Which videofluoroscopic view best demonstrates the symmetry of the swallow?

• A. Anterior-posterior
• B. Frontal
• C. Lateral
• D. Transverse

Answer: (A)

To judge symmetry of the swallow, you need a view that shows both sides at once. The anterior-posterior view images the swallow from the front, so you can compare left and right pharyngeal walls, tongue base, and bolus transit in real time. Any unilateral delay or residue stands out because it isn’t mirrored on the opposite side. The lateral view looks at the swallow from the side and is excellent for timing and airway protection, but it doesn’t reveal side-to-side symmetry. Transverse would slice across and miss bilateral motion, and while the frontal view can show symmetry, the view specifically used to demonstrate symmetry in VFSS is the anterior-posterior orientation.
