The anterior nasal spine, or anterior nasal spine of maxilla, is a bony projection in the skull that serves as a cephalometric landmark. [1] The anterior nasal spine is the projection formed by the fusion of the two maxillary bones at the intermaxillary suture.
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress, or at the conclusion of treatment to ascertain that the goals of treatment have been met.

The vomer (/ ˈ v oʊ m ər /; [1] [2] Latin: vomer, lit. 'ploughshare') is one of the unpaired facial bones of the skull.It is located in the midsagittal line, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones.
The piriform aperture, pyriform aperture, or anterior nasal aperture is a pear-shaped opening in the human skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and the greater and lesser alar cartilages of the nose .
The front part of this ridge rises to a considerable height, and is named the incisor crest; it is prolonged forward into a sharp process, which forms, together with a similar process of the opposite bone, the anterior nasal spine. The posterior border is serrated for articulation with the horizontal part of the palatine bone.
In human anatomy, the premaxilla is referred to as the incisive bone (os incisivum) and is the part of the maxilla which bears the incisor teeth, and encompasses the anterior nasal spine and alar region. In the nasal cavity, the premaxillary element projects higher than the maxillary element behind. The palatal portion of the premaxilla is a ...
The nasal spine (spina nasalis) may refer to: Anterior nasal spine (spina nasalis anterior maxillae) Posterior nasal spine (spina nasalis posterior ossis palatini)
The two horizontal plates join at the midline and form the posterior nasal spine that gives attachment to the musculus uvulae in the uvula. The two maxilla bones join at the base of the nose at the lower nasal midline between the nostrils, and at the top of the philtrum to form the anterior nasal spine. This thin projection of bone holds the ...
