The anterior nasal spine, or anterior nasal spine of maxilla, is a bony projection in the skull that serves as a cephalometric landmark.{{cite journal |last1=Albarakati |first1=SF |last2=Kula |first2=KS |last3=Ghoneima |first3=AA |title=The reliability and reproducibility of cephalometric measurements: a comparison of conventional and digital methods. |journal=Dento Maxillo Facial Radiology |date=January 2012 |volume=41 |issue=1 |pages=11–7 |doi=10.1259/dmfr/37010910 |pmid=22184624|pmc=3520271 }} The anterior nasal spine is the projection formed by the fusion of the two maxillary bones at the intermaxillary suture. It is placed at the level of the nostrils, at the uppermost part of the philtrum. It rarely fractures.{{cite web |last1=Knipe |first1=Henry |title=Anterior nasal spine fracture {{!}} Radiology Case {{!}} Radiopaedia.org |url=https://radiopaedia.org/cases/anterior-nasal-spine-fracture |website=radiopaedia.org |access-date=13 October 2018 |language=en}}
