Chimeric Versus Multiple Simultaneous Free Flaps for Head and Neck Reconstruction.

The complexity of large head and neck defects poses a reconstructive challenge for microvascular surgeons. Our findings suggest that chimeric and multiple flaps both produce acceptable complication rates when used appropriately. Differences in complication rates may reflect differences in utilization. The chimeric flap remains a valuable option for those with prior radiation or radical resection, but it remains unclear the degree to which they lessen the inherent risk of postoperative complications within this population. Each technique must be weighed in context of the patient's reconstructive profile and the institution's surgical capabilities to optimize long-term outcomes.
