Intraoperative neurophysiological monitoring (IOM) has become valuable in spine surgery. Unfortunately, it is not always available in many spine centers, especially in developing countries. Our aim was to evaluate the accessibility and barriers to IOM in spine surgery in Latin America. ⋯ Despite the fact that 68% of spine surgeons believe IOM to be indispensable for complex spine surgery, cost remains the main barrier to its use/availability in Latin America.

Vascularized nasoseptal flaps allow for the reconstruction of large dural defects and have remarkably reduced the incidence of postoperative complications during endoscopic endonasal skull base surgery. Nevertheless, some complications related to nasoseptal flap have been reported. Flap necrosis is a rare, but serious issue is associated with meningitis and cerebrospinal fluid (CSF) leak. ⋯ Our case suggested that partial rather than total flap necrosis could occur, possibly due to variances of vascular anatomy, leading to focal ischemia. Debridement of the necrotic region may be an important solution for recurrent cerebrospinal leakage secondary to partial necrosis of a nasoseptal flap.

The volume and spectrum of neurosurgical procedures being performed during the coronavirus disease 2019 (COVID-19) pandemic have significantly changed as compared to the pre-COVID-19 period. The objective of this study is to examine this change and draw useful conclusions. ⋯ This paper highlights the drastic reduction in the operative workflow and the outpatient clinic workflow during the ongoing corona pandemic which will have significant collateral damages in the long run. We will have to strike the right balance between providing our patients with the best medical treatment while limiting the spread of the COVID-19 infection.

Severe traumatic brain injury (TBI) is a significant cause of death and disability. The objective of this study was to provide an overview of whether adherence to brain trauma foundation (BTF) guidelines improved outcomes following TBI utilizing intracranial pressure (ICP) monitoring. ⋯ Adherence rates to BTF guidelines for ICP monitoring in patients with severe TBI were low. Further, these rates varied across centers and were correlated with higher mortality and morbidity rates. Although ICP insertion may be an indicator of TBI severity, the current BTF criteria for insertion of ICP monitors may fail to identify patients likely to benefit.

In this paper, we report a clinical series of skull base lesions operated on trough the MiniPT, extending its application to skull base lesions, either using the classical minipterional or a variant, we call extradural minipterional approach (MiniPTEx). ⋯ We further advance the indications of the MiniPT by extending it to operate on the cranial base tumors or complex vascular lesions without additional morbidity. MiniPT approach may be safely associated with skull base techniques, including anterior and posterior clinoidectomies, peeling of the middle fossa, transcavernous approach, and anterior petrosectomy. The versatility of the MiniPT craniotomy and the feasibility of performing skull base surgery through the MiniPT technique have been demonstrated in this paper.
