Preparing for Endoscopic Sinus Surgery

Doctor talking to patient.You are scheduled to have sinus surgery. You will be asked to do some things to get ready. Be sure to follow the instructions you’re given. If you have questions, call your doctor’s office. 

Before surgery

To get ready for the surgery, you may be told to do the following:

  • Tell your doctor about all of the medicines, supplements, and herbal remedies that you take. Ask if you should stop taking them before surgery.

  • Tell your doctor if you have a pacemaker.

  • Don’t take any medicines that contain aspirin or ibuprofen for 7 days before surgery.

  • Arrange for an adult family member or friend to drive you home after surgery.

  • Follow any directions you are given for not eating or drinking before surgery.


Anesthesia is medicine that keeps you free from pain. It is given by a trained doctor called an anesthesiologist. He or she will talk to you about the type of anesthesia that will be used during surgery. You may be given one or more of the following:

  • General anesthesia. This puts you in a state like deep sleep throughout the procedure.

  • Local anesthesia. This is injected into the skin and numbs just the area being treated.

  • Monitored sedation. This makes you drowsy or slightly asleep, but doesn’t put you into a deep sleep.

  • Infection

  • Bruising

  • Excessive bleeding

  • Altered sense of taste or smell
