In the human skull, the zygomatic bone (from Ancient Greek: ζῠγόν, romanized: zugón, lit. 'yoke'), also called cheekbone or malar bone , is a paired irregular bone , situated at the upper and lateral part of the face and forming part of the lateral wall and floor of the orbit , of the temporal fossa and the infratemporal fossa .
ZMC complex fractures involve the lateral vertical buttress of the ZMC complex (lateral maxillary sinus and lateral orbital wall) and the upper transverse buttress (inferior orbital rim and floor, also including the zygomatic arch). Three of its four components are directly related to connections between the zygoma and the face.
Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.
The zygomatic process forms an "L" in this picture. As a comparison, this is how the skull looks with almost all of the zygomatic process removed. The zygomatic processes (aka. malar) are three processes (protrusions) from other bones of the skull which each articulate with the zygomatic bone. The three processes are: [1]
When discussing the anatomy of the face, it is often divided into thirds. The lower third extends from the chin to approximately the level of the upper teeth. The middle third continues from the teeth to just below the brow line. Finally, the upper third stretches from the brow to the hairline. [3] The facial skeleton
In anatomy, the zygomatic arch (colloquially known as the cheek bone), is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); [1] the tendon ...
The maxilla is a paired bone that forms a significant portion of the midface. It articulates with the frontal, zygomatic, palatine bone, and sphenoid bones. The Le Fort I segment, the portion of the maxilla mobilized during the osteotomy, receives its blood supply primarily from the ascending palatine artery (a branch of the facial artery) and the anterior branch of the ascending pharyngeal ...
The zygomatic bone is denser in quality and more cortical in nature than posterior maxillary bone. [5] Because of the sturdy anchorage achievable in the dense bone of the zygomatic region, and the wide stress distribution achieved on these tilted implants, a prosthesis can often be immediately placed at the time of surgery.
