[Neurotrophic ulcer as late sequela of trigeminal nerve excision].

A patient is presented with trophic ulcerations in the area innervated by the trigeminal nerve occurring 17 years after alcohol injection into the trigeminal ganglion and 16 years after excision of the trigeminal nerve. The mean period from time of trigeminal nerve injury to onset of the ulcer usually varies from several weeks to 1 or 2 years as reported in the literature. Our case demonstrates a late manifestation of the trigeminal trophic syndrome.
