Middle meningeal artery (MMA) embolization is an emerging minimally invasive endovascular technique for chronic subdural hematoma (cSDH). Currently, limited literature exists on its safety and efficacy compared with conventional treatment (open-surgical-evacuation-only). ⋯ There was a trend for lower recurrence and mortality rates in the embolization era cohort. There were significantly higher radiological improvement rates on last follow-up in the surgical only cohort era. There were no significant differences in complications and clinical improvement.

Letters of recommendation (LORs) are one of the most important components of the neurosurgical residency application. Studies in other fields and surgical subspecialties have found gender bias. ⋯ Overall, there are more similarities than differences between genders in LORs for neurosurgical applicants. This finding is at odds with what has previously been reported in most other surgical specialties.

Meta Analysis
External Lumbar Drainage following Traumatic Intracranial Hypertension: A Systematic Review and Meta-Analysis.
Traumatic brain injury (TBI) often results in elevations in intracranial pressure (ICP) that are refractory to standard therapies. Several studies have investigated the utility of external lumbar drainage (ELD) in this setting. ⋯ Given preliminary data indicating potential safety and feasibility in highly selected cases, the use of ELD in adults with severe TBI and refractory intracranial hypertension in the presence of open basal cisterns and absence of large focal hematoma merits further high-quality investigation; the ideal conditions for potential application remain to be determined.

Meta Analysis
Complications of Cranioplasty in Relation to Material: Systematic Review, Network Meta-Analysis and Meta-Regression.
Cranioplasty is a ubiquitous neurosurgical procedure consisting of reconstruction of a pre-existing calvarial defect. Many materials are available, including polymethylmethacrylate in hand-moulded (hPMMA) and prefabricated (pPMMA) form, hydroxyapatite (HA), polyetheretherketone (PEEK) and titanium (Ti). ⋯ PEEK appears to have the lowest risk of cranioplasty revision, but further research is required to determine the optimal material.
