When there is too large of a gap for repair or a large quantity of tissue has to be removed from the nerve endings, nerve grafting takes a non-essential nerve from a separate location on the body and used to bridge the nerve gap. Nerve graft substitutes derived from donated nerve tissues are also appropriate for some patients.
Periodic exams after nerve repair are required to chart the progress of the regenerating nerve fibers. Signs of recovery include returning muscle tone and contraction and restore voluntary movement. The advancing nerve fibers within the recovering nerve will tingle when tapped.
