Abstract

Seven cases of trigeminal trophic syndrome are reported. In this rare condition, neurotrophic ulcers occur on the face, especially in the ala nasi area in a dermatome of the trigeminal nerve that has been rendered anesthetic, usually as a complication of trigeminal ablation by surgical means or injection for treatment of trigeminal neuralgia. The period from time of trigeminal nerve injury to onset of the ulcer varies from weeks to several years, with a mean of 1 to 2 years. Self-induced trauma is believed to produce the tissue destruction. Once the ulcers appear, they are extremely persistent.
