Resection and Defect Repair of Oral Cancer Aided by Mixed Reality Technology
China30 participantsStarted 2026-04-01
Plain-language summary
The objective of this exploratory clinical trial is to apply Unreal Engine 5 (UE5)-based Mixed Reality (MR) technology to achieve real-time stereoscopic visualization of surgical planning, personalized free flap harvest and defect reconstruction, accurate oral cancer resection, and precise morphological and volumetric matching of the reconstructed free flap to the defect site.
Researchers adopted a parallel controlled design, with participants randomized into three groups: Experimental Group 1 (undergoing Mixed Reality \[MR\] technology-assisted surgery), Experimental Group 2 (undergoing virtual surgical guide-assisted surgery), and Control Group (undergoing conventional surgery). A total of 30 participants will be recruited, with 10 cases in each group.
The primary purpose is to confirm the effectiveness of MR technology in assisting oral cancer resection, free flap design, harvest, and defect reconstruction. Allocation concealment will be implemented via the sealed envelope method.

Inclusion criteria
. Definite pathological diagnosis of oral cancer before surgery;
. Defects suitable for free flap reconstruction;
. Patients have signed the informed consent form and are willing to cooperate with postoperative follow-up.
Exclusion criteria
Exclusion Criteria (After Enrollment)
. Violation of important inclusion criteria;
. Subjects did not receive surgical treatment;
. No observation data after randomization. Withdrawal Criteria Withdrawal of subjects from the trial refers to cases where enrolled subjects are determined by the investigator to withdraw from the trial due to conditions that make it inappropriate to continue the trial. In accordance with the informed consent form, subjects have the right to withdraw from the trial midway. Subjects who do not explicitly propose to withdraw but stop receiving treatment and tests and are lost to follow-up are also considered "withdrawn" (or "lost to follow-up"). The reason for withdrawal should be understood and recorded as much as possible, such as: poor subjective curative effect; inability to tolerate certain adverse reactions; inability to continue participating in the clinical study due to personal reasons; economic factors; or lost to follow-up without stating the reason.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
