The cross face nerve graft is a procedure that takes the activity of the normal facial nerve (without compromising) from one side of the face to the other side of the face, typically using a section of nerve taken from the leg to act as a conduit along which nerve fibres can grow from the healthy nerve on the unaffected side. It is important to note that, is used as part of a two-stage reconstruction, this operation does not improve the smile on the affected side of the face, but rather, sets the stage so that the second stage operation can be performed to restore the smile
