7 days post op Rhino septoplasty, I can't taste or smell anything. My surgeon says it's normal, Is it really?

This is common at this
early stage. Your sense of smell and taste can often take many weeks to return.

It is very normal to not have taste/smell postoperatively for up to 6 weeks.  The swelling on the inside of your nose impedes air flow which impedes smell and taste.  This is very similar to having a cold, where you cannot smell and taste.It will improve.  :)

The swelling likely to be causing you to not have normal taste and smell senses.  The majority of our ability to taste comes from our ability to smell. Your swelling/congestion is inhibiting this right now but this will recover fully in time. Try to continue to be patient as you continue to heal. I wish you a speedy recovery!Mark Petroff, MD
