Lateral nasal branch of facial artery

The lateral nasal branch of facial artery (lateral nasal artery) is derived from the facial artery as that vessel ascends along the side of the nose.

It supplies the ala and dorsum of the nose, anastomosing with its fellow, with the septal and alar branches, with the dorsal nasal branch of the ophthalmic, and with the infraorbital branch of the internal maxillary.
