X-Ray Adenoid-which view is better-Open Mouth or close mouth

Soft tissue x-ray of Adenoid in lateral position. Compare the view obtained with open mouth and close mouth.

I often see x ray of lateral view of adenoids taken with mouth open. Perhaps that is common belief with radiology technician that all x rays ordered by ENT Surgeon have to be taken with mouth open.

You yourself note that how misleading is the x ray with mouth open. What we are seeking from this x ray is that air passage between adenoid tissues and soft palate. If we keep mouth open, then that air column never forms. So such cases many undergo mistakenly for adenoidectomy.

I hope that my radiologist and ENT friends will spread this message to x ray technicians and correct the positioning of the child for such x rays.
