A 10-year-old Chinese girl with two accessory maxillae and bilateral Tessier no. 7 clefts is presented. Radiographic examination showed two accessory maxillae, each containing 5 or 6 supernumerary permanent teeth. The two accessory maxillae extended from the inside of the zygomatic arch to the maxillary tuberosity symmetrically. Duplication of the maxilla is always associated with Amniotic Band...

A young male presenting with a history of progressive midfacial symmetry and limitation of mouth opening was found to have a unilateral coronoid hyperplasia forming an osteochondromatous pseudojoint with the expanded zygomatic arch (Jacob’s disease). This paper reviews the differential diagnoses of problems, especially in developing countries, that can cause restricted mouth opening, highlighti...

At the time of weaning, infant animals have little experience with hard food, and thus their skulls are not likely to be epigenetically adapted for the loads imposed by mastication. We examined bone strain in the zygomatic arch of 4-week-old weanling piglets. Functional strains in piglets differed from those previously reported for older pigs in that the squamosal bone was not bent in the horiz...

OBJECTIVE To test the validity of the subzygomatic fossa as a possible landmark in identifying the origin of the zygomaticus major muscle (ZMM). METHODS Twenty-three fresh cadaver facial halves were dissected. Four references points were identified in each cadaver head: the zygomatic arch, the malar eminence, the modiolus, and the ZMM insertion notch. The ZMM insertion notch is a palpable lan...

AIM The superficial temporal artery is one of the main terminal branches of the external carotid artery. This artery ascends through the lateralposterior margin of the zygomatic arch to reach the temporal region of the scalp. The superficial temporal artery divides its frontal and parietal branches around the zygomatic arch. MATERIAL AND METHODS The raw data of the Three-dimensional Computeri...

F c ince the first description of a surgical reduction of a ygoma fracture by Duverney in 1751, many varying ethods of treatment have been described. Both inraoral and extraoral methods have become commonlace. The transoral approach was popularized by Keen n 1909, with later modifications by Goldthwaite and uinn. These techniques offer the advantages of avoidng any skin incision, thereby avoidi...

Neuralgia of the infraorbital nerve is an unusual cause of facial pain. The patient experiences paroxysmal or constant discomfort, often in the form of stabbing pain, in the distribution area of the infraorbital nerve. The sensation is associated with hypersensitivity to palpation in the infraorbital notch. The infraorbital nerve is a branch of the maxillary nerve. It originates in the infraorb...
