Sixty-six consecutive cases undergoing enucleation with the insertion of the Roper-Hall magnetic implant at the Birmingham and Midland Eye Hospital (BMEH) were followed up to re-establish the rate of extrusion. It was possible to study the records of all 66 patients. An extrusion rate of 1.5% was found.

External impact to the orbit may cause a blowout or zygomatico-maxillary fractures. Diagnosis and treatment of orbital wall fractures are based on both physical examination and computed tomography scan of the orbit. Injuries of the orbit often require a reconstruction of its orbital walls. Using computer-assisted techniques, anatomically preformed orbital implants, and intraoperative imaging of...

OBJECTIVE The most accurate orbital reconstructions result from an anatomic repair of the premorbid orbital architecture. Many different techniques and materials have been used; unfortunately, there is currently no optimal method. This study compares the use of preformed vs intraoperative bending of titanium mesh for orbital reconstruction in 2-wall orbital fractures. STUDY DESIGN Cadaver-bas...

rehabilitation of facial defects is a complex task, requiring an individualized design of the technique for each patient. the disfigurement associated with the loss of an eye may result in significant physical and emotional problems. various treatment modalities are available, one of which is the use of implants. although implant-supported orbital prosthesis has a superior outcome, it may not b...

BACKGROUND In addition to functional goals, a satisfactory aesthetic outcome is important for reconstruction of fronto-orbital osseous defects. The purpose of this study is to report on a method for presurgical fabrication of custom implants using 3-dimensional (3-D) imaging data and computer-assisted manufacturing techniques. METHODS Preoperative 3-D computed tomography data were processed a...

This retrospective study evaluated the use of percutaneous craniofacial implants for the prosthetic rehabilitation of patients with a history of orbital exenteration and irradiation for oncologic tumors of the head and neck. A total of 24 implants were placed in six patients. All implants were determined to be osseointegrated at the time of uncovering. Three implants were subsequently resubmerg...

Objective. This study aimed to define CBCT as a technique for postimplantation in vivo examination of porous hydroxyapatite and aluminium-oxide orbital implant shape, volume and density changes. Methods and Materials. CBCT was used to evaluate 30 enucleated patients treated with spherical polyglactin 910 wrapped hydroxyapatite and aluminum-oxide orbital implants. The mean duration of patient fo...

Alloplastic implants have been used to repair orbital wall fractures in most cases. Orbital hemorrhage is a rare complication of these implants and has been reported rarely in Korea. The purpose of this article is to report a late complication case focusing on their etiology and management. A 20-year-old male patient underwent open reduction with Medpor (porous polyethylene) insertion for bilat...

PURPOSE To compare artificial eye amplitudes in enucleated socket with porous polyethylene either spherical or quad-motility implant and study the characteristics of artificial eyes fit with the two orbital implants. METHODS A total of 21 patients were prospectively studied who underwent enucleation because of an intraocular melanoma and the randomization defined a porous polyethylene either ...
