In the images that you attached the passage doesn’t seem to be visible. I guess it’s blocked by the tongue. If it’s possible to ask the patient to breathe through the mouth during imaging then probably the passage would be visible.

You can still connect the pharynx and oral cavity by painting a passage using Paint or Draw effect where you expect it to be. Or, you can contour the tongue, tonsils, palate, etc. with different segments and the passage is at the boundary surface of segments.
