Delayed-Onset Orbital Abscess After Orbital Blowout Fracture Repair Using Porous Polyethylene Implant

This study aims at documenting a rare case of delayed-onset orbital abscess following the use of a nonabsorbable porous polyethylene implant in orbital fracture repair, highlighting the potential long-term risks associated with non-biodegradable orbital implants. A 44-year-old man presented with diplopia on down gaze, proptosis, and eyelid edema for 2 weeks. He had undergone repair of an inferior orbital wall fracture with a porous polyethylene implant 5 years ago. Computed tomography (CT) evaluation revealed a significant intraorbital abscess related to implant infection. Surgical interventions included abscess drainage and implant replacement, which led to patient recovery. Nonabsorbable implants, which are beneficial for orbital reconstruction, may pose a risk of occurrence of delayed infections several years following surgery. This report highlights the importance of long-term monitoring to mitigate the risks of potential late complications, which necessitate early diagnosis, appropriate intervention, and management strategies.
