Summary
The Thiel cadaver model effectively simulates peripheral nerve repair. The Micro-Neurorrhaphy Evaluation Scale (MNES) is a reliable tool for assessing surgical skills in this simulation setting.
Area of Science:
- Surgical Education
- Microsurgery Simulation
Background:
- Surgical training is shifting to a competency-based model, increasing the need for high-fidelity simulation.
- The Thiel cadaver model offers a realistic platform for surgical simulations, including microvascular procedures.
Purpose of the Study:
- To evaluate the Thiel cadaver model for peripheral nerve simulation.
- To validate a novel assessment tool, the Micro-Neurorrhaphy Evaluation Scale (MNES), for nerve coaptation procedures.
Main Methods:
- Sixteen residents performed nerve coaptations on Thiel cadaveric nerves.
- Evaluations were conducted by 5 fellowship-trained microsurgeons using the MNES.
- Video recordings of the procedures were analyzed.
Main Results:
- The MNES demonstrated excellent interrater reliability (ICC=0.75) and internal consistency (Cronbach α=0.77).
- A significant positive correlation was found between MNES scores and resident experience levels.
- The Thiel nerve tissue proved suitable for peripheral nerve surgical simulation.
Conclusions:
- The Micro-Neurorrhaphy Evaluation Scale (MNES) is a validated instrument for assessing peripheral nerve repair skills.
- The Thiel cadaver model is a valuable tool for high-fidelity peripheral nerve surgical simulation and training.
