The Bioceramic Orbital Implant
Ophthalmic Plastic & Reconstructive Surgery, 2003To 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 ...

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.

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

Resorbable Implant for Orbital Defects
American Journal of Ophthalmology, 1982Tricalcium 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.

Complications of Supramid Orbital Implants
Ophthalmic Plastic & Reconstructive Surgery, 2003To determine the incidence and risk factors of complications associated with Supramid orbital implants.A retrospective chart review was performed to document complications in a series of 41 patients receiving Supramid implants during orbital reconstruction or fracture repair.

A NEW MAGNETIC ORBITAL IMPLANT
Archives of Ophthalmology, 1954INCREASING dissatisfaction with the results obtained after enucleation and the insertion of a glass or plastic sphere implant led to efforts to improve these results by changing the character of the implant and making associated changes in the artificial eye. This work was possible only because our Plastic Artificial Eye and Restorations Clinic had the

MRI of orbital hydroxyapatite implants
Neuroradiology, 1996Our aim was to use MRI for the postsurgical assessment of a new form of integrated orbital implant composed of a porous calcium phosphate hydroxyapatite substrate. We studied ten patients 24-74 years of age who underwent enucleation and implantation of a hydroxyapatite ball; 5-13 months after surgery, each patient was examined by spinecho MRI, with fat

The tolerance of the orbital tissue to foreign materials has always been well known, and for this reason many substances have been implanted in Tenon's capsule. Most ophthalmologists of the present day concede that something should be put into the socket after enucleation in order to obliterate the unnatural folds and depressions in the upper and lower

Postenucleation Orbital Implant Extrusion
Archives of Ophthalmology, 1978A new idea helps to explain postenucleation orbital implant extrusion. Implant extrusion is related to would dehiscence followed by conjunctival epithelial downgrowth. A prospective clinical study with pathological data are used to support this concept. A procedure for repair of this problem is described.

Pegging the Porous Orbital Implant
Ophthalmic Plastic & Reconstructive Surgery, 2011Hydroxyapatite (HA) orbital implants are commonly used for the anophthalmic socket. With a HA implant, if motility is not satisfactory then a peg system can be surgically placed in attempts to improve motility. The authors report the technique and results of 83 patients who received motility peg placement over an 8-year period by a single surgeon ...
