Which of the following statements is (are) correct regarding the parietoacanthial projection (Waters' method) of the skull?
Alecsey [184]

Answer:

The correct answer is 1: In Waters´ method, the head is rested on the extended chin.

Explanation:

The parietoacanthial projection (Waters' method) is a widely used radiography method that demonstrates if there are any facial bone fractures, inflammation, or foreign body in the patient skull.  

The patient must be in an erect position or prone. They must rest their head on the tip of the <u>extended chin</u> against the table surface. The neck must be hyperextended so that the orbitomeatal line (OML) forms a 37-degrees angle with the plane of the image receptor (IR). This is<u> not perpendicular to IR</u>, as <u>perpendicular means</u> that a <u>90-degree angle</u> must be formed. The mentomeatal line (MML) must be perpendicular to the image receptor plane. Finally, the midsagittal plane must be perpendicular to the plane of the image receptor.
