A Rare Cause for Recurrent Implant-Related Inflammation of Orbit: Dacryocystitis.

Ultra-thin porous polyethylene has been widely preferred in orbital blow out fracture repair for many years as a safe and stable material. Delayed complications related to the implant in orbital blow out fracture repair are very rare and usually begin as a periorbital inflammation. Infections and tissue reaction to the foreign body are regarded as main causes for implant-related inflammation of which symptoms may vary among the patients and may involve subacute and chronic eyelid swelling, skin redness, pain, conjunctival injection, proptosis, and acute orbital inflammation.Presented here is a patient of recurrent periorbital inflammation who underwent orbital floor repair with ultra-thin porous polyethylene sheet which was complicated by dacryocystitis in the late follow-up period.
