Maxilla - Wikipedia, the free encyclopedia

In front of the opening of the sinus is a deep groove, the lacrimalb> groove, which is converted into the nasolacrimal canal, by the lacrimalb> bone and inferior nasal concha; this canal opens into the inferior meatus of the nose and transmits the nasolacrimal duct.
In old age the bone reverts in some measure to the infantile condition; its height is diminished, and after the loss of the teeth the alveolar process is absorbed, and the lower part of the bone contracted and reduced in thickness.
Each bone consists of a body and four processes - zygomatic, frontal, alveolar, and palatine.

The axial skeleton Chapter 7

Articulations: The ethmoid bone articulates with the frontal and sphenoid bones of the cranium and with the nasal, lacrimalb>, palatine, and maxillary bones and the inferior nasal conchae and vomer of the face (Figures 7-3c,d, 7-4a, and b).
The adult vertebral column, or spine, consists of 26 bones: the vertebrae (24), the sacrum, and the coccyx, or tailbone.
The styloid process, near the base of the mastoid process, is attached to ligaments that support the hyoid bone and to the tendons of several muscles associated with the hyoid bone, the tongue, and the pharynx.

0.3 or 0.4 mm stainless steel wire is passed through the tendon or bone twice; the ends are then passed transnasally through pre-drilled holes in the opposite anterior lacrimalb> crest with a curved awl or curved spinal needle 7.
superior stabilization is obtained, however, by wiring the bone fragment transnasally to the opposite anterior lacrimalb> crest 6.
the frontal process of the maxilla and the nasal bones should be aligned with the frontal bone and directly wired 1.
