Summary
A novel orange model provides an accessible and affordable method for neurosurgery residents to practice essential microsurgical skills. This training tool improves hand-eye coordination and task efficiency, validated through measurable outcomes.
Area of Science:
- Neurosurgery Training
- Microsurgical Skills Development
- Medical Education Technology
Background:
- Acquiring basic microsurgical skills in neurosurgery is a global challenge.
- Existing training models are often inaccessible, costly, or time-consuming.
- A readily available, inexpensive model is needed for resident training.
Purpose of the Study:
- To introduce a low-cost, easily set-up training model for basic neurosurgical microsurgical skills.
- To develop and validate measurable tasks using this model.
- To assess the model's utility in improving resident proficiency.
Main Methods:
- Utilized an orange as a training model for dissecting segments while preserving adjacent ones.
- Assessed skill acquisition based on the number of side tears and task completion time.
- Validated the model through repeated trials (n=10) by three operators of varying seniority.
Main Results:
- Significant reduction in side tears (12.66 to 4.35, P < 0.01) and task completion time (28:16 to 16:33, P < 0.01) observed over trials.
- Consistent improvement in daily practice scores and time.
- Operator seniority correlated with performance scores.
Conclusions:
- The orange model offers a practical, cost-effective solution for learning basic microneurosurgical skills.
- Validated, reproducible tasks allow for objective tracking of skill progression and experience.
- This model can be integrated into resident training for foundational microsurgical competency.
