Perspective on Orbital Enucleation Implants

Survey of Ophthalmology, 2007
The philosophy and design of orbital enucleation implants have evolved significantly over the past 50 years. Animal studies and improved imaging techniques have changed our understanding about the physiology and anatomy of the post-enucleation orbit. Changes in implant design and biomaterials have reduced complication rates.

Orbital implants

Current Opinion in Ophthalmology, 1996
Several aspects of orbital implants are reviewed. Hydroxyapatite has become one of the most commonly used implants for anophthalmic patients and has many of the characteristics desirable in an implant, although reports of significant complication rates are noted.

Orbital implants: material matters

British Journal of Ophthalmology, 2021
In ‘Case series of shrinking hydroxyapatite orbital implants’, Han et al 1 draws attention to a particularly interesting postoperative complication. The authors report the potential shrinking of mammalian bone-derived hydroxyapatite orbital implants by osteoclastic activity, which may lead to orbital volume loss.

The Bioceramic Orbital Implant

Ophthalmic Plastic & Reconstructive Surgery, 2003
To assess the problems associated with the Bioceramic (Aluminum oxide, Al(2)O(3)) orbital implant.A consecutive case series of 107 patients receiving a Bioceramic orbital implant by two surgeons over a 3-year period were reviewed. The authors analyzed patient age, type of surgery, size of implant, peg system, follow-up duration, time of pegging ...

Integrated orbital Implants

Ophthalmic Plastic & Reconstructive Surgery, 1990
Newer trends in enucleation surgery have included placement of the orbital implant deep within the muscle cone. The use of homologous or autologous tissue to wrap the implant has aided in decreasing extrusion. Newer implant materials show promise in reducing extrusion and in creating an integrated motility implant.

Resorbable Implant for Orbital Defects

American Journal of Ophthalmology, 1982
Tricalcium phosphate ceramic, a synthetic bone substitute, was inserted into defects created in the inferior orbital rims of 18 rabbits. The animals were killed after three, eight, 24, and 40 weeks. Early sections demonstrated encapsulation with fibrous ingrowth.

Orbital Floor Implants

Archives of Otolaryngology - Head and Neck Surgery, 1969
THE ORBITAL floor may be involved in various types of facial fractures; in particular, the tripod fracture of the zygoma, the blowout fracture, and fractures of the maxilla of the LeFort II and III types. Surgical repair may be necessary when the orbital floor is so comminuted as to permit entrapment of the ocular muscles, or a defect is present which
