborations between neurosurgical centers. More recently, these large-scale studies have been conceived, developed, and delivered by neurosurgical trainees, working under the umbrella of the British Neurosurgical Trainee Research Collaborative (BNTRC). ⋯ Importantly, we focus on our experience of trainee-led studies, including the development of the network, current challenges, and future directions. We believe that a similar model can be applied in different settings and countries, which will drive up the quality of neurosurgical research, ultimately benefiting future neurosurgical patients.

The practice of neurosurgery has been profoundly affected by the coronavirus disease 2019 (COVID-19) pandemic in Kazakhstan. Many elective surgeries were postponed or canceled, which resulted in difficulties in hospitalization. In the present study, we aimed to describe the effects of COVID-19 on neurosurgical practice and to determine whether a discrepancy was present in the effects between metropolises and regional cities in Kazakhstan. ⋯ The true effect of the pandemic remains unknown for Kazakhstan. A discrepancy between the metropolitan and regional cities was found in the present study. Efforts are required and relevant guidelines must be developed to ensure that the neurosurgical treatment of various conditions continues to be available during health emergencies and that the disparities are addressed.
