Resumen

Zirconia-alumina ceramic foam scaffolds with a nanocrystalline HAP coating were used for the preparation of integrated motile orbital implants. This study demonstrated that open-cell ceramic foams with enhanced strength-to-density ratio are quite suitable as biocompatible materials for the manufacture of orbital implants for post-enucleation syndrome treatment. In-vivo studies demonstrated that the application of a nanocrystallyne (not sintered) HAP coating facilitated the formation of dense fibrous capsule around the implant as well as the fast tissue ingrowth into the implant’s internal spac

Resumen

AbstractOrbital and craniomaxillofacial defects, in general, are best approached preoperatively by a multidisciplinary team with a clear reconstructive plan in place. Orbital defects result from a myriad of underlying diseases and injuries, and reconstruction after orbital evisceration, enucleation, or exenteration can pose a challenge to the reconstructive team. Reconstruction of orbital injuries with orbital implants and prostheses can lead to acceptable aesthetic outcomes, and the reconstructive surgeon should be familiar with current orbital implants and prostheses.

Resumen

Orbital implant, used for filling the space after enucleation, played an important role in the optical orthopedic operations. However, the clinical application of soft orbital implants was in a limited extent. This paper focused on the synthetic method of a new kind of soft poly (2-hydroxyethyl methacrylate) (PHEMA) orbital implant. This method included two steps, making the orbital implant with through-holes by salt leaking method and improving the compress property of PHEMA by copolymerizing it with methyl methacrylate (MMA).

Resumen

Enucleation consists of surgical removal of the entire eye globe with preservation of the conjunctiva, extraocular muscles, orbital fat, and optic nerve. This surgical procedure is generally accepted treatment for intraocular malignancies, blind painful eye, severely traumatized eye, phthisis bulbi, and to improve cosmetic appearance. Once the eye is removed, orbital volume enhancement typically requires implantation of spherical materials that can be classified into two major groups: non-porous and porous orbital implants. Different surgical techniques have been described in the literature, i

Resumen

Pure orbital blowout fractures occur within the confines of the internal orbital wall. Restoration of orbital form and volume is paramount to prevent functional and esthetic impairment. The anatomical peculiarity of the orbit has encouraged surgeons to develop implants with customized features to restore its architecture. This has resulted in worldwide clinical demand for patient-specific implants (PSIs) designed to fit precisely in the patient’s unique anatomy.

Resumen

There is a lack of consensus regarding preferred implant materials for orbital floor fracture reconstruction, leading to surgeon- and institution-dependent preferences. A variety of implants are used for orbital floor fracture reconstruction, each with their own complication profile. Knowledge of different implant materials is critical to identifying complications when they present. We report a delayed periorbital abscess 5 years after orbital floor reconstruction using a silicone implant.

Resumen

Titanium implants in facial bones for retention of epitheses or dental bridges were used for reconstruction in cancer patients after tumor surgery. Even heavily irradiated bones could integrate the implants and bear the load from the epithesis. No major complications, such as wound infection, fistulation, or osteoradionecrosis, occurred after implant surgery. There was, however, an increased loss of implants with time after irradiation, especially in the orbital region. When hyperbaric oxygen was used as adjunctive treatment, implant losses were reduced.

ABSTRACT Neoplasms, congenital disorders, fungal infections, and traumatic injuries are the predominant causes of orbital defects. Various retentive mechanisms such as application of adhesive, utilization of mechanical undercuts, and implant-supported attachments are generally used in the maxillofacial prosthesis. In the orbital region, the result of magnet-retained attachments is favorable compared with other mechanisms. Different advantages of the magnet-retained prosthesis are less manual dexterity needed during insertion or removal and better maintenance of hygiene. The skin–implant interf

Resumen

Purpose Extrinsic trauma to the orbit may cause a blowout or orbital fracture, which often requires surgery for reconstruction of the orbit and repositioning of the eyeball with an implant. Post-operative complications, however, are high with the most frequent cause of complications being a mismatch of the position and shape of the implant and fracture. These mismatches may be reduced by computed tomography (CT) based modeling and three-dimensional (3D) printed guide. Therefore, the aim of this study is to propose and evaluate a patient-specific guide to shape an orbital implant using 3D print

Resumen

The purpose of reconstruction of an orbital fracture is restoration of normal structure and volume without visible or functional complications. In a previous study, orbital implants were created using three-dimensional (3D) printing technology to restore orbital fractures. In the present study, the authors compared the efficacy of the conventional manual-bending implant and the 3D-printed standardized implant in order to verify the clinical utility of the fabricated 3D printed orbital implant. In this single-center, retrospective study, the authors evaluated medical records and 3D-CT scans of

Resumen

Purpose: There are no universally established guidelines for material selection in orbital wall fracture reconstruction. With an increasing preference for permanent implants, this study aimed to compare the long-term clinical outcomes of three different non-resorbable materials in reconstructing isolated orbital floor fractures. Design: A retrospective, interventional comparative study. Methods: The medical records of patients with unilateral pure orbital floor fractures who underwent orbital reconstruction using non-resorbable alloplastic implants at two tertiary referral centers between Janu

Resumen

Objective: Options for the management of orbital floor fractures continue to evolve offering both potential advantages as well as higher costs. To date, the effect of implant choice on the cost associated with the repair of orbital floor fractures has not been studied. Methods: A retrospective review at a tertiary care, level I trauma center examining all adult, uncomplicated orbital floor fractures that underwent open reduction and internal fixation from 2013 to 2016. Patients with concurrent operative facial fractures were excluded. The main outcomes were overall cost of care from injury to

Resumen

ABSTRACT Orbital implants replace the volume lost by enucleated eye, impart motility to the prosthesis, and maintain cosmetic symmetry with the fellow eye. They include nonintegrated, synthetic semi-integrated, integrated, bio-integrated, and biogenic varieties. The much favored hydroxyapatite (bio-integrated) implant, due to its rough surface, needs to be wrapped in donor sclera or other wrapping materials (like polyglactin-910 mesh, polytetrafluoroethylene sheet, etc.) to which the muscles could be directly sutured. Cost factor of such wrappings is often prohibitive that add to the expense o
