Free flap complications: when is enough, enough?

The reconstruction of head and neck defects, be they traumatic, oncologic, or iatrogenic, has been revolutionized in the last two decades by the development and refinement of microvascular soft tissue transfer. What was once an onerous and often unpredictable procedure has become standardized and safe. The result is that free tissue transfer is becoming the standard of care for more and more patients, to the point that the profession must now readdress the role of more traditional techniques of reconstruction. This article reviews the recent literature on free flap-related complications to assess the appropriateness of widespread free flap reconstruction and discusses the changing indications and benefits of free tissue transfer and nonmicrovascular reconstruction.
