The most common FA type was the lateral nasal type, which predominantly coursed medial to the nasolabial fold. In the infraorbital region, areas outside 1.64 cm (right) and 1.55 cm (left) of the rhinion represent lower vascular density zones. For the medial nasolabial fold, areas closer than 1.53 cm (right) and 1.46 cm (left) from the anterior nasal spine superiorly, and nearer than 2.23 cm on the right and 2.07 cm on the left from the alveolar process of the maxilla inferiorly, represent lower vascular density zones relative to the FA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A detailed anatomical framework of the FA and FV was established, providing a stable reference for anatomical navigation and vascular clinical risk mitigation.
