Abstract

Background

Immersive virtual reality (iVR) facilitates surgical decision-making by enabling surgeons to interact with complex anatomic structures in realistic 3-dimensional environments. With applications in clinical, research, and teaching settings, its effects on patient- and surgeon-specific outcomes should be clarified. This systematic review examines the current literature on iVR for patient-specific preoperative planning.

Materials And Methods

A literature search was performed on MEDLINE, EMBASE, CENTRAL, Web of Science, and Scopus for relevant publications from January 1, 2000 through March 21, 2021. Two reviewers independently screened titles, abstracts, and full texts, extracted data, and assessed quality using the Quality Assessment Tool for Studies with Diverse Designs (QATSDD). Results were qualitatively synthesized, and descriptive statistics were calculated.

Results

The systematic search yielded 2,555 studies in total, with 24 full-texts subsequently included for qualitative synthesis, representing 264 medical personnel and 460 patients. Neurosurgery was the most frequently represented discipline (10/24; 42%). Preoperative iVR did not significantly improve patient-specific outcomes of operative time, blood loss, complications, and length of stay, but may decrease fluoroscopy time. In contrast, the impact of iVR on surgeon-specific outcomes of surgical strategy, anatomy visualization, and confidence was statistically significant. Validity, reliability, and feasibility of patient-specific iVR models were assessed as well. The mean QATSDD score of included studies was 32.9%.

Conclusions

Immersive VR improves surgeon experiences of preoperative planning, with minimal evidence for impact on short-term patient outcomes. Future work should focus on large, high-quality studies investigating long-term patient outcomes, and utility of preoperative iVR for trainees.
