Summary
A migrated orbital silastic sheet implant, used for orbital floor fracture repair 20 years prior, caused bilateral sinusitis. Endoscopic sinus surgery successfully removed the implant, highlighting the need for vigilance regarding late orbital implant migration complications.
Area of Science:
- Otolaryngology
- Ophthalmology
- Medical Device Complications
Background:
- Orbital floor fractures often require surgical reconstruction.
- Silastic sheets are utilized for orbital reconstruction.
- Late complications of orbital implants are uncommon but possible.
Observation:
- A patient presented with bilateral sinusitis 20 years after orbital floor fracture repair.
- The sinusitis was caused by a migrated silastic sheet implant.
- The implant had perforated the nasal septum and moved to the contralateral nasal cavity.
Findings:
- Endoscopic sinus surgery confirmed and removed the migrated silastic sheet.
- The implant's migration led to chronic nasal symptoms.
Implications:
- Ocular or nasal symptoms post-orbital fracture repair warrant thorough clinical and radiological evaluation.
- Late migration of orbital implants is a potential complication that should be considered.
- Prompt diagnosis and surgical intervention are crucial for managing implant migration.
