Effectiveness of suturing training with 10-0 nylon under fixed and maximum magnification (×20) using desk type microscope

BackgroundMicrovascular anastomosis using 10-0 nylon needs a higher level of technical dexterity compared with routine neurosurgical maneuvers. Although this technique remains an important part of treating complex intracranial aneurysms or cerebrovascular disease, the surgeon's clinical experience in using this technique is not so common.MethodsTo improve dexterity and maneuverability in the limited clinical case volume, we developed an easily accessible training system, using commercially available desk type microscope and simply suturing neighboring fibers of the gauze with 10-0 nylon under fixed and highest (×20) magnification.ResultThis training system is somewhat of a drawback compared to the simulation of a real clinical setting. However, because of the extremely easy availability and accessibility of the dark type microscope repeated training and the accumulation of more than 10 000 stitches, on average, was accomplished. This resulted in a steep learning curve of the technique.ConclusionFor residency and post-residency year young neurosurgeons, who need to brush up their skills due to lower surgical case volume compared with what senior neurosurgeons have experienced this easily available training would contribute to establishing daily and long-lasting microsurgical practice.
