Roger Crumley of the University of California-Irvine, at the Western Section meeting of the Triological Society in Coronado, Calif, reported on the current status of crossface nerve grafting for patients with unilateral seventhnerve palsy. The factors that are clearly identified as positive influences on successful results include youth (less than 50 years of age), a shorter duration of facial paralysis, and the presence of adequate muscle to be reinnervated.
Muscle can be brought in by free-flap transfer or by a temporalis flap. The procedure being performed in two stages offers the advantage of performing a biopsy on the distal nerve ending to be implanted to ascertain presence of axonal activity. The use of nerve growth factor may enhance the success for these procedures.
