The two nostrils are divided by a wall called the nasal septum. The septum is rich in blood vessels. If they bleed regularly, the blood vessels can be sealed with nasal cautery.

Nasal cautery is a type of surgery (operation) to treat nose bleeds. It involves using electricity to seal blood vessels in the nose that bleed regularly.

Does my child need to do anything to prepare for nasal cautery?

There is no special preparation for nasal cautery. The doctor examines each nostril to look for the bleeding point and any other possible causes of bleeding.

What happens during surgery?

Before the surgery, your child will have a special “sleep medicine” called a general anaesthetic. This will make sure your child sleeps through the operation and does not feel any pain.

The surgeon will then use an instrument called an electrocautery needle to pass electricity to the area of the nosebleeds. The electricity burns the tissue slightly where bleeding usually occurs. When the tissue heals, it becomes thicker. This prevents further nosebleeds.

What happens after surgery?

Once the surgery is finished, the surgeon will use a special sponge, such as Gelfoam or Surgicel, to pack your child’s nose. The surgeon will also fill the nose with Polysporin. Together, the packing and Polysporin protect the burned tissue in your child’s nose while it heals. The packing will dissolve after three to five days.

Your child will usually then be sent home on the same day as the surgery.

How do I care for my child at home?

Your child’s nose will feel congested (blocked) for up to one week after surgery. As a result, they may find it difficult to breathe through their nose. This is normal.

  • If your child is in pain, you can give them acetaminophen (for example Tylenol). Avoid giving ibuprofen​ (for example Motrin or Advil) for two weeks after cautery.
  • If there is crusting in your child’s nose, use a saline spray two to four times a day to loosen it. You can start using the spray three to five days after surgery or once the packing has dissolved.
  • If your child’s nose feels dry or irritated, use Polysporin or Vaseline to lubricate (moisten) it.
  • Consider using a cool air humidifier at night while your child is sleeping. This will keep the air moist and be more comfortable for your child while their skin is healing from the surgery.
  • Have your child sleep in a slightly upright position, supported by pillows, for the first week or so after surgery. This may be more comfortable for your child than lying flat in the bed.

What your child must avoid after nasal cautery

For the first week after surgery, your child must not:

  • blow their nose – they can wipe it gently with a tissue instead;
  • bend over or lift anything heavy
  • take part in any activity that requires a lot of energy, such as swimming or contact sports like hockey or football
  • pick their nose – if your child picks their nose at night, it may help them to sleep with socks on their hands.

What your child can do

Your child can return to normal activity as soon as they feel able.

When should I call a doctor?

Call your doctor if:

  • your child has a fever (a temperature of 38°C (100°F) or higher)
  • your child has a nose bleed that does not stop after 20 minutes of continuous pressure to the nose
  • there is any vomiting with specks of blood
  • a foul smell or green fluid comes from your child’s nose.
