Hypoglossal-facial nerve 'side-to-side' neurorrhaphy for facial paralysis resulting from closed temporal bone fractures

摘要

Background: Closed temporal bone fractures due to cranial trauma often result in facial nerve injury, frequently inducing incomplete facial paralysis. Conventional hypoglossal-facial nerve end-to-end neurorrhaphy may not be suitable for these injuries because sacrifice of the lesioned facial nerve for neurorrhaphy destroys the remnant axons and/or potential spontaneous innervation.
