Sinus Endoscopy with Balloon Dilation - Sinuplasty

This surgery uses small instruments to examine the inside of the sinuses and widen a blocked or narrowed opening.

This surgery uses small instruments to examine the inside of the sinuses and widen a blocked or narrowed opening.

The sinuses are air-filled spaces located behind the forehead, nasal bones, cheeks and eyes.

  • Normally, mucus drains from the sinuses so air can flow freely.
  • Occasionally, swelling can block the nasal passages and stop the mucus from draining. This can lead to pain and chronic sinus infections.

Nasal endoscopy is an examination of the inside of the nose and sinuses. It is done by placing a special catheter through the nose into the sinuses. After the sinuses are examined, a special catheter is placed in a narrowed or blocked area of the sinus. Then a small balloon at the end of the catheter is inflated. This is called a sinuplasty.

  • When the balloon is inflated it pushes the bone and mucous membranes outwards.
  • This widens the passageway to the sinus without removing any tissue.

A sinuplasty may be recommended If you have repeated sinus infections that do not respond to medical treatments. However, a sinuplasty is not effective in certain situations, such as:

  • Treating nasals polyps (small growths in the nasal cavity)
  • When a lot of scarring is present in the openings to the sinuses

Sinuplasty can be done in an office, hospital or ambulatory surgery center (ASC). During the procedure, you will receive some type of anesthesia to keep you comfortable and pain free.

  • General anesthesia is when you are put into a deep sleep and are unable to see, hear or feel anything.
  • Local anesthesia is when your nose is numbed and you are given medication to keep you relaxed.

Special packing or splints may be placed inside your nose to help it heal properly. Your healthcare provider will let you know when to have them removed. The area where the balloon was inflated may be sore and bleed for a few days.

Prior to the procedure, tell your healthcare provider about any medications you are taking (including over-the-counter medications and supplements). Ask about specific instructions you should follow before and after the surgery. These may include:

  • Medications you should not take before the procedure, such as blood thinners or aspirin
  • Regular medications you should continue to take on the day of your procedure
  • How many hours you should stop eating and drinking before the procedure

What should I ask my healthcare provider before having a sinuplasty?

  • What is my diagnosis and reason for the procedure?
  • What are the possible complications for this procedure?
  • Are there any alternatives to this procedure? What are the benefits and risks of each?
  • Is there any special preparation for the procedure? (If so, get clear instructions on what you need to do.)
  • What type of anesthesia will I have? What are the possible side effects?
  • How will I feel after the procedure and will I have to modify my activity?
