  II. Osteology. 5b. 4. The Zygomatic Bone. Gray, Henry. 1918. Anatomy of the Human Body.
The zygomatic bone is small and quadrangular, and is situated at the upper and lateral part of the face: it forms the prominence of the cheek, part of the lateral wall and floor of the orbit, and parts of the temporal and infratemporal fossæ (Fig.
—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.
The structures attached to this tubercle are: (1) the check ligament of the Rectus lateralis; (2) the lateral end of the aponeurosis of the Levator palpebræ superioris; (3) the suspensory ligament of the eye (Lockwood); and (4) the lateral extremities of the superior and inferior tarsi.

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.
The purse string-formed plication of the SMAS is a procedure in which the soft tissue (SMAS, parotid fascia, and the extension of the supraplatysmal plane) is plicated and fixed to the periosteum of the zygomatic bone.

The segments to be implanted in the jaw bone comprise front and rear segments with non-implant areas therebetween to avoid sinus cavities.
That is, the bone of this ridge in the area of the cavities is very thin and in many cases cannot receive a recess or groove for an implant.
At the posterior or rear of the alveolar ridge of the jaw bone structure and intersecting the longitudinal line of this ridge is the pterygoid bone 14, also shown partially in section in FIG.

 Interventions for replacing missing teeth: dental implants in zygomatic bone for the rehabilitation of the severely ...
Bone is sometimes taken from somewhere else in the person's body, or bone substitutes are used.
Zygomatic implants are long screw-shaped implants developed as a partial or complete alternative to bone augmentation procedures for the severely atrophic maxilla.
One to three zygomatic implants can be inserted through the posterior alveolar crest and maxillary sinus to engage the body of the zygomatic bone.

 What is bone stimulation?
The bone stimulator is firmly held against the bone of the skull at a location known as the mastoid process (although the mandible and zygomatic arch also work) and the stimuli are produced.
The stimuli are conducted through the bone of the skull to the cochlea (which is embedded in the mastoid bone), by passing the outer and middle ears.
Peak latencies with bone stimulation are shorter because of the shorter time necessary for sound to travel through bone compared to that for the tubing of the insert earphone and the outer and middle ear.

Zygomatic bone: The part of the temporal bone of the skull that forms the prominence of the cheek.
The zygomatic bone is also known as the zygomatic arch, the zygoma, the malar bone, the cheek bone and the yoke bone.
The word "zygomatic" comes from the Greek "zygon" meaning a yoke or crossbar by which two draft animals such as oxen could be hitched to a plow or wagon.

The yield of the bone graft from zygomatic bone was quantified in cadaver and clinical studies.
In the prospective clinical study, the bone grafts from the zygomatic bone were used simultaneously with one-stage dental implants placement.
The zygomatic bone can be regarded as a safe bone harvesting donor site and the yield of bone graft from this area is sufficient for moderate defects in resorbed alveolar ridges.

A statement of the case was furnished in March 1989 on the issues of entitlement to increased (compensable) ratings for right zygomatic bone fracture residuals with scars, and for headaches.
It is asserted that sinusitis is proximately due to the service-connected residuals of a right zygomatic bone fracture, for which service connection has been established and, in any event, it is pointed out that the veteran did have symptoms of sinusitis while on active duty.
The examiner stated that it was not obvious that the veteran's symptoms were related to his zygomatic fracture, but that it was possible the veteran had recurrent bouts of sinusitis without evidence of it at the time of the examination.

 eMedicine - Orbital Fracture, Zygomatic : Article Excerpt by: Stuart R Seiff, MD, FACS   (Site not responding. Last check: )
The zygoma forms a significant portion of the floor and lateral wall of the orbit and forms a portion of the zygomatic arch, otherwise known as the malar eminence, which plays a key role in the determination of facial morphology.
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 (see Image 1).
Anatomically, the zygomatic bone contains foramina that allow for the passage of zygomaticofacial and zygomaticotemporal arteries and corresponding nerves of the second division of the trigeminal nerve that supply sensation to cheek and anterior temple.

These bones articulate at the anterior region of the skull with the frontal bone via the coronal suture and at the posterior region of the skull with the occipital bone via the lambdoid suture.
Laterally the parietal bones articulate with the temporal bones at the squamous suture.
There are three major processes arising from each temporal bone: on the lateral surface the slender zygomatic process of the temporal bone extends to articulate with the zygomatic bone.

The Frontal Process of the zygomatic forms the lateral margin and wall of the eye orbit and projects superiorly to articulate with the zygomatic process of the frontal bone.
The Temporal Process of the zygomatic runs lateral and posterior toward an articulation with the zygomatic process of the temporal bone.
Together these two processes assist in forming the zygomatic arch which serves as the attachment for the masseter muscle in life, one of the primary muscles used in mastication.
