Eustachian tube dysfunction/breathing disorders after rhino/septoplasty/inferior turb reduction? (photo)

It is likely only incidental that you are experiencing Eustachian tube issues after a septoplasty and rhinoplasty.  It is best to be seen by an ENT physician who can examine your nose with an endoscopy and your ear pressure.  You will likely benefit from a hearing test as well to help with your diagnosis. 

 In regards to your inferior turbinate surgery, likely your surgeon noted that they were enlarged and performed a submucous resection to increase the diameter of your nasal airway, helping you to breathe better.  This is very commonly performed, and without it your long term result may not have been as good.  Eustachian tube dysfunction is a frustrating condition

In my opinion there is no connection between a septo-rhinoplasty and a newly developed ET dysfunction. Most probably you had an underlying problem that now coincidentally started to show symptoms. The maneuvers to open the ET are correct and should help with the fluid build up. You can also try to chew sugar free gum as it constantly will open the ET due to the chewing action.Hope this helps,Dr. Gus Diaz
