Summary
Bovine pericardium offers a viable alternative to sclera for wrapping porous orbital implants after enucleation, showing a low complication rate. This method demonstrates favorable outcomes for orbital implant procedures.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Surgical Innovation
Background:
- Porous orbital implants are used after enucleation to maintain orbital volume and support ocular prosthesis.
- Traditional wrapping materials like sclera have associated complication rates.
- Exploring alternative biocompatible materials is crucial for improving patient outcomes.
Purpose of the Study:
- To evaluate the efficacy and safety of using bovine pericardium as a wrapping material for porous orbital implants.
- To compare the complication rates of bovine pericardium-wrapped implants with existing literature.
Main Methods:
- Retrospective review of 80 patients who received bovine pericardium-wrapped orbital implants between 1996 and 1999.
- Data collection included patient demographics, follow-up intervals, and intraoperative/postoperative complications.
- Analysis focused on implant exposure, infection, rejection, and vascularization.
Main Results:
- No intraoperative complications or signs of systemic infection/rejection were observed.
- Four out of 80 patients (5%) experienced complications requiring implant removal, primarily implant exposure.
- Vascularization appeared normal, with no issues noted after secondary drilling for coupling posts.
Conclusions:
- Bovine pericardium wrapping for porous orbital implants resulted in a low incidence of implant exposure (<4%).
- This rate is favorable compared to reported rates for scleral wrapping (9-21%).
- Bovine pericardium is a safe and effective alternative material for wrapping orbital implants.
