There has been a significant expansion in endonasal endoscopic skull base surgery (EES) that has been used to address a wide range of intracranial and sinonasal pathologies. Although there exists a large amount of literature on approaches and patient outcomes, there is a paucity of data describing ergonomics in this field. Our goal was to evaluate and summarize the literature on ergonomics in EES. ⋯ There are several improvements in EES ergonomics that can decrease fatigue, improve efficiency, and overall surgeon well-being.

Preoperative testing and evaluation for coronavirus disease 2019 (COVID-19) have been an enigmatic challenge for the neurosurgical community during the pandemic. Since the beginning of the pandemic, laboratory diagnostic methods have evolved substantially, and with them has been the necessity for readily available, fast, and accurate preoperative testing methods. ⋯ Through this review, we highlight the guiding principles for preoperative testing, which may serve as a road map for other medical institutions to follow. In addition, we provide an Indian perspective of preoperative testing and share our experience in this regard.

Mass casualty incidents (MCIs) due to bombing-related terrorism remain an omnipresent threat to our global society. The aim of this study was to elucidate differences in blast injury patterns between military and civilian victims affected by terrorist bombings. ⋯ Though the increased number of head/neck injuries was unexpected, we also found that the number of nonlethal head injuries also increased, predicating that more military blast neurotrauma patients survived their injuries. These data can be used to increase blast MCI preparation and education throughout the international neurosurgical community.

The study of brain connectomics has led to a rapid evolution in the understanding of human brain function. Traditional localizationist theories are being replaced by more accurate network, or hodologic, approaches that model brain function as widespread processes dependent on cortical and subcortical structures, as well as the white matter tracts (WMTs) that link these areas. Recent surgical literature suggests that WMTs may be more critical to preserve than cortical structures because of the comparably lower capacity of recovery of the former when damaged. ⋯ The dominant-hemisphere language WMTs have been mapped using picture naming, semantic association, word repetition, reading, and writing tasks. For monitoring of vision and spatial functions, the modified picture naming and line bisection tasks, as well as the recording of visual evoked potentials, have been used. Repetitive movements and monitoring of motor evoked potentials and involuntary movements have been applied for preservation of the motor networks.

Brain plasticity is an ongoing process of reorganization not only on the macroscopic level but also from underlying changes at the cellular and molecular levels of neurons. This evolution has not yet been fully understood. The objective of this paper is to review and understand neuroplasticity through the review of literature, imaging, and intraoperative evidence.
