Maxillary sinus puncture

sinus puncture · antral puncture · sinus washout · sinus lavage for sinusitis

The doctor makes a small hole with a thin needle through the nose into the sinus and rinses it. This lets the pus out.

For sinusitis with pus when medicines do not help, or to take a sample for testing.

⏱ Duration: usually 10 to 20 minutes

Be sure to tell your doctor

How to prepare

  • Scan. An X-ray or CT scan of the sinuses is usually done first.
  • Food. You can have a light meal beforehand.
  • Medicines. Do not stop your medicines on your own. Tell the doctor.

What to bring

  • Your ID
  • Your sinus scans
  • Tissues

How it goes

  1. The doctor numbs your nose with a spray or a cotton pad
  2. You sit with your head tilted a little
  3. A thin needle is passed through the wall of the sinus
  4. The sinus is rinsed with a solution through the needle
  5. Fluid and pus drain out through your nose into a tray
  6. The needle is removed

What you'll feel

  • The numbing medicine stings a little
  • During the puncture, you hear a crunch and feel pressure
  • Rinsing feels like fullness in your cheek

Afterwards

  • A little blood from the nose usually stops quickly
  • Do not blow your nose hard for the first few hours
  • Further rinses and medicines are as your doctor prescribes

Contact a doctor straight away if

  • A heavy nosebleed
  • Swelling of the cheek or eyelids, or eye pain
  • A fever over 38°C after the procedure
  • A severe headache or vomiting: call emergency services

Common questions

If I have one puncture, will I always need them?

No. This is a myth. A puncture does not make you dependent on it.

Does it hurt?

With numbing medicine, it usually does not hurt, but it is unpleasant.
