In pure orbital blowout fractures, the orbital rim (the most anterior bony margin of the orbit) is preserved, but with impure fractures, the orbital rim is also injured. With the trapdoor variant, there is a high frequency of extra-ocular muscle entrapment despite minimal signs of external trauma, a phenomenon that is referred to as a "white ...

When zygoma fractures occur, the most typical symptoms are paresthesias in the upper lip, nose, cheek, and lower eyelid, diplopia, and pain.Particular physical characteristics that support zygomatic fracture include globe injury, impaired ocular motility, globe malposition, orbital emphysema, trismus, palpable stepoffs at the inferior or upper lateral edge of the orbit, reduced feeling ...
Fractures with displacement require surgery consisting of fracture reduction with miniplates, microplates and screws. Gillie's approach is used for depressed zygomatic fractures. [5] The prognosis of tripod fractures is generally good. In some cases there may be persistent post-surgical facial asymmetry, which can require further treatment. [6]
The Le Fort III fracture (transverse fracture) occurs at the level of the skull base, resulting in complete craniofacial separation of the midface from the base of the skull. [ 2 ] [ 3 ] The fracture line extends through the zygomatic arch , the pterygoid plates , the lateral and medial orbital walls , the nasal bones , and the nasal septum .

Orbital emphysema (/ˈɔː(r)bɪt(ə)l ˌemfɪˈsiːmə/, also known as pneumo-orbit [8]) is a medical condition that refers to the trapping of air within the loose subcutaneous around the orbit that is generally characterized by sudden onset swelling and bruising at the impacted eye, with or without deterioration of vision, which the severity depends on the density of air trapped under the ...
The Frankfurt plane is a line charted from the upper border of external auditory meatus to the lower border of the orbit. It is similar to the ala-tragus line however should not be confused with it. Whereas the Mandibular angle is a line measured along the natural lower border of the patient's mandible.
