Direct and/or indirect bypass surgery is the established approach for preventing stroke in patients with moyamoya disease. However, conventional indirect revascularization, including encephalo-myo-synangiosis, has some disadvantages associated with the mass effect of the temporal muscle under the bone flap and postsurgical depression in the temporal region. We devised a novel indirect revascularization method, using only the temporal fascia, to address the aforementioned disadvantages. ⋯ This surgical technique provides good clinical and cosmetic outcomes. It may also be one of the good surgical treatments available for symptomatic moyamoya disease.

Little is known about the effectiveness of recombinant human bone morphogenetic proteins (rhBMPs) in reducing the demand for opioids after surgery. We investigated the association between rhBMP use and the likelihood of achieving opioid independence and changes in opioid demand in the first postoperative year. ⋯ We found no evidence to suggest that rhBMP use during spinal fusion procedures is associated with either the discontinuation or decrease of opioid analgesic therapy. The continued opioid use after surgery warrants further clinical and research attention.

In deep brain stimulation (DBS) surgery, acute high blood pressure (BP) is a risk factor for intracranial hemorrhage. To minimize pain and hypertensive conditions, sufficient local anesthesia is mandatory. We evaluated whether local instillation of anesthetics (LA) or a scalp block (SB) is superior concerning intraoperative hemodynamics and analgesia. ⋯ Our data suggest that SB might be superior to LA for DBS surgery with respect to BP control and hemodynamics. The need for analgesics does not differ substantially between both anesthetic treatment options.

Observational Study
The ebb and flow of neurosurgery in a re-emerging sub-Saharan center. Lessons from consecutive 1025 operated cases and progress models . A prospective observational cohort study.
The evolution of neurosurgery in our center comprises 2 active phases separated by a decade-long latent phase. This study evaluates our experience in the renaissance phase using 1025 cases. We identify paradigms that predict progress under existing practice conditions. ⋯ We found a large unmet neurosurgical load. To resolve this situation, we recommend an increase in the number of training programs for neurosurgery residency. As neurosurgery units evolve, their progress may be evaluated using the NESCAPE (Neurosurgery Care Phase Evolution) paradigm.
