Summary
Posterior auricular muscle complex grafts are effective for wrapping hydroxyapatite orbital implants in enucleation surgery. This technique offers satisfactory cosmetic and functional outcomes with minimal complications for patients requiring primary or secondary orbital implants.
Area of Science:
- Ophthalmology
- Plastic and Reconstructive Surgery
Background:
- Hydroxyapatite orbital implants are commonly used after enucleation.
- Covering these implants is crucial for successful outcomes and patient satisfaction.
Purpose of the Study:
- To evaluate the efficacy of posterior auricular muscle complex grafts as a wrapping material for hydroxyapatite orbital implants.
- To assess the safety and cosmetic results of this surgical technique.
Main Methods:
- A retrospective multicenter study involving 83 patients undergoing enucleation surgery.
- Autogenous posterior auricular muscle complex grafts were used to cover hydroxyapatite orbital implants.
- Mean follow-up was 36 months.
Main Results:
- Only 2.4% of patients experienced limited orbital implant exposure, successfully managed with secondary grafts.
- No cases of postoperative infection, implant extrusion, or donor site complications were reported.
- All patients achieved satisfactory cosmetic and functional results with prosthesis fitting.
Conclusions:
- Autogenous posterior auricular muscle complex grafts are a safe and effective option for wrapping hydroxyapatite orbital implants.
- This technique is suitable for both primary and secondary enucleation cases.
- The procedure yields excellent aesthetic and functional results with a low complication rate.
