Background : It is still controversial whether 3D microscope is an alternative tool for microvascular anastomosis instead of traditional binocular microscope in supermicrosurgery. We compared the usefulness of a 3D microscope (Kestrel View II, Mitaka Kohki Co., Tokyo, Japan) and a binocular microscope (MM51/YOM, Mitaka Kohki Co.) for evaluating microvascular anastomosis of chicken wing training models.
Methods : Three microsurgeons were asked to perform five end-to-end anastomoses on the ulnar artery in a chicken wing using each type of microscope. We evaluated the time and quality of anastomosis, and the students completed a questionnaire about the visibility, ease of anastomosis, tiredness, and general impression after a total of 30 procedures.
Results : The average time required for anastomosis in each microsurgery was 10.3, 12.0, and 12.5 minutes with Kestrel View II, and 8.5, 10.9, and 11.3 minutes with MM51/YOM. The required time tended to be shortened as the number of procedures increased. The anastomotic qualities were almost the same in both microscopes. In the questionnaire, Kestrel View II was scored higher in the ease of surgical operation, but lower in visibility and general impression.
Conclusions : Our study found that a 3D microscope can be used for supermicrosurgical anastomosis.
