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 On basis of clinical observation paediatricians in Kinshasa had the impression that children with homozygous sickle cell disease have a special face characterised by hypertelorism. OBJECTIVE The purpose of the study is to determine outer orbital, inner canthal and interpupillary distances as well as proptosis in children with sickle cell disease. METHODS These measurements were p...

The number of well-documented true giant cell tumours arising in any of the craniofacial bones is small, but they do exist. A 19 year old female, Ms. KS, presented with complain of progressive enlargement of facial bones especially jaw bones, then orbit symmetrically since the age of 7. There was bilateral gross enlargement of mandible, maxilla, orbital walls, causing displacement of eye medial...

After orbital exenteration for neoplasia the remaining bony socket is usually lined with skin and the deformity covered with a prosthesis; in many cases this is acceptable to the patient. However, in certain circumstances, especially in younger patients, a request for some form of reconstruction is made. In the past this has involved multistaged local or distant flaps, lined by skin grafts (Mey...

Reconstruction materials and techniques for the base of the skull have undergone rapid developments and differentiation in recent years. While mostly autotransplants, collagens or resorbable alloplastic materials are preferred for duraplasties, pronounced organ-specific differences can be observed in the reconstruction of hard tissues. The use of polymethylmethacryl bone cement, once wide-sprea...

BACKGROUND Primary nasal natural killer (NK)/T-cell lymphoma is the most common cellular subtype seen in nasal lymphomas. It is rare in the Western population but occurs more frequently in Asia, South America, and Mexico. The purpose of this study was to describe the computed tomography (CT) and magnetic resonance (MR) imaging findings of primary nasal NK/T-cell lymphoma. METHODS During the p...

AIM To investigate optic nerve function using the pattern-reversed visual evoked cortical potentials (VECP) before and after bony orbital decompression in dysthyroid optic neuropathy (DON) due to Graves' disease. METHODS A total of 30 eyes of 15 patients (n=14 female) were observed over 30 ± 13 months after bony three-wall orbital decompression. We examined visual acuity (VA), VECP P100 ampli...

PURPOSE Malignant sinonasal tumors are clinically challenging due to their proximity to vital structures and their diverse histogenesis and biological behavior. To date, no animal models accurately reflect the clinical behavior of these malignancies. We developed an orthotopic murine model of sinonasal malignancy that reproduces the intracranial extension, bony destruction, and spread along neu...

Prostate cancer is mostly known to metastasize to the bony skeleton. Soft tissue metastasis involving visceral organs such as the liver, lung and brain are unusual and rare manifestations of this cancer. However, with better treatment modalities and increased survival, the incidence of these unusual presentations, seems to have risen in the last few years. Prostate cancer is rarely known to met...
