OBJECTIVE To explore the complications and associated risks factors after orbital exenteration and lateral skull base defect repair. METHODS Patients who had undergone a reconstruction of their orbital cavity and lateral skull base defects were selected from our departmental database. The outcome of interest was postoperative complications. The risks factors were defined as age, sex, history ...

This is a case study of five isolated orbital nerve inflammatory pseudotumor cases presenting with protrusion and visual acuity of the right eye. Optic disk edema was observed by ophthalmoscopy. Plain and contrast-enhanced magnetic resonance imaging (MRI) were used to examine the orbital fat and enlargement of the right optic nerve sheath along with orbital magnetic resonance imaging diagnostic...

OBJECTIVE Hemangiomas are benign vascular lesions mostly arising from soft tissues. However, intraosseous hemangioma is a rare entity, comprising only 1% of benign bone tumors. We describe here the presentation, diagnosis, and treatment of a 42-year-old woman with a painless hard swelling-diagnosed to be intraosseous hemangioma via orbital magnetic resonance imaging-localized on the left infrao...

RATIONALE Orbital compartment syndrome (OCS) is a rare occurrence after transvenous embolization of indirect carotid-cavernous fistula (CCF). A lateral canthotomy and cantholysis are the most commonly performed surgical interventions. In our case, as the acute OCS occurred immediately after an uneventful transvenous embolization, an orbital floor orbitectomy was performed. PATIENT CONCERNS He...

INTRODUCTION Fibrous dysplasia is a benign tumour of the bones and is a disease of unknown aetiology. This report discusses a case of proptosis and visual deterioration with associated bony mass involving the right orbit. CASE PRESENTATION A 32-year-old Nigerian man of Yoruba ethnic origin presented to the eye clinic of our hospital with right-eye proptosis and visual deterioration of 7-year ...

Dysmorphology is the field of medicine focusing on congenital developmental abnormalities due to exogenous teratogens, chromosomal anomalies, or to a defect in a single gene. Numerous syndromes have been reported and a growing number of genes or chromosomal anomalies are identified. The clinical observation of the face remains an essential part of the clinical evaluation of the patients. The or...

The electronic properties of sphalerite (110) surface with Zn-vacancy and S-vacancy were calculated by using density-functional theory, and the effects of vacancy defect on the copper activation of sphalerite were investigated. The calculated results indicate that surface state occurs in the band gap of Zn-vacancy sphalerite, which is from the contribution of S 3p orbital at the first layer of ...

The lower eyelid is the most common site of tumors of the orbital region, usually of basocellular skin carcinoma, whose incidence is increasing with population aging in Western countries. The treatment must achieve the complete removal of the neoplasm in order to prevent recurrences, thus requiring eyelid and periocular reconstruction. Several techniques are described for eyelid defect reconstr...

The purpose of this article is to describe a technique for secondary reconstruction of traumatic orbital wall defects using titanium implants that act as three-dimensional (3D) puzzle pieces. We present three cases of large defect reconstruction using implants produced by Xilloc Medical B.V. (Maastricht, the Netherlands) with a 3D printer manufactured by LayerWise (3D Systems; Heverlee, Belgium...

Frontoethmoidal encephaloceles are herniations of the intracranial contents through a defect in the skull at the junction of the frontal and ethmoidal bones. They are generally classified as nasofrontal, nasoethmoidal, and naso-orbital, although there may be some overlap or multiplicity. The records of 35 patients treated for frontoethmoidal encephaloceles were examined. Of these, 12 cases with...
