Comparative StudyOlfactory groove meningiomas: supraorbital keyhole versus orbitofrontal, frontotemporal, or bifrontal approaches.
Olfactory groove meningiomas (OGMs) often require surgical removal. The introduction of recent keyhole approaches raises the question of whether these tumors may be better treated through a smaller cranial opening. One such approach, the supraorbital keyhole craniotomy, has never been compared with more traditional open transcranial approaches with regard to outcome. In this study, the authors compared clinical, radiographic, and functional quality of life (QOL) outcomes between the keyhole supraorbital approach (SOA) and traditional transcranial approach (TTA) for OGMs. They sought to examine the potential advantages and disadvantages of open/TTA versus keyhole SOA for the resection of OGMs in a relatively case-matched series of patients. ⋯ The keyhole SOA was associated with a statistically significant decrease in LOS and less postoperative edema relative to traditional open approaches.

A novel radiological classification of midbrain pilocytic astrocytomas and its implication for surgical management: a single-institution experience of 57 cases.
Surgery for midbrain pilocytic astrocytoma (PA) remains a formidable challenge. To facilitate decision-making and achieve a better outcome in the management of patients with midbrain PA, the authors have proposed a novel radiological classification of midbrain PAs with long-term follow-up. ⋯ A novel and comprehensive radiological classification of midbrain PAs was established, which will serve as a valuable tool in patient management and promote uniform communication and comparison across different studies and publications.

Template-based target point localization for occlusion of the middle meningeal artery during evacuation of space-occupying chronic subdural hematoma.
Endovascular middle meningeal artery (MMA) occlusion may help reduce the risk of recurrence after burr hole evacuation of chronic subdural hematoma (cSDH) but carries an additional periprocedural risk and remains hampered by logistical and financial requirements. In this study, the authors aimed to describe a simple and fast technique for preoperative MMA localization to permit burr hole cSDH evacuation and MMA occlusion through the same burr hole. ⋯ A template-based target point approach for MMA localization may serve as a simple, fast, reliable, and cost-effective technique for surgical evacuation of space-occupying cSDHs with MMA obliteration through the same burr hole in a single setting.

Localized focal cortical dysplasia type II: seizure freedom with lesionectomy guided by MRI and FDG-PET.
The authors perform thorough, noninvasive presurgical evaluations for intractable epilepsy at their center and avoid unnecessary intracranial EEG when possible. The purpose of this study was to clarify the appropriateness of their lesion-oriented surgical strategy for localized focal cortical dysplasia (FCD) type II. ⋯ In most of the patients with localized FCD type II, MRI and/or FDG-PET detected the localized abnormality. Lesionectomy without intracranial EEG led to seizure freedom in most cases. Even when lesions were in the vicinity of eloquent areas, seizure and functional outcomes were favorable. Intraoperative ECoG may thus be unnecessary. Complete resection of the lesion is essential for favorable seizure outcome in MRI-positive patients. In MRI-negative patients, surgery with intracranial EEG guided by FDG-PET provided seizure-free outcomes.

Observational StudySame-day discharge after craniotomy for tumor resection: a retrospective observational single-center study of 630 patients.
Modern neurosurgical developments enable minimally invasive surgery with shorter operation times, faster recovery, and earlier hospital discharge. These in combination with Enhanced Recovery After Surgery (ERAS) protocols have the potential to safely shift craniotomy for tumor resection to the ambulatory setting in selected patients. The aim of this retrospective observational single-center study was to assess the success rate of planned same-day discharge from hospital in patients undergoing craniotomy for supratentorial brain tumor resection under general anesthesia or awake craniotomy as well as to explore potential associations with anesthesia techniques, complications, and readmission rates. ⋯ This retrospective, single-center analysis shows that same-day discharge after craniotomy can be safe in carefully selected patients after both GA and AC for tumor resection. Multidisciplinary involvement (surgeons, anesthesiologists, nurses, and other allied health professionals) optimizes success of same-day craniotomy programs. Future optimization of analgesia and prevention of PONV has the potential to increase the success rate.
