Symptomatic Progression, Recurrence, and Long-Term Follow-Up of Patients With Intracranial Epidermoid Cysts.

Background And Objectives: Intracranial epidermoid cysts are rare, slow-growing but highly recurrent tumors with incompletely understood symptoms, progression, complications, and outcomes. The aim of the study was to characterize the symptomatology, surgical management, and long-term outcomes of these tumors.

Methods: This single-center retrospective analysis identified patients with pathologically confirmed intracranial epidermoid cysts from 1989 to 2023.

Design, fabrication, and testing of a new soft-pouch robot with 6 degrees of freedom to expand the reach of open and endonasal skull base approaches.

Objective: Most robots currently used in neurosurgery aid surgeons in placing spinal hardware and guiding electrodes and biopsy probes toward brain targets. These robots are inflexible, cannot turn corners, and exert excessive force when dissecting and retracting brain tissue, limiting their applicability in cranial base surgery. In this study, the authors present a novel soft-pouch robot prototype driven by compressed air and capable of gentle tissue manipulation.

Interhemispheric axonal sprouting occurs after pial removal in mice.

White matter lacks the kind of plasticity that is present in the cortex, and subcortical injuries often result in permanent neurological deficits. Because cortical regions share common subcortical nuclei, creating new intergyral connections may allow for the bypass of subcortical damage. In this manuscript, a surgical interhemispheric bridge is created in mice, providing a model for an intercortical transpial bypass.
