Virtual Reality in Awake Surgery : Pilot Study VIRAS
Sponsor: University Hospital, Brest
Summary
The VIRAS (Virtual Reality in Awake Surgery) project is a two-stage, adaptive study. Its goal is to demonstrate the tolerance of the virtual reality (VR) headset for performing cognitive neuro-monitoring during awake brain surgery. Awake surgery involves operating on patients who remain conscious during the procedure and is most commonly employed in interventions such as tumor resections and epilepsy treatments. This approach allows surgeons to monitor and preserve critical brain functions by engaging the patient in real-time assessments of motor, sensory, and cognitive capabilities. The use of immersive distractions such as VR can help reduce anxiety and discomfort during awake craniotomy. In order to control the risks as well as possible, the investigators have tested the equipment on patients who will undergo orthopedic surgery under local anesthesia at the hospital of Brest (Saliou V, Dardenne G, Panheleux C, Le Vourc'h F, Bleunven J, Maoudj I, Longo B, Dubrana F, Yvinou A, Fernandez M, Consigny M, Nowak E, Guellec D, Seizeur R. Virtual Reality in Awake brain Surgery (VIRAS) stage I: Proof of concept and tolerance validation during scheduled orthopedic surgery. PLoS One. 2025 Sep 3;20(9):e0329894. doi: 10.1371/journal.pone.0329894. PMID: 40901801; PMCID: PMC12407469.) The second part of the project; the equipment is tested on patients wich undergo neurosurgery in awake condition, using the same equipment and procedures as in the orthopedic cohort. An additional element will be the integration of a dedicated software application for the selection and control of neurofunctional tests. This application relies on an algorithm that incorporates both lesion laterality and tumor location, enabling dynamic adaptation of the test sequence.

Conditions
Interventions
Training session with the virtual reality mask
Patients will have a training session with the virtual reality mask, the day before surgery. The training consists in the realization, by the patient, of a series of language or neuropsychological tests and evaluation of the acceptability of the device by the patient with Visual Analog Scale (device tolerance from 0 (intolerable) to 10 (completely tolerated)).
Monitoring of the device
In the operating room : installation and per-operative monitoring of the device. If the device was removed, the list of device side effects or surgery-related adverse events that was required discontinuation of the device will be established.
Acceptability of the device
After the surgery: evaluation of the acceptability of the device by the patient with Visual Analog Scale (device tolerance from 0 (intolerable) to 10 (completely tolerated))
Patient state of anxiety
Assessing patient's state of anxiety with the State-Trait Anxiety Inventory (STAI) after surgery.
