Trigeminal Trophic Syndrome Leading to Orbital Cellulitis.

ABSTRACT

Trigeminal trophic syndrome is a rare condition that develops from trigeminal nerve damage causing dysesthesias that result in self-mutilation. Facial and nasal destruction develops from self-destructive behavior (repetitive picking or scratching) secondary to the altered skin sensation created by the damaged trigeminal nerve. Early recognition of this condition is crucial to the prevention of the detrimental complications of facial ulceration and nasal tissue necrosis that can lead to corneal ulcerations, full-thickness eyelid defect, and canthal lesions. This case demonstrates a previously unreported complication orbital cellulitis.
