The floor (inferior wall) is formed by the orbital surface of maxilla, the orbital surface of zygomatic bone and the minute orbital process of palatine bone. Medially, near the orbital margin, is located the groove for nasolacrimal duct. Near the middle of the floor, located infraorbital groove, which leads to the infraorbital foramen.
An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall that typically results from the impact of a blunt object larger than the orbital aperture, or eye socket. [1] Most commonly this results in a herniation of orbital contents through the orbital fractures. [ 1 ]
The infraorbital vein is a vein that drains structures of the floor of the orbit. It arises on the face and passes backwards through the orbit alongside infraorbital artery and nerve, exiting the orbit through the inferior orbital fissure to drain into the pterygoid venous plexus.
the floor and lateral wall of the nasal cavity; the wall of the orbit; Each maxilla also enters into the formation of two fossae: the infratemporal and pterygopalatine, and two fissures, the inferior orbital and pterygomaxillary. -When the tender bones of the upper jaw and lower nostril are severely or repetitively damaged, at any age the ...
The zygomaticomaxillary complex fracture, also known as a quadripod fracture, quadramalar fracture, and formerly referred to as a tripod fracture or trimalar fracture, has four components, three of which are directly related to connections between the zygoma and the face, and the fourth being the orbital floor.
the superior or orbital, directed upward and lateralward; it is triangular in shape, and forms the back part of the floor of the orbit; and; the lateral, of an oblong form, directed toward the pterygopalatine fossa; it is separated from the orbital surface by a rounded border, which enters into the formation of the inferior orbital fissure.
The orbital process is a thick, strong plate, projecting backward and medialward from the orbital margin. Its antero-medial surface forms, by its junction with the orbital surface of the maxilla and with the great wing of the sphenoid , part of the floor and lateral wall of the orbit.
The infraorbital groove (or sulcus) is located in the middle of the posterior part of the orbital surface of the maxilla. Its function is to act as the passage of the infraorbital artery , the infraorbital vein , and the infraorbital nerve .
