Abstract
BACKGROUND: Supermicrosurgery is an increasingly important technique in reconstructive surgery. It requires a more technically refined skill set compared with standard microsurgery. All currently available biologic training models involve the use of live rats. A nonliving model would be more accessible and cost-effective for practice. We have developed such a model using chicken thighs purchased from a local grocery store. METHODS: The ischiatic neurovascular bundle was identified in 20 chicken thighs and dissected distally to the end of the specimen. The vessel diameters were measured at several points along the artery, vein, and their respective branches. Vessels with diameters in the 0.3-0.8-mm range were then divided and supermicrosurgical anastomoses were attempted. RESULTS: The branching pattern of the ischiatic artery and vein were anatomically consistent with intermediate and terminal secondary and tertiary branches consistently in the range of 0.3-0.8 mm. In all specimens, at least one 0.3-mm vessel could be identified, though additional intramuscular dissection was sometimes required. It was demonstrated that supermicrosurgical anastomoses could be successfully performed using these branches. CONCLUSIONS: This study introduces a novel, convenient, and economical model for supermicrosurgery utilizing easily obtained chicken thighs. The chicken thighs have an anatomically consistent vascular branching pattern, and vessels of appropriate sizes for training can be easily identified and isolated. Surgeons looking to develop or refine supermicrosurgical skills may find this nonliving, biologic model very useful. Published by Elsevier Ltd.
