Anatomical terms of bone

The anterior nasal spine is a bony projection in the skull that serves as a cephalometric landmark.

Medially, the anterior surface of the maxilla is limited by a deep concavity, the nasal notch, the margin of which gives attachment to the dilator naris posterior and ends below in a pointed process, which with its fellow of the opposite side forms the anterior nasal spine.
