Trigeminal Trophic Syndrome

Trigeminal trophic syndrome (TTS) is a rare cause of facial ulceration, consequent to damage to the trigeminal nerve or its central sensory connections. We report a case of TTS in a 48-year-old woman with Bell's palsy following herpes zoster infection. The patient was treated and counseled. There has not been any recurrence for 1 year and the patient is being followed-up. The diagnosis of TTS should be suspected when there is unilateral facial ulceration, especially involving the ala nasi associated with sensory impairment.
