Sinus problems

Your sinuses are four pairs of air pockets in your head. They connect to the airway in your nose. Your sinuses have several functions and play an important role in your breathing.

Mucus membranes line your sinuses. Mucus helps to keep your sinuses free of bacteria, dirt and other particles. The mucus traps particles from incoming air. These particles are then expelled by small hair-like fibres.

Healthy sinuses are clear. When sinuses are clear, mucus is able to easily pass through the sinuses and into the nose.

Blocked sinuses

Colds, allergies, infections or obstructions (e.g. a deviated septum) can inflame the mucus membrane. As the mucus becomes thicker it accumulates in the sinuses. This build-up of mucus can stop your sinus cavities from draining properly.


Your mucus membranes can become swollen if you have repeated sinus infections. Small growths can form when your mucus membranes are swollen.

Inflamed sinuses can also lead to sinusitis. Symptoms of sinusitis include fever, headaches, and pain over and underneath the eyes.


Dr Miller will examine your ear, nose and throat. He might also use X-rays, CAT scans or MRIs to see your sinuses. You might need blood or allergy tests.


Treating your sinus problems will depend on the cause of your infection:

  • We can ease or stop allergy-based sinus problems by treating the allergy. Humidifiers, a warm compress, or drinking lots of fluids can sometimes ease symptoms.
  • Medications (like antibiotics) can treat some sinus infections.
  • Sinus surgery could help if your repeated sinusitis is because of an obstruction.
