Endoscopic Sinus Surgery for Children

Endoscopic sinus surgery is a procedure to open the passages of the nose and sinuses. It is done to treat long-term (chronic) sinus infections. An ear, nose, and throat specialist (ENT or otolaryngologist) does the surgery.

This surgery is called endoscopic because a tube called an endoscope is used. This is a small, rigid tube with a light and a camera at the end. The surgeon passes the endoscope into the nose and then uses small tools to do the surgery.

Different procedures may be done. They include:

• Removal of adenoids with or without sinus wash. Adenoids are small glands behind the nose. Adenoids may cause problems with the sinuses. The sinuses may be washed (irrigated). The fluid is collected and sent to the lab to check for infection.
• Balloon sinus dilation. Small balloons are inflated along the natural drainage pathways of the sinuses to widen (dilate) them. This lets the sinuses drain better.
• Functional endoscopic sinus surgery. The surgeon uses an endoscope during surgery to open sinus passages, remove growths, or fix other problems such as deviated or crooked cartilage.

Sinus surgery is much less common in children compared with adults. In children, sinus surgery is often done only for chronic sinusitis when medical treatment has not helped. Chronic sinusitis means the infection has lasted for at least 3 months. Medical treatment includes antibiotic and corticosteroid medicines.

Surgery for short-term (acute) sinusitis is only done when a child has other serious infections near the sinuses. 

Complications of the surgery are rare but include:

• Bleeding
• Damage to the eye or eyesight
• Complications with anesthesia
• Complications with the brain, such as injury, fluid leak, or infection

The ENT healthcare provider will examine your child’s ears, nose, and throat. Your child may need tests, such as a CT scan of the sinuses. Your child’s ENT will explain your child’s surgery.

Make sure you talk with your child’s ENT about the following:

• Any medicines that your child shouldn't take before surgery. This includes over-the-counter medicines.
• When your child needs to stop eating and drinking. It is common not to eat or drink after midnight the night before surgery.
• When your child needs to arrive at the hospital or facility
• What to expect and how to care for your child after surgery
• When your child can get back to normal activities, including returning to day care or school

If your child gets sick before surgery, call theirENT. Surgery may need to be rescheduled.

The surgery often takes from 1 to 3 hours. In general, you can expect the following:

• Your child will be given medicine to sleep (general anesthesia).
• Small cuts are made inside your child’s nose.
• Using the endoscope, the ENT opens the passages of your child’s sinuses and makes the narrow passages wider.
• At this time, the ENT may wash the sinuses. The liquid is then checked for infection.
• Your child’s adenoids may be removed. This is done through the mouth.
• If needed, other procedures may be done. For example, the ENT may fix the nasal septum that divides the nose, remove the tonsils, or place ear tubes. These additional surgeries would be discussed with you beforehand and are not generally part of an endoscopic sinus surgery

Your child may need a stay in the hospital overnight or may go home the same day as the surgery.

• Your child will get IV (intravenous) fluids until going home. Your child may be given clear liquids to drink in the recovery room.
• Your child may have a sore nose, bleeding from the nose, trouble breathing through the nose, and trouble swallowing.
• Your child may be given medicine for pain or antibiotic medicine to prevent or treat infection.
• The head of the bed in the recovery room will be raised to help with swelling, breathing, and drainage. At home you should have pillows or a recliner chair available. This is to help your child keep their head raised (elevated) above chest level.
• There may be gauze or cotton packing in your child’s nose to prevent bleeding. The packing may dissolve on its own or the ENT may remove it.
• At first, there may be some drainage from the nose. The drainage may have a small amount of blood. Your child may cough or spit up some pink or brown mucus.
• Your child’s ENT may advise that your child use nasal ointment, saltwater or saline spray, or nasal steroid spray after surgery. Follow directions carefully.
• A visit with your child’s healthcare provider will be scheduled for 1 to 2 weeks after surgery. Your child will need other follow-up appointments in the months after surgery. These are to make sure that the nose and sinuses are healing as they should.
