Reinnervation with Selective Nerve Grafting from Multiple Donor Nerves

Nerve substitution is an important tool in facial reanimation. The goal is to reinnervate the distal facial nerve and musculature using an alternative cranial nerve in order to achieve facial movement, symmetry, and tone. Multiple donor nerves have been used for nerve transfer procedures, the most common being hypoglossal, masseteric, and cross-facial nerve graft. Each donor nerve has its advantages and disadvantages. Multiinnervation uses the use of multiple donor nerves in order to leverage the benefits while balancing the pitfalls of each nerve. The nerve transfer depends on the type of nerve injury, time since injury, and patient factors.
