[Dysphagia] Reduced bolus driving force

[debinski at bigpond.net.au (Henry Debinski)]

An 82 year old prev fit and well female presented with dysphagia to 
solids 10 days post THR which was performed under spinal NOT GA..VF 
shows oral and pharyngeal phases which are WNL for liquids and semi 
solds. When she attempts solids, the oral phase is WNL however base of 
tongue to posterior pharyngeal wall contact appears reduced  with a 
subsequent profoundly weakened bolues driving force. Epiglottic 
retraction appears ok. The bolus remains mostly in the oropharynx 
though there is no laryngeal penetration or aspiration. There are no 
other neurological signs.  Interestingly she does comment that her 
reflux is significantly worse since surgery as well. Any thoughts on 
the cause and how to address this problem Currently she is having a 
vitamized diet and thin liquids. Aviva Melbourne Australia
