 Zygomatic bone - Wikipedia, the free encyclopedia
The frontosphenoidal process is thick and serrated, and articulates with the zygomatic process of the frontal bone.
The zygomatic bone is generally described as ossifying from three centers - one for the malar and two for the orbital portion; these appear about the eighth week and fuse about the fifth month of fetal life.
It articulates with the maxilla, the temporal bone, the sphenoid bone and the frontal bone.

The floor is directed upward and lateralward, and is of less extent than the roof; it is formed chiefly by the orbital surface of the maxilla; in front and laterally, by the orbital process of the zygomatic bone, and behind and medially, to a small extent, by the orbital process of the palatine.
behind, and a little above the level of the zygomatic process of the frontal bone.
The zygomatic bone on either side forms the prominence of the cheek, the lower and lateral portion of the orbital cavity, and the anterior part of the zygomatic arch.

The soft tissue (the SMAS, the parotid fascia, and the extension of the platysma of the submandibular region) is pulled together by means of a purse string-formed suture with multiple small bites (to stay superficial) that is then fixed to the periosteum of the zygomatic bone with a periost needle.
The soft tissue is, thereby, pulled and tightened up like a purse string and sutured by a nonresorbable material at the periost of the zygomatic bone.
The author's contribution is the fixation of the SMAS and the extension of the supraplatysmal plane to the zygomatic bone periosteum to achieve stable traction and fixation.

 eMedicine - Orbital Fracture, Zygomatic : Article by Dan D DeAngelis, MD, FRCS(C)
Fractures of the zygomatic bone evoke pain on palpation in 70% of patients.
In the past, simple techniques such as exerting pressure under the zygomatic arch and resetting the bones in their anatomic position (eg, Gilles approach) were hindered by unsatisfactory cosmetic results and persistent diplopia.
Fractures of the zygomatic complex occur because of the rotation of the zygoma associated with the disarticulation of the zygomatic bone at the zygomaticofrontal suture (along the lateral orbital rim), the zygomaticomaxillary suture (medially), and along the zygomatic arch to the temporal bone.

 Maxilla - Wikipedia, the free encyclopedia
In front it forms part of the anterior surface; behind, it is concave, and forms part of the infratemporal fossa; above, it is rough and serrated for articulation with the zygomatic bone; while below, it presents the prominent arched border which marks the division between the anterior and infratemporal surfaces.
Each bone consists of a body and four processes - zygomatic, frontal, alveolar, and palatine.
(' processus zygomaticus; malar process') The zygomatic process is a rough triangular eminence, situated at the angle of separation of the anterior, zygomatic, and orbital surfaces.

interestingly they also placed great emphasis on avoiding miniplates on the zygomatic arch, the infraorbital rim, the orbital floor, and the anterior maxillary wall because of the resulting problems with inaccurate restoration, inflammatory reactions, and bone resorption 7.
Covington's study indicated that 30% of zygomatic injuries required no surgical intervention which agrees with the past literature's numbers of between 9 and 50%.
binocular diplopia occurs in 10 - 40% of zygomatic injuries and may be the result of entrapment, neuromuscular injury, hematoma, or change in orbital shape iii.

 Chiseling
While this bone serves a very important function and should be strong, in the Tervuren the Zygomatic should not be pronounced, or bowed out from the head.
This arched bone allows muscle formation to adhere to it and it is this muscle that joins the jaws and head together and gives them strength.
By having a Zygomatic that lies close to the head, both the head width is kept in check, and there will be a corresponding reduction of muscle mass, which also helps keep the cheeks flat.
