Aims: To document the long term experience of bone derived hydroxyapatite orbital implants and compare results using scleral wrapped implants with those not using sclera. Methods: This retrospective case series reviewed the long term follow up of 118 patients with 120 eyes which had undergone enucleation and bone derived hydroxyapatite orbital implant insertion at Dunedin Hospital from 1977 unt...

AIMS To document the long term experience of bone derived hydroxyapatite orbital implants and compare results using scleral wrapped implants with those not using sclera.

THIs implant was developed with the object ofincreasing the degree ofmovement obtained with the Allen type ofburied orbital implant. The satisfactory way in which these implants are retained in the orbit is demonstrated by the large number which have now more than fulfilled the 2-year follow-up period suggested by Choyce (1952). The retention of the magnetic form of implant appears to be as goo...

BACKGROUND Porous polyethylene implants are commonly used in orbital blowout fracture repair because of purported biocompatibility, durability, and low frequency of complications. Delayed inflammation related to porous polyethylene sheet implants is very rare and no case series of this condition have been reported. CASE PRESENTATION This is a retrospective review of clinical presentations, ra...

PURPOSE To evaluate the safety and efficacy of the porous polyethylene multipurpose conical orbital implant for use in evisceration. METHODS A retrospective review of 31 eyes that underwent evisceration and received the multipurpose conical orbital implant. The orbits were evaluated at 1 week, 1 month, and 6 months after final prosthetic fitting for implant exposure, superior sulcus deformity...

Alloplastic materials used for orbital fracture reconstruction can induce complications, such as infection, migration, extrusion, intraorbital hemorrhage, and residual diplopia. Silicone is one of the alloplastic materials that has been widely used for decades. The author reports a rare case of spontaneous extrusion of a silicone implant that was used for orbital fracture reconstruction 30 year...

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 ...

PURPOSE To describe the use of computer-based orbital volume measurement as a predictor of late enophthalmos, and to assess the effectiveness of the MedPor (Porex Surgical Products Group, Newnan, GA) porous polyethylene channel implant to restore orbital volume in repairing large orbital wall fractures. METHODS Sixteen patients with unilateral large orbital fractures were included. Computed t...

PURPOSE The purpose of this study was to obtain anatomical information for installing four zygomatic implants, by measurements of maxillae and zygomata. MATERIALS AND METHODS Linear and angular measurements were obtained from the maxillae and zygomata of 40 dry skulls. RESULTS Based on mean and standard deviation values, the installation angle of the additional implant in the four zygoma te...
