Answer

Synkinesis is expected for all cases of facial nerve transection, regardless of the mode of repair chosen, and the best result one can hope for is a House-Brackman grade III. These consequences therefore should be viewed not as complications but as expected sequelae.

Donor-site morbidity is also expected for the hypoglossal crossover technique (tongue weakness), great auricular harvesting (ear numbness), and sural nerve harvesting (lateral leg numbness). Complications for each of the procedures include hematoma and infection.
