Complex Fistula Formations After Orbital Fracture Repair With Teflon: A Review of 3 Case Reports.

ABSTRACT: The authors present 3 unique cases of complex fistula formations because of orbital fracture repair with a Teflon (polytetrafluroethylene) implant. A 26-year-old man presented with dacryocystitis and a cutaneous fistula 8 years after left orbital floor and medial wall fracture repair with a Teflon implant. A 46-year-old woman suffered orbital trauma after a motor vehicle accident as a teenager and the fracture was repaired with Teflon implant. Thirty-two years later, she presented with lower eyelid fistula, ectropion, and retraction. A 65-year-old woman also previously had Teflon implants for the repair of her left inferior and lateral orbital rim after a motor vehicle accident. Twenty-five years later, she presented with chronic infections involving the repaired areas, as well as left lower lid ectropion and fistula formation. The woven material nature of Teflon acted as a nidus for infection, inflammation, and led to complex cutaneous fistula formations in these patients.
