Case

A 41 year old patient is admitted with a fracture of both the left and right inferior orbital rim resulting in an instability of their maxilla.

Question 3/3 - Starting at the aorta going to the right side of the face, what is the correct sequence of arteries to reach the deep nasal branches that would be injured in the Le Forte fracture. 

Click on your selected option(s) below  (correct = 2, over-thinking = 3+)

Incorrect. The right common carotid artery does not directly connect to the aorta, it is a branch of the brachiocephalic trunk.

Incorrect. There are no branches in the neck from the internal carotid artery, all neck branches are from the external carotid.

Correct. This pathway provides deep branches that enter the nasal bones, a fracture through this region could rupture these vessels

Correct. This pathway brings blood through the superficial tissues of the face to the nasal region, where the vessels anastomose from the angular to the nasal branches.

The superficial and deep systems anastomose, so the vessels can be supplied either from the facial artery system or the maxillary artery system.

Incorrect. The inferior labial branches lead to the mandible, not to the nasal region

Incorrect. The carotid system starts as a common carotid (from the brachiocephalic trunk on the right or directly from the aorta on the left), which then splits into the external and internal carotid arteries.
