Radiographic characterization of Chiari malformation (CM) has historically focused on caudal tonsillar herniation (CH) below the foramen magnum. Previously, we published evidence linking ventral tonsillar herniation (VH) and medullary symptoms in very young children. We sought to extend that investigation by studying the radiographic and clinical significance of VH in adults diagnosed with CM. ⋯ VH is relatively common in CM patients and might be an important independent radiographic metric to evaluate and consider as part of the decision-making process, especially in those presenting with Chiari-like symptomatology referable to the medulla but who do not meet the traditional criteria of cerebellar ectopia greater than 5 mm.

Although much research has examined nursing and physician burnout, the advanced practice provider (APP) population has not yet been studied. The goal of the present study was to survey APPs in neurosurgery to determine whether greater emotional intelligence (EI) is protective against burnout. ⋯ For neurosurgical APPs, EI is protective against burnout. Many opportunities exist at the individual and organizational level to alleviate burnout among neurosurgical APPs. Targeted strategies to improve work-life balance, EI, support systems, and opportunities for career development among neurosurgical APPs might enhance employment satisfaction and reduce burnout.

Resection of pure intraorbital tumors is challenging owing to the nearness of the optic apparatus. The objective of this article was to report our experience with different intraorbital tumors and discuss classic approaches and obstacles. ⋯ Considering the low operative morbidity and satisfactory functional outcome, gross total resection of intraorbital lesions is feasible. We support use of classic transcranial and transorbital approaches. More invasive and complicated approaches were not needed in our series.

Familial forms of cavernous malformations (CMs) often occur as multiple lesions. Nevertheless, the presence of a single CM does not exclude the familiarity. The aim of this study is to establish which patients who undergo surgery for a single cerebral cavernous malformation (CCM), with no family history at initial diagnosis, should be investigated for familiarity through genetic testing and counseling. ⋯ Patients with CCM and no known family history at the time of the initial diagnosis who present specific features should be studied by genetic screening. The Ki67 MIB1 is a useful biomarker in favor of familial occurrence and may be studied in all patients with CMs to define the indication to the genetic tests.

To develop preventive strategies against postoperative infarction after indirect revascularization surgery in patients with moyamoya disease (MMD), we evaluated clinical information, with a specific focus on the imaging pattern of postoperative infarction. ⋯ Local cortical irritation, hemodynamic fluctuation, and thromboembolic events were suggested as possible mechanisms of postoperative infarction after indirect revascularization in patients with MMD. Minimizing cortical irritation, maintaining adequate cerebral blood flow, and perioperative antiplatelet agents might decrease the incidence of postoperative infarction.
