Free Flap Neurotization: Indications, Techniques, and Future Directions.

[LEARNING OBJECTIVES] After studying this article, the participant should be able to: 1. Understand operative techniques for harvesting several different types of free flaps with sensory innervation. 2. Describe options for donor nerves for common recipient locations. 3. Discuss the clinical outcomes, advantages, and special considerations for free flap neurotization.

[SUMMARY] As techniques have advanced in autologous free tissue transfer, increasing focus has been placed on functional reconstruction that not only achieves soft-tissue coverage but also maximizes overall function. One recent trend is the increasing use of neurotized free flaps to improve the sensibility of free flap reconstruction. Restoration of sensation to a reconstruction not only provides critically protective sensation but can also help to restore a sense of self and incorporation of the reconstructed tissues. In this article, the authors discuss recent trends and techniques in free flap neurotization.
