Although various predictors of adverse postoperative outcomes among patients with meningioma have been established, research has yet to develop a method for consolidating these findings to allow for predictions of adverse health care outcomes for patients diagnosed with skull base meningiomas. The objective of the present study was to develop 3 predictive algorithms that can be used to estimate an individual patient's probability of extended length of stay (LOS) in hospital, experiencing a nonroutine discharge disposition, or incurring high hospital charges after surgical resection of a skull base meningioma. ⋯ After external validation, our predictive models have the potential to aid clinicians in providing patients with individualized risk estimation for health care outcomes after meningioma surgery.

Practice consolidation in healthcare has widespread consequences for providers and patients. Although many studies describe this phenomenon in various medical specialties, no such analysis has been performed in neurosurgery specifically. The goal of this study was to assess the trends in the size of U.S. neurosurgery practices over a 5-year period. ⋯ This study shows that over the past 5 years, a substantial trend toward increasing practice sizes has evolved. The effect of the differences in practice size should be examined to determine the large-scale impacts on patient care, payment models, and healthcare access, in addition to neurosurgeon compensation, and satisfaction.

The preoperative assessment of C2 morphology is important for safe instrumentation. Sclerotic changes are often seen in C2 pedicles. Evaluating the diameter measurements solely might not accurately assess the safety of screw insertion. We have proposed a novel grading system of the C2 pedicle that includes sclerosis and evaluated the predictive value of this grading system with the surgeon's safety evaluation. ⋯ We have introduced a novel tool to evaluate the safety of C2 pedicle screw placement. Our results suggest that our pedicle width-sclerosis grading system is reproducible and predicts the surgeon's assessment of safe screw placement better than C2 pedicle diametrical measurements alone.

A novel anterior cervical X-shape-corpectomy and fusion for cervical spinal stenosis at C4-6 level: a technical note.
Anterior cervical corpectomy and fusion (ACCF) is employed in patients with localized cervical spinal stenosis (CSS). However, there are some disadvantages such as subsidence of the titanium mesh cage, slow fusion rates, breakage of the plate and screws, and donor-site complications. For patients with small posterior osteophytes, ossified or hypertrophy of the posterior longitudinal ligaments or ligamentum flavum, the range of decompression from the classic anterior cervical discectomy and fusion (ACDF) cannot meet the clinical requirements. However, employing ACCF is controversial. Therefore, it is necessary to seek a novel, safe and effective surgery that can combine the strengths of ACDF and ACCF. Our objective was to describe a novel anterior approach cervical surgery and investigate its clinical outcomes on segmental CSS at the C4-C6 levels 6 months postoperatively. ⋯ ACXF may be a safe and effective procedure for segmental CSS and an alternative for ACCF, as it has a wide operative field of view, sufficient decompression range, excellent transverse vertebral bony fusion, less internal fixation-related complications, and graft subsidence and no donor-site complications.

Gamma Knife surgery is a complementary procedure to open microsurgery for several indications. However, posttreatment symptomatic complaints are common and often result in short-term follow-up imaging. Here we evaluate the efficacy of repeat brain imaging within 30 days of a Gamma Knife procedure by analyzing the frequency with which that imaging reveals addressable pathology. ⋯ Gamma Knife therapy remains a safe treatment for multiple indications, but it is not risk free and acute symptomatic complaints are common. However, our data suggest that the need for reimaging within 30 days for symptomatic complaints is likely overestimated as obtained imaging does not usually show any change and the rate of significant complication is exceedingly low.
