PURPOSE To evaluate through clinical and tomographic parameters implant behavior in orbital zygomatic reconstruction in six patients. METHODS The subjects for this preliminary study consisted of six anophthalmic socket patients (3 patients presented residual orbital zygomatic deformities after complex facial fractures and 3 patients presented orbital zygomatic retraction after enucleation and...

The placement of a motility coupling post (MCP) to integrate the prosthesis with a porous orbital implant may enhance prosthetic motility following enucleation. Previously, MCP placement has required a second operation usually at least 6 months following enucleation. We developed a technique to place an MCP reliably and safely into a porous orbital implant at the time of enucleation. Eligibilit...

PURPOSE To assess orbital volume in weaned rabbits, submitted to enucleation and evisceration, with orbital volume reconstitution using porous polyethylene (PP) spheres, analyzed by computed tomography, by the water displacement test and external orbital measures using Image-J software. METHODS This experimental randomized study consisted of 48 albino rabbits, with 42 days of life, submitted ...

DESCRIPTION Ten days after reconstruction of an orbital floor blow out fracture with a porous polyethylene implant, a 23-year-old man presented with sudden onset of swelling and proptosis of the right eye following weightlifting.

THIS is a preliminary report of a new magnetic ocular obturator for use after enucleation of the globe. It is a completely buried implant. An attempt has been made to bring the research, design, construction, and surgery of the new instrument into continuity with previous models of the post-eviscerative type, some partially buried and some wholly buried within the orbital structure, applying th...

A glaucoma drainage implant was detected on plain skull radiographs before MR imaging examination of the brain. The patient was denied the MR imaging for fear of dislodging the "metallic foreign body." The Baerveldt glaucoma drainage implant was mistakenly identified as an orbital metallic object based on its radiographic characteristics. Because none of the current glaucoma drainage implants c...

This report details a technique for spheno-orbital reconstruction after meningioma resection. The approach uses a life-size skull model generated from a thin-slice craniomaxillofacial computed tomogram. On this skull model, the planned area of bone removal of the involved orbit and sphenoid is outlined on the normal side opposite the lesion. A three-dimensional implant is then generated by reve...
