A long-term follow-up is reported. Surgical management of coexisting ACs and CM-1 should not aim at the complete resolution of the cyst or of tonsil herniation, especially when pediatric patients are treated. Rather, the purpose of the neurosurgeon should be to understand the underlying pathogenic mechanism, and then restoring both the cerebrospinal fluid flow in the posterior fossa and the dynamic equilibrium between ventricles, cyst, and subarachnoid space.

In microneurosurgery, the operating microscope plays a vital role. The classical neurosurgical operation is bimanual, that is, the microsurgical instruments are operated with both hands. Often, operations have to be carried out in narrow corridors at the depth of several centimeters. With current technology, the operator must manually adjust the field of view during surgery-which poses a disruption in the operating flow. Until now, technical adjuncts existed in the form of a mouthpiece to move the stereo camera unit or voice commands and foot pedals to control other interaction tasks like optical configuration. However, these have not been widely adopted due to usability issues. This study tests 2 novel hands-free interaction concepts based on head positioning and gaze tracking as an attempt to reduce the disruption during microneurosurgery and increase the efficiency of the user. Technical equipment included the Pentero 900 microscope (Carl Zeiss Microscopy GmbH, Jena, Germany), HTC Vive Pro (HTC, Taoyua at the Charité Hospital in Berlin found that the gaze-tracking and head-positioning- based microscope adjustment were 18% and 29% faster, respectively, than the classical bimanual adjustment of the microscope. Focused user interviews showed the users' proclivity for the new interaction concepts, as they offered minimal disruption between the simultaneous target selection and camera position adjustment. The hands-free interaction concepts presented in this study demonstrated a more efficient execution of the microneurosurgical tasks than the classical manual microscope and were assessed to be more preferable by both residents and consultant neurosurgeons.

The novel coronavirus disease 2019 (COVID-19) pandemic has been at its peak for the past 8 months and has affected more than 215 countries around the world. India is now the second most-affected nation with more than 48,000,000 cases and 79,000 deaths. Despite this, and the fact that it is a lower-middle-income nation, the number of deaths is almost one third that of the United States and one half that of Brazil. However, there has been no experience published from non-COVID-19-designated hospitals, where the aim is to manage noninfected cases with neurosurgical ailments while keeping the number of infected cases to a minimum. We analyzed the number of neurosurgical cases (nontrauma) done in the past 5 months (March-July 2020) in our institute, which is the largest neurosurgical center by volume in southern India, and compared the same to the concurrent 5 months in 2019 and 5 months preceding the pandemic. We also reviewed the total number of cases infected with COVID-19 managed during this time. We opeanage
