The frontal process of the maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose. Its lateral surface is smooth, continuous with the anterior surface of the body, and gives attachment to the quadratus labii superioris , the orbicularis oculi , and the medial ...
Fractures of the nose, base of the skull, or maxilla may be associated with profuse nosebleeds. [1] Nasal fractures may be associated with deformity of the nose, as well as swelling and bruising. [2] Deformity in the face, for example a sunken cheekbone or teeth which do not align properly, suggests the presence of fractures.
The maxilla is a paired bone - the two maxillae unite with each other at the intermaxillary suture. The maxilla consists of: [5] Inferior surface of maxilla. The body of the maxilla: pyramid-shaped; has an orbital, a nasal, an infratemporal, and a facial surface; contains the maxillary sinus. Four processes: the zygomatic process; the frontal ...
The zygomatic process of the temporal bone is a long, arched process projecting from the lower part of the squamous portion of the temporal bone. It articulates with the zygomatic bone . This process is at first directed lateralward, its two surfaces looking upward and downward; it then appears as if twisted inward upon itself, and runs forward ...
The anterior lacrimal crest is a bony projection on the frontal process of the maxilla in the skull. [1] It reaches the junction between the maxilla and the lacrimal bone. [2] At its junction with the orbital surface is a small tubercle, the lacrimal tubercle, which serves as a guide to the position of the lacrimal sac.
The lateral or orbital surface is divided by a vertical ridge, the posterior lacrimal crest, into two parts.. In front of this crest is a longitudinal groove, the lacrimal sulcus (sulcus lacrimalis), the inner margin of which unites with the frontal process of the maxilla, and the lacrimal fossa is thus completed.
Fractures with displacement require surgery consisting of fracture reduction with miniplates, microplates and screws. Gillie's approach is used for depressed zygomatic fractures. [5] The prognosis of tripod fractures is generally good. In some cases there may be persistent post-surgical facial asymmetry, which can require further treatment. [6]
Frontal process may refer to: Frontal process of maxilla, a plate which forms part of the lateral boundary of the nose; Frontal process of the zygomatic bone, ...
