Summary: Objective: Preoperative training of surgery is extremely diverse including practice of the
microsurgical technique, learning of anatomy, and surgical video observation. The knowledge regarding
these is generally evaluated in the board certification test of neurosurgery; however, there are few
reports on the objective evaluation of the surgical techniques. In this study, we reported on our evaluation method of the surgical technique.
Materials: We are conducting a technical examination in the form of a contest for the doctors who
have been working for 10 years or less by the following method. Till date, more than 50 neurosurgeons
have been enrolled, with consistent results, which will be reported.
Method: The total allotted time is 5 min. After the arteriotomy of the 1-mm artificial vessels, suturing
is performed with a 10 - 0 suture. We present the basic tasks beforehand through the video. Evaluation
items are graded by four stroke surgical supervisors. Evaluation items are the technique of using microscope, tremor of the hand, and ligature suturing technique. The contents of the examination are
determined considering reproducibility, cost, objectivity of evaluation, and continuity.
Results: In order to prevent differences in rating by graders, but there was no significant difference in
rating by the evaluator.
Conclusion: By objectively evaluating the same surgical technique, it is possible to perform relative
evaluation of the individual technique, perform objective evaluation of the individual technological
growth, and determine the pros and cons of individual technologies.
