[Dysphagia] Silent aspiration

[Paula.Leslie at newcastle.ac.uk (Paula leslie)]

I am curious about how exactly CA allows one to detect "silent aspiration" 
when, to my knowledge, there is no evidence that shows aspiration (silent or 
otherwise) linked to any sound made before, during or after swallowing.  We 
need videofluoroscopy or laryngoscopy images ie direct visualisation done on 
the same swallow not just the same patient at a different time.  Anything else 
is just presumption of a link.  People do talk of wet breath sounds but again 
there is no evidence of what exactly this is.

Features such as coughing, wet voice, stridor etc do not need CA to be 
detected.

People may have such data from simultaneous swallow studies, ie CA AND VF/LSE 
done at the same time.  If so it would be very useful to get them into the 
public domain to increase the evidence base on this topic.
