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 zygomaticomaxillary complex fracture, also known as a quadripod fracture, quadramalar fracture, and formerly referred to as a tripod fracture or trimalar fracture, has four components, three of which are directly related to connections between the zygoma and the face, and the fourth being the orbital floor.
The role of high-dose steroids and orbital decompression in treating these patients is controversial and, if administered, must be done very soon after injury with minimal effects. In patients with an orbital fracture, vomiting or nose blowing can force air into the orbit and possibly compromise the integrity of the optic nerve.
Simple pictures showing orbital shapes are intended to describe the angular forms of regions in space where the electrons occupying the orbital are likely to be found. The diagrams cannot show the entire region where an electron can be found, since according to quantum mechanics there is a non-zero probability of finding the electron (almost ...
Spallation forces arise as the blast wave displaces a dense medium across a less dense interface, and inertial forces may cause displacement of optical structures. Primary blast ocular trauma therefore comprises non-penetrating mechanical injuries such as hyphemas, ruptured globes, conjunctival hemorrhage, serous retinitis, and orbital fracture.
Toronto Raptors forward Scottie Barnes will miss at least three weeks because of a right orbital fracture, the team said Wednesday. Barnes was struck by Denver’s Nikola Jokic while battling for ...
Miami Dolphins defensive tackle Zach Sieler, declared out for Sunday's game vs. Arizona after being poked in the eye in practice Thursday, has a fractured orbital bone, NFL Network is reporting.
It shows the ground state configuration in terms of orbital occupancy, but it does not show the ground state in terms of the sequence of orbital energies as determined spectroscopically. For example, in the transition metals, the 4s orbital is of a higher energy than the 3d orbitals; and in the lanthanides, the 6s is higher than the 4f and 5d.
