Can a damaged hypoglossal nerve be repaired?
Repair of Hypoglossal Nerve Injury Similar to facial nerve repairs, the ideal management involves establishment of a tension-free anastomosis (Avitia & Osborne, 2008). Although this is preferably performed with end-to-end anastomosis if possible, the use of interposition grafts can be used.
What would happens if the abducens nerve is damaged?
