Where is a zygomatic arch fracture?
Isolated arch fractures typically occur from a single blow to the lateral cheek. If the fractures are left untreated, facial contour asymmetry, functional deficits, and psychological consequences can develop. After an isolated fracture of the zygomatic arch, trismus and impaired mouth opening are known to occur.
What part of the skeleton is the zygomatic bone?
The zygomatic bone (zygoma) is an irregularly shaped bone of the skull. It is often referred to as the cheekbone, and it comprises the prominence just below the lateral side of the orbit.
How do you tell if you break your zygomatic bone?

What happens if the zygomatic bone is damaged?
Fractures of the ZMC or zygomatic arch can often lead to unsightly malar depression, which should be corrected to restore a normal facial contour. ZMC fractures can also cause significant functional issues, including trismus, enophthalmos and/or diplopia, and paresthesias of the infraorbital nerve.
How do you fix a zygomatic fracture?
Most zygomatic complex fractures can be treated solely by an intraoral approach and rigid fixation at the zygomaticomaxillary buttress. Further exposure of the zygomaticofrontal junction or inferior orbital rim is necessary for severely displaced fractures, which require additional fixation.
What is a fractured zygoma?

Where is lacrimal bone located?
The lacrimal bones are small, flat craniofacial bones located in the eye socket. These rectangular bones consist of two surfaces, one facing the nose, the other facing the eye. Facial fractures can involve the lacrimal bone.
What 2 bones make up the zygomatic arch?
The cranial portion of the zygomatic arch is formed by the zygomatic bone, and the caudal portion is formed by the zygomatic process of the temporal bone. The zygomatic arch forms the ventral and lateral rim of the orbit.
What does your zygomatic bone do?
The zygomatic bone functions as a structure which joins the bones of the face while protecting the arteries, nerves, veins, and organs which lie below the surface. The arches of the zygomatic bone provide a person’s cheeks with the structure to fill out the face.

This surgical procedure is commonly done for patient who has a wide face due to large or prominent cheek bones.
What is an NOE fracture?
Naso-orbito-ethmoidal (NOE) fractures are complicated fractures of mid-face structure which include nasal, lacrimal, maxillary, frontal, and ethmoid bones. The central feature of NOE fracture is displacement of the medial orbital rim with the medial canthal ligament attached.
How painful is a bone bruise?
Essentially, the bone particles are compressed but not enough to cause a fracture. While bone bruises are less severe than bone fractures, they can make the bone more vulnerable to fracture. In some cases, a bone bruise can be excruciatingly painful, severely limit movements, and take several months to heal.
Can you have a fracture without swelling or bruising?

This canal opens into the inferior meatus of the nose and transmits the nasolacrimal duct.
Is the lacrimal bone part of the axial skeleton?
