This study introduces a new electrosurgical simulation for oral cancer resection training. The tool provides objective metrics to assess surgeon skills, improving patient outcomes and surgical safety.
Area of Science:
- Surgical Simulation
- Medical Education Technology
- Oral Oncology
Background:
- Oral cancer resection quality is vital for patient survival and local control.
- Existing simulators lack objective feedback or electrosurgery compatibility.
- A novel simulation task was developed to address these limitations.
Purpose of the Study:
- To develop and validate an electrosurgical simulation task for oral cancer resection.
- To provide objective, quantitative metrics for assessing surgical performance.
- To enhance simulation-based training for improved patient outcomes.
Main Methods:
- A plant-derived soft tissue model compatible with electrosurgery was utilized.
- Quantitative metrics included margin error distance and tumor bed carbonization degree.
- Validity was assessed through expert surgeon questionnaires and performance comparisons (experts vs. novices).
Main Results:
- The simulation task received high expert evaluations (4.4/5) for realism and metrics (4.8/5).
- Experts demonstrated significantly better performance than novices, with smaller margin errors (0.79 mm vs. 2.45 mm) and lower carbonization (ΔE: 2.33 vs. 8.70).
- The quantitative measures showed good internal consistency (Cronbach's alpha: 0.803).
Conclusions:
- The developed simulation task is user-friendly, electrosurgery-compatible, and offers objective performance metrics.
- It serves as a practical tool for formative feedback in simulation-based surgical training.
- This technology can improve the quality of oral cancer resection and patient outcomes.

Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
