Summary
Hydroxyapatite orbital implants offer excellent prosthesis motility and socket movement in enucleated patients. This study found the implant well-tolerated with few complications in 100 cases.
Area of Science:
- Ophthalmology
- Biomaterials Science
Background:
- Orbital implants are crucial for prosthetic rehabilitation after enucleation.
- Hydroxyapatite (HA) is a bioceramic with potential for orbital implant applications.
Purpose of the Study:
- To evaluate the safety and efficacy of hydroxyapatite orbital implants in patients enucleated for intraocular neoplasms.
- To assess prosthesis motility and patient outcomes following hydroxyapatite implantation.
Main Methods:
- A consecutive series of 100 hydroxyapatite orbital implants were placed in patients enucleated for intraocular neoplasms.
- Follow-up included assessment of implant-related complications, socket and fornix movement, and prosthesis motility.
Main Results:
- Excellent socket and fornix movement (99%) and cosmetically satisfactory prosthesis motility (96%) were observed.
- No cases of orbital infection, implant extrusion, or migration occurred.
- Minor complications included transient pain, edema, tissue overgrowth, and peg-related issues.
Conclusions:
- Hydroxyapatite orbital implants are well-tolerated and safe for patients requiring prosthetic rehabilitation after enucleation.
- The implant provides significant prosthesis motility, enhancing cosmetic outcomes with a low complication rate.
