The posterior root continues as the superior margin of the process, while the anterior root continues as the inferior margin of the process. The zygomatic process of the temporal arises by two roots, an anterior, directed inward in front of the mandibular fossa, where it expands to form the articular tubercle, and a posterior, which runs backward above the external acoustic meatus and is continuous with the supramastoid crest. Found inside – Page 70Inferiorly, its boundary is delineated by the supramastoid crest, the posterior root of the zygomatic arch, a line connecting the posterior and anterior ... The posterior wall forms the anterior border of the pterygopalatine fossa.

Zygomatic arches are sometimes incomplete (Fig. Results: The inferior temporal gyrus was always found just medial to the ZR. Its anterior root originates medially from the articular tubercle. The anterior end is deeply serrated and articulates with the zygomatic bone. The final cut is performed obliquely from posterior to anterior at the root of the zygoma and its transition point with the squamosal temporal bone. It presents two ends— anterior and posterior, and three surfaces— inferior, lateral and medial. The temporalis muscle traverses under the zygoma anterior to the root. What are synonyms for anterior root? The zygomatic bone is nearly quadrangular in shape and it features three surfaces, five borders and two processes.

Illustrated anatomical parts with images from e-Anatomy and descriptions of anatomical structures, General Anatomy > Intraorally it is a crest of bone emanating from the buccal plate of the alveolar process, lateral to the roots of the first and second maxillary molars (Fig. Posterior petrosectomy: removal of the petrous pyramid More radical or extensive transpetrosal osteotomies that have been described in the literature are often combined approaches comprised of conventional craniotomies in conjunction with an anterior or posterior petrosectomy. Posterior surface- forms the anterior wall of infratemporal fossa maxillary tuberosity- laterally it gives origin to the superficial head of the medial pterygoid muscle. The zygomatic process is occasionally referred to as the zygoma, but this term usually refers to the zygomatic bone or occasionally the zygomatic arch.
