SURG-03. VIRTUAL REALITY ASSISTANCE IN THE MANAGEMENT OF PEDIATRIC BRAIN TUMORS

Abstract

Abstract BACKGROUND Virtual reality (VR) solutions are emerging as a useful adjunct to the armamentarium of the neurosurgeon. Surprisingly, little data is available in the literature regarding its utility in pediatric neurosurgical oncology. We hereby report our preliminary Institutional experience on the application of VR to surgical rehearsal in a series of pediatric brain tumors. METHODS Virtual models were obtained by the Surgical Planner (Surgical Theatre, Inc) in a series of 50 consecutive brain tumor cases treated at Bambino Gesù Children’s Hospital. Utility of VR was scored based on operators’ perception. Explored items included: planning, execution, resection, sparing of eloquent tissue, and overall surgical management. Scoring was performed using a customized Likert scale. RESULTS We prospectively collected 100 consecutive questionnaires from surgeons participating to brain tumor resection procedures. In a multivariate analysis VR was found to be significantly more beneficial in specific surgical settings. Leading surgeons (LS) judged VR significantly more useful in supratentorial tumors, in children younger than 10 years, and in planned partial resections. Assistant surgeons (AS) found VR more useful in supratentorial lesions, particularly in deep seated tumors. Both LS and AS perceived VR to be less useful for in embryonal tumors and epilepsy-associated gliomas (LEAT). CONCLUSIONS Our data suggest that VR technology is useful in the surgical management of children with brain tumors. There might be specific clinical scenarios in which the advantage of VR availability might have a significant clinical impact in planning and performing surgical resection.
