purpose: to determine the normal values of bony inter- and intra-orbital distances in an iranian adult population by orbital ct scan. methods: the study was conducted on all adults who were referred to farabi eye hospital from march 2003 to june 2005 for ct scan ordered for complaints unrelated to craniofacial or orbital abnormalities. patients were excluded in the presence of any pathology of ...

The distance between the orbits and their individual dimensions are important in the diagnosis of craniofacial anomalies. Most observers rely on standard radiographs for measuring the bony interorbital distance. Tomography of the skull base and orbital computed tomography (CT) can also be used. This article describes the normal range of the bony interorbital distance and other useful orbital li...

BACKGROUND Facial aging is a dynamic process involving the aging of soft tissue and bony structures. The shape, size, and volume of the bony orbit have all been shown to change with increasing age. OBJECTIVE In this study, we demonstrate how specific bony aspects of the orbit change with age in both male and female subjects and what impact this may have on the techniques used in facial cosmet...

BACKGROUND AND PURPOSE The infraorbital nerve arises from the maxillary branch of the trigeminal nerve and normally traverses the orbital floor in the infraorbital canal. Sometimes, however, the infraorbital canal protrudes into the maxillary sinus separate from the orbital floor. We systematically studied the prevalence of this variant. MATERIALS AND METHODS We performed a retrospective revi...

PURPOSE To determine the dimensions of orbital entrance in unaffected bony orbit by computed tomography (CT) in a sample of Iranian population. METHODS Radiologic features of 120 patients were gathered using standardized skull protocol by CT scan. We measured the distance between anterior lacrimal crest and orbital border of zygomatic bone, termed width, and the distance between the plane pas...

The bony orbit surrounding the eye is pyramidal with a rectangular base. The orbital volume (OV) of an adult is approximately 30 mm3 [1]. However, measurement of OV can be inconsistent due to the complicated anatomical structure of the bony orbit including the irregular inner border, holes and fissures. Computed tomography (CT) provides excellent image quality of bony landmarks making it a popu...

The so-called meningo-orbital foramen creates an additional link between the orbit and the cranial cavity. This bony canal, not always present in the human skull, contains a branch from the middle meningeal artery, providing an accessory blood supply to the orbit. This vessel, like the foramen, is characterised by great variability. Although older textbooks of basic anatomy suggested that it wa...

Benign mesenchymal tumors of the craniofacial complex present unique challenges for orbital surgeons because of their potential for orbital compartment syndrome, ocular morbidity, and facial disfigurement and because definitive surgical management may be associated with significant morbidity. While the precise classification of such lesions depends on radiologic as well as histologic evaluation...

Background & Aims: The orbital cavity is an important anatomic structure in the face. It is in close connection with the skull, paranasal sinuses, and the nose. Precise knowledge of the orbital cavity dimensions can be helpful in the diagnosis and treatment of diseases associated with the orbital cavity. Due to the lack of adequate research on orbital size in Iran and the city of Kerman, the ai...
