Sinus surgery still performed if having a head cold/sinus infection?

I recommend you contact your physician and schedule an appointment for an evaluation. If you have an upper respiratory infection with a history of advancing to sinusitis, it may be best to start antibiotics and Rx therapy now so that you would not be sick at the time of surgery. Most chronic nasal drainage symptoms can not always be avoided before surgery, but if you have an acute infection, most physician would prefer to postpone your surgery. The risk of complications, bleeding, pneumonia, post operative nasal infection, etc. is higher if you are sick, so it's best to avoid an elective surgery. Hope you stay well.
