A second principle of neurolaryngology is that the Xth cranial nerve, when injured, almost always tends to regrow. Mild injuries and injuries close to an individual branch of the nerve will tend to recover with normal function. More severe injuries and we could say more proximal injuries, that is, injuries that are closer to the main trunk of the nerve, will result in regrowth with the crossing of nerve pathways to different branches. This will result in various degrees of mixed up functioning of the nerves and muscles of the larynx. Even in cases where there is a gap between the cut ends of the nerve, the cut neurons will often gradually grow through the intervening tissue and reconnect with the denervated muscles.
