It runs obliquely forward, between the pterygoideus internus and the insertion of the temporalis, to the outer surface of the buccinator, to which it is distributed, anastomosing with branches of the facial artery and with the infraorbital. From the infraorbital area, it descends bilaterally in the superficial face along the lateral margin of the nose, then running anti-parallel to the facial artery across the lateral oral region.
