Nose Still Blocked Nearly 3 Months Post Op Septoplasty and Turbine Reduction?

It can take many months for all of the swelling to resolve inside the nose after a septoplasty and turbinate reduction. Any ongoing allergic rhinitis or sinusitis symptoms may contribute, and sometimes nasal steroid sprays can be helpful. If there is persistent crusting or dryness after surgery, this could be contributing as well. Finally, be sure to discuss any post-operative concerns with your surgeon so that they can fully examine you and rule out excess scar tissue, crusting, etc.
All the best,

I like your username Septoman.  By 3 months, your septum and turbinates should be nearly healed.  If you have residual nasal obstruction, it could be a result of any of the factors you mentioned, including: deviation, recurrent turbinate hypertrophy, crusting, or another structural change that is obstructing your breathing.  Without examining your nose determining the reason is guess-work, so it's best to touch base with your surgeon.  Once you know the cause, the appropriate treatment can be initiated.  

By 3 months post-op, the surgical swelling should be resolved inside the nose.  It is possible that another cause of swelling, such as allergic rhinitis (nasal allergies) could play a role.  If you are experience sneezing, and itchy sensation in the nose, or nasal discharge, these could be signs of allergy.  If your left side was open initially after surgery and only recently has become blocked, I think an inflammatory (swelling) issue is causing the problem. If it was blocked immediately after surgery, it could be a structural issue, possibly related to the surgery itself.  You should address these issues with your surgeon who should be able to guide you.
