@jbhistory -

If you had chronic rhino sinusitis , why would your ENT only perform septoplasty/turbinate reduction?

That would not address your sinuses.

Usually someone with “CRS” is treated with oral antibiotic/oral steroid taper. 21 day antibiotics w/ a steroid taper.

Was this never offered to you pre surgery?

The lack of healthy mucociliary clearance from your sinuses, is causing the inflammed tissue/thickened secretions to drain down your throat. Typically these secretions will also run past the ET opening and cause inflammation as well.
