Isolated Cephalic Perfusion via Aortic Occlusion for Cervicofacial Simulation: Validation of a High‐Fidelity Cadaveric Model

OBJECTIVE: High-fidelity simulation may improve surgical training in head and neck surgery, yet validated perfused cadaveric models remain scarce. We evaluated the face, content, and construct validity of a perfused cadaveric model using isolated cephalic perfusion for cervicofacial surgical simulation. STUDY DESIGN: Prospective validation study of a reperfused cadaveric model using SIMLIFE® technology. SETTING: Institute of Anatomy and Surgical Simulation, Toulouse University Hospital. METHODS: Twenty unilateral levels I to IV neck dissections were performed on 11 body donors using a perfused SIMLIFE® model with isolated cephalic perfusion. Seven experts and 5 residents participated. Face and content validity were assessed using Likert-scale questionnaires, whereas construct validity was evaluated using the Onco-Neck-Score through blinded video assessment. RESULTS: High face validity was demonstrated across most assessed domains, particularly venous wall consistency, venous coloration, nerve appearance, and bleeding flow following vascular injury. Experts rated the model as highly relevant for resident training and surgical skills acquisition. Construct validity was supported by significantly higher Onco-Neck-Score values among experts compared with residents (70.8 [interquartile range 68.8-71.0] vs 58.2 [interquartile range 53.8-61.9], P < .001). CONCLUSION: This study supports the face, content, and construct validity of a cadaveric model using isolated cephalic perfusion for cervicofacial surgical training. It provides a realistic environment for neck dissection simulation and may represent a promising tool for surgical education and competency assessment.
