Abstract
Facial paralysis has detrimental consequences on one's ability to function normally and convey emotions. Dynamic facial reanimation is the gold standard treatment in treating the paralyzed face. In combination with motor nerve transfers (hypoglossal, masseteric, etc), contralateral facial nerve branches are able to help provide facial movement and spontaneity by supercharging existing facial nerve branches or by innervating free muscle flaps. Cross facial nerve grafts have proven to be invaluable in allowing the surgeon to creatively optimize the neural network that can supply the weakened face. Many advancements have been made over the years with regards to these grafts, and this article aims to present a brief summary of those findings.
