Zygomatic implants have been used for rehabilitation of the edentulous atrophic maxilla as an alternative to bone grafting for almost two decades resulting in satisfactory clinical outcomes. However, the patients with edentulous atrophic maxilla treated using this technique may present serious complications that could put the prosthetic restoration at risk. Four cases are reported in this paper...

purpose : to report a patient with orbital pseudotumor masquerading as orbital cellulitis case report : a 42-year-old woman was referred to orbit and oculoplastic clinic with 6 days history of left orbital pain, proptosis, lid edema and fever. clinical finding included severe lid edema, chemosis, conjunctival injection and severe restriction in extraocular motility. she was diagnosed as orbital...

PURPOSE To investigate both feasibility and clinical potential of magnetic resonance imaging-dynamic color mapping (MRI-DCM) in measuring the motion of soft tissues in the orbit and in the diagnosis of orbital disorders by detecting changes in motion. METHODS Sequences of MRI scans were acquired (acquisition time, 5 seconds) in a shoot-stop manner, while the patient fixated at a sequence of 1...

BACKGROUND Many implants are being used for the reconstruction of orbital wall fractures. The effect of the choice of implant for the reconstruction of an orbital wall fracture on the surgical outcome is under debate. The purpose of this article is to compare the outcomes of orbital wall reconstruction of small orbital wall fractures on the basis of the implants used. METHODS The authors cond...

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...

BACKGROUND Restoring the orbital cavity in large blow out fractures is a challenge for surgeons due to the anatomical complexity. This study evaluated the clinical outcomes and orbital volume after orbital wall fracture repair using a rapid prototyping (RP) technique and intraoperative navigation system. METHODS This prospective study was conducted on the medical records and radiology records...

While the primary goal of reconstruction following orbital exenteration is lining or filling of the defect to protect the cranial contents, orbital exenteration without full rehabilitative efforts is debilitating to patients due to the resulting psychosocial disability [4,5]. Therefore, many patients strongly desire to obtain a prosthetic [2,3]. Typically, open cavity reconstruction of the orbi...

OBJECTIVE To determine the orbital tolerance of a microporous implant fitted with an integrated stainless steel post and the enhanced motility associated with magnetic coupling of the prosthetic and the implant in a rabbit model. METHODS Six New Zealand white rabbits underwent primary enucleation with implantation of a 12-mm microporous polyethylene implant with a 2 x 3-mm stainless steel pos...

BACKGROUND The term "orbital blow-out fracture" is referred to as the mechanism by which an impact to the eyeball is transposed as a mechanical energy to the orbital walls, causing them to fracture. Despite a proper surgical technique, a successful anatomic reconstruction of the orbit, and an accurate follow-up, 3 complications are still frequently observed at long-term follow-up: diplopia, eno...

INTRODUCTION This article reports experience relating to the measurement of orbital volume by means of cone beam computed tomography (CBCT) and Cranioviewer program software in patients who have undergone enucleation and orbital implantation. PATIENTS AND METHODS CBCT scans were made in 30 cases, 10 of which were later excluded because of various technical problems. The study group therefore ...
