Painful Posttraumatic Trigeminal Neuropathy (Previous Term: Anesthesia Dolorosa)

A unilateral or bilateral facial or oral pain that follows trauma to the trigeminal nerve(s).[20,103] Pain is accompanied by prominent sensory deficits and other symptoms or clinical signs of trigeminal nerve dysfunction.[1,20]

Pain is usually continuous and burning with occasional spontaneous or touch evoked paroxysms. Together with hallmark allodynia, it should be a straightforward diagnosis, not to be confused with TN.
