Access to timely neurosurgical care in particular remains limited worldwide, and is associated with increased morbidity and mortality, a decrease in overall life expectancy, and catastrophic economic costs. To date, access to neurosurgical care has not been completely studied and reported in the Caribbean neurosurgical literature. In this study, we aim to understand the geographic distribution of hospital facilities with neurosurgical capacity among the CARICOM member states to determine timely access to neurosurgical care. ⋯ Timely access to care is an important tenet of global neurosurgery. We found that 3.5 million Caribbean residents are outside of the access zone to neurosurgical capacity. Public health advocates, governments, providers, and patients should be aware of the inequity in access to neurosurgical care and should collectively work to close the gap.

Microvascular decompression (MVD) is the most effective treatment for hemifacial spasm (HFS). However, surgical difficulties due to complex anatomy or revision surgery can endanger the functional integrity of the brainstem. We describe surgically challenging cases and provide operative guidance that may be helpful for neurosurgeons who perform MVDs. ⋯ Complex or unusual HFS types carry higher surgical risks in MVD. Neurosurgeons performing MVDs need to be prepared to manage complex HFS cases in order to achieve favorable clinical outcomes.

Meningiomas are the most frequent primary brain tumors. The long-term natural history of asymptomatic meningiomas remains unclear and difficult to predict accurately, however. The purpose of this study was to determine the subsequent course of asymptomatic meningiomas preceded by 5 years of no treatment. ⋯ The present study revealed the subsequent course of asymptomatic meningiomas after 5 years of no treatment and demonstrated that 5y-TdT is useful to detect patients who may require treatment.

To investigate the risk factors for increased surgical drain output after transforaminal lumbar interbody fusion (TLIF). ⋯ This study showed that older age, smoking, more fused levels, and intraoperative end plate injury were the independent risk factors, while administration of TXA was a protective factor for increased surgical drain output after TLIF.

We performed a retrospective cohort study to investigate the prevalence of and risk factors for asymptomatic spondylotic cervical spinal stenosis (ASCSS) in the setting of lumbar spinal stenosis (LSS). ⋯ Our findings suggest that an LLA >35.85° and a DCSA <84.50 mm2 are risk factors for the development of ASCSS. For LSS patients with an enlarged LLA and reduced DSCA, a whole spinal magnetic resonance imaging examination should be performed.
