Minimally invasive surgery of small skull base meningiomas is technically challenging. We report the role of endoscopic 5-aminolevulinic acid fluorescence guidance (e-5-ALA-FGS) for small and deep-seated anterior skull base meningiomas. ⋯ Endoscopic 5-ALA fluorescence guidance was shown to be feasible when resecting small and deep-seated skull base meningiomas via minimally invasive approaches. Based on this proof of principle, we encourage its evaluation for the middle or posterior fossa (e.g., internal auditory canal) and other difficult areas (e.g., behind neurovascular structures or the brainstem). The sensitivity and specificity of this method should be prospectively and systematically investigated.

The use of Gamma Knife radiosurgery (GKRS) for recurrent or residual vestibular schwannoma (VS) after microsurgery (MS) has been investigated in several retrospective studies. The purpose of this study was to identify potential risk factors for both neurologic deterioration and tumor progression after GKRS for previously operated VSs in a prospective setting. ⋯ Intended submaximal resection followed by GKRS is a viable treatment for VS. Because tumor remnant size after MS is an important predictor for recurrence after adjuvant GKRS, both brainstem and cerebellar decompression and maximal safely achievable resection should remain major goals of microsurgery.

A broad armamentarium of microsurgical techniques affords flexibility to surgeons when choosing a procedure that is best tailored to fit the anatomy of an individual. Herein, we report on the feasibility of using the deep cervical artery (DCA) to revascularize the vertebral artery (VA) via a DCA-V3 bypass graft. ⋯ Based on the mean diameter of the DCA reported in extant literature and this study, the blood flow volume of the DCA makes it a viable candidate to bypass the proximal VA.

Cervical sagittal imbalance compromises health-related quality of life and can lead to myriad incapacitating symptoms through compression of the spinal cord. Questions regarding which parameters play primary roles in the progression of cervical sagittal imbalance and which might be compensatory factors remain unanswered. ⋯ BMI, OS, C0C2, CL, and TS were primary influencers in the progression of cervical sagittal imbalance and established a predictive equation of asymptomatic population, which can provide clinical advice and remind surgeons of the primary influencers of reconstructive surgery for better prognoses.

To describe neurosurgical patient and caregiver perceptions of provider communication, the impact of patient education, and their understanding of information given to them throughout the neurosurgical care trajectory. ⋯ Our study describes several unmet needs, finds inconsistencies in how information is delivered and a lack of patient-centered and caregiver-centered approaches to communication. Neurosurgery groups should identify unmet needs at their institution and implement strategies and interventions to improve the patient and caregiver experience.
