|November 1, 1983
Summary
Autogenous dermis-fat orbital implants effectively restore orbital volume and preserve ocular structures. While generally safe, secondary implantations, especially in chemically injured sockets, show a higher risk of graft atrophy.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Reconstructive Surgery
Background:
- Orbital implants are crucial for maintaining orbital volume after enucleation.
- Autogenous dermis-fat grafts offer a reconstructive option for various orbital defects.
Purpose of the Study:
- To evaluate the efficacy and outcomes of dermis-fat orbital implants.
- To assess graft survival rates in primary versus secondary implantations.
Main Methods:
- Retrospective review of 118 dermis-fat orbital implant procedures over six years.
- Categorization of implants into primary, secondary (migrated implant removal), and corrective (superior sulcus deformity, contracted socket expansion).
Main Results:
- Dermis-fat grafts effectively maintained orbital volume, preserved fornices, and conserved conjunctiva.
- Graft atrophy was infrequent in primary implantations (1 of 51 cases).
- Higher atrophy rates (3 of 9 cases) were observed in secondary implantations, particularly in chemically injured, contracted sockets.
Conclusions:
- Autogenous dermis-fat orbital implants are effective for restoring orbital volume and function.
- Graft survival is generally high, but secondary procedures in compromised sockets warrant careful consideration due to increased atrophy risk.
