Sinus Surgery

I have had chronic paranasal sinus pressure for 3 months for the first time in my life (age 44) after a very bad cold.  A sinus CT shows a badly deviated septum, which is the result of breaking my nose at the age of 2. A brain MRI with contrast was also done and shows nothing wrong. Still, I have left ear pain and sinus pressure that gets worse during the day, gone at night when lying down.

My ENT says surgery to fix the septum will alleviate the symptoms.  However, I do not understand why, if my nose has been this bad for 42 years, is this manifesting itself now?

There is no easy answer to your question of why now, at age 44.  Our bodies change over time and this includes our resistance to infection, both local in the nose and sinuses and systemic with our immune system.  It might also be that you were not before exposed to the infectious agent, or the magnitude of the exposure, that has caused your problem for the past few months.  It is very likely that your ENT is correct
