Anterior nasal spine
Spina nasalis anterior
- Latin synonym: Spina nasalis maxillae
- Synonym: Nasal spine of maxilla
Definition
The anterior nasal spine forms when the nasal notch—a concave edge along the inner border of the maxilla's anterior surface—extends downward, ending in a protruding bony projection. This projection, together with a similar one from the opposite side, creates the protruding bony process known as the anterior nasal spine.
