What are symptoms of aspiration due to silent reflux?

Symptoms of silent: Reflux or laryngopharyngeal reflux usually are centered around the voice box area. Aspiration is not common but cost is. The vocal cords reflexively close when sensing foreign material going into the area. If it is severe you could develop vocal cord dysfunction. Patients commonly complain of sensing a lump in the throat, also known as globus.

Cough/wheeze/hoarse: There is a defined association between gerd and aspiration leading to asthmatic symptoms, chronic cough, chronic hoarseness, pharyngitis, laryngitis, etc all the above are rarely silent though and pt does give a proper history of gerd. Though the association has been well defined in clinical practice its difficult to prove. Hope this helps.
