d d s a ecause of the complex structure of the orbital walls, he fracture patterns vary considerably in their locaion as well as in their degree of severity.1 Multiple ortions of the orbit can be fractured and several nternal orbital walls therefore injured simultaeously. The ideal reconstruction material for orbital floor or all reconstruction should be easy to mold, easy to nchor, biocompatib...

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...

PURPOSE To analyze the correlation between the volume of herniated orbital contents and the amount of enophthalmos in orbital floor and wall fractures. MATERIALS AND METHODS Patients with secondary enophthalmos due to unilateral orbital floor and wall fractures were recruited. Computed tomography-assisted measurements of both orbits as well as of the amount of enophthalmos were performed. The...

AIMS A modified surgical technique is described to perform a one, two, or three wall orbital decompression in patients with Graves' ophthalmopathy. METHODS The lateral wall was approached ab interno through a "swinging eyelid" approach (lateral canthotomy and lower fornix incision) and an extended periosteum incision along the inferior and lateral orbital margin. In addition, the orbital floo...

BACKGROUND The mechanism of injury and the underlying biomechanics of orbital blowout fractures remain controversial. The "hydraulic" theory proposes that a generalized increased orbital content pressure results in direct compression and fracturing of the thin orbital bone. OBJECTIVE To examine the pure hydraulic mechanism of injury by eliminating the factor of globe-to-wall contact and its p...

External impact to the orbit may cause a blowout or zygomatico-maxillary fractures. Diagnosis and treatment of orbital wall fractures are based on both physical examination and computed tomography scan of the orbit. Injuries of the orbit often require a reconstruction of its orbital walls. Using computer-assisted techniques, anatomically preformed orbital implants, and intraoperative imaging of...

The term blow-out fracture was co ined by Smith and Regan [1] to describe an orbital floor fracture caused by a very sudden increase in intraorbital pressure without concomitant fracture of the orbital rim . Most blow-out fractures involve the orbital floor. Less often the medial orbital wall is fractured either solely or in conjunction with a fracture of the floor [2]. Upward displacement frac...

The zygoma forms part of the floor and lateral wall of the orbit and the zygomatic arch is an important feature in the structure and appearance of the face. The malar complex refers to the zygoma and maxillary bones (and therefore forms part of the orbital floor and lateral orbital wall). This plays a key role in the structure and function of the facial skeleton. In addition to providing suppor...
