SummaryMicrosurgery is an essential technique in free flap reconstructions today. The technical skills involved require a learning curve, which may be affected by the current issues of limited training resources and patient safety. We describe a study on the value of a microsurgery training device as an assessment and warm up tool in basic microsurgery skills.Forty volunteers with different levels of microsurgery experience performed a microsurgical ‘round-the-clock’ exercise on the training device three consecutive times. Video-recordings of these performances were rated by two blinded independent assessors using a modified Global Rating Scale to assess basic microsurgery skills on the following parameters: steadiness, instruments handling and speed. Time to complete a round was also recorded objectively. The Kruskal–Wallis test was used to analyse the construct validity of the parameters assessed between the groups of level of microsurgery experience. Crohnbach's coefficient α was used to determine the reliability index of the independent assessors.All participants improved their time on consecutive rounds of the exercise. A median of 82 s (range 6–583 s) improvement in time between the first and third round was observed. Different mean performance time could be identified between the groups, but individual speed did not correlate significantly with microsurgery experience. Assessment of microsurgery skills using the modified Global Rating Scale demonstrated statistically significant differences for instruments handling (p = 0.03) and speed (p = 0.01) between the groups with regard to microsurgery experience, and improvement in the parameters assessed for all groups. Difference in steadiness (p = 0.07) was not significant amongst the juniors.Consultants performed better than juniors but, at all levels of experience, significant improvement in skills was demonstrated after practice. The ‘round-the-clock’ microsurgery training device is an inexpensive and readily available valid tool that provides a useful warm up exercise and instant assessment of basic microsurgical skills.
