Summary
Hydroxy-apatite (HA) spheres effectively restore the anophthalmic socket for both primary and secondary cases. This orbital implant offers excellent motility and cosmetic results with no serious complications.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Reconstructive Surgery
Background:
- Anophthalmic socket reconstruction is crucial for restoring facial aesthetics and function.
- Hydroxy-apatite (HA) has shown promise as a biocompatible material for orbital implants.
Purpose of the Study:
- To evaluate the efficacy and safety of hydroxy-apatite (HA) spheres for primary and secondary anophthalmic socket restoration.
Main Methods:
- 33 patients (19 primary, 14 secondary) received HA spheres (16-20 mm) wrapped in donor sclera.
- Extraocular muscles were attached where possible; buccal membrane grafts were used in 3 cases.
- Surgical technique included scleral wrapping and, in some cases, drilling for implant fixation.
Main Results:
- Follow-up ranged from 7 to 69 months with no major complications, only transient postoperative edema.
- Excellent implant motility was achieved in all patients.
- Primary implantations resulted in acceptable symmetry, while secondary implantations dramatically improved facial appearance.
Conclusions:
- Hydroxy-apatite (HA) spheres are a safe and highly effective orbital implant for both primary and secondary anophthalmic socket reconstruction.
- The use of HA spheres leads to excellent functional and aesthetic outcomes.
- No serious complications were associated with HA sphere implantation.
