An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall that typically results from the impact of a blunt object larger than the orbital aperture, or eye socket. [1] Most commonly this results in a herniation of orbital contents through the orbital fractures. [1] The proximity of maxillary and ethmoidal sinus ...
An ocular prosthesis, artificial eye or glass eye is a type of craniofacial prosthesis that replaces an absent natural eye following an enucleation, evisceration, or orbital exenteration. The prosthesis fits over an orbital implant and under the eyelids. Though often referred to as a glass eye, the ocular prosthesis roughly takes the shape of a ...
A craniotomy is a surgical operation in which a bone flap is temporarily removed from the skull to access the brain.Craniotomies are often critical operations, performed on patients who are suffering from brain lesions, such as tumors, blood clots, removal of foreign bodies such as bullets, or traumatic brain injury (TBI), and can also allow doctors to surgically implant devices, such as deep ...
Zygomaticomaxillary complex fracture. Right zygomaticomaxillary complex fracture with disruption of the lateral orbital wall, orbital floor, zygomatic arch and maxillary sinus. The zygomaticomaxillary complex fracture, also known as a quadripod fracture, quadramalar fracture, and formerly referred to as a tripod fracture or trimalar fracture ...
Frontal bone. Inner surface. (The Pars orbitalis is the bottom third.) The orbital or horizontal part of the frontal bone ( pars orbitalis) consists of two thin triangular plates, the orbital plates, which form the vaults of the orbits, and are separated from one another by a median gap, the ethmoidal notch .
Zygoma reduction, also known as cheekbone reduction surgery, is a surgery used to reduce the facial width by excising part of the zygomatic bone and arch. Wide cheekbones are a characteristic facial trait of Asians, whose skull shapes tend to be more brachycephalic (broad, short skull) in comparison with Caucasian counterparts, whose skull shapes tend to be more dolichocephalic (narrow and ...
Craniosynostosis is a condition in which one or more of the fibrous sutures in a young infant's skull prematurely fuses by turning into bone (ossification), [2] thereby changing the growth pattern of the skull. [3] Because the skull cannot expand perpendicular to the fused suture, it compensates by growing more in the direction parallel to the ...
The superior bony margin of the orbital rim, otherwise known as the orbital process, is formed by the frontal bone. The roof (superior wall) is formed primarily by the orbital plate frontal bone, and also the lesser wing of sphenoid near the apex of the orbit. The orbital surface presents medially by trochlear fovea and laterally by lacrimal fossa.
