ObjectiveAugmented reality (AR) and virtual reality (VR) technologies have been introduced to neurosurgery with the goal of improving the experience of human visualization. In recent years, the application of remote AR and VR has opened new horizons for neurosurgical collaboration across diverse domains of education and patient treatment. Herein, we aimed to systematically review the literature about the feasibility of this technology and discuss the technical aspects, current limitations, and future perspectives.MethodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 4 databases (PubMed, Embase, Scopus, and Cochrane Library) were queried for articles discussing the use of remote AR and VR technologies in neurosurgery. Data were collected in various fields, including surgery type, application type, subspecialty, software and hardware descriptions, haptic device utilization, visualization technology, internet connection, remote site descriptions, technical outcomes, and limitations. Data were summarized as counts and proportions and analyzed using IBM SPSS software.ResultsOur search strategy generated 466 records, out of which 9 studies satisfied the inclusion criteria. The majority of AR and VR applications were used in cranial procedures (77.8%), mainly in education (63.6%), followed by telesurgical assistance (18.2%), patient monitoring (9.1%), and surgical planning (9.1%). Local collaborations were established in 55.6% of the studies, while national and international partnerships were formed in 44.4% of the studies. AR was the main visualization technology, and 3G internet connection was predominantly used (27.5%). All studies subjectively reported the utility of remote AR and VR for real-time interaction. The major technical challenges and limitations included audiovisual latency, the requirement for higher-fidelity and resolution image reconstructions, and the level of proficiency of the patient with the software.ConclusionsThe results from this systematic review suggest that AR and VR technologies are dynamically advancing to offer remote collaboration in neurosurgery. Although still incipient in development and with an imperative need for technical improvement, remote AR and VR hold a frontierless potential for patient monitoring, neurosurgical education, and long-distance surgical assistance.Copyright © 2024 Elsevier Inc.
