Maxillary Sinusitis:
Common and Treatable ↓

Did you know the first person to illustrate the Maxillary Sinuses was Leonardo da Vinci? Although it was surely a pretty picture, Maxillary Sinusitis is not.

The maxillary sinuses are located behind your cheek bones and are amongst the largest of your paranasal sinuses. It is also the most common place for your to develop a sinus infection.

Maxillary Sinusitis Causes

The Maxillary Sinuses are located behind your cheek bones.
  • Allergies
  • Viruses
  • Bacteria
  • Facial Trauma
  • Deviated Septum
  • Nasal Polyps

When an infection occurs in the maxillary sinuses, the passages get blocked and are unable to drain.

Small tubes running from the sinuses to the nasal passages called ostium, become irritated and swell preventing drainage.

Mucus gets trapped within the sinuses and causes pain and pressure in the face. The cause of this infection ranges from allergies, viral, bacterial, or fungal. Other causes for Maxillary Sinusitis are facial trauma, nasal polyps, or deviated septum.


  • Post Nasal Drip
  • Mucus Discharge
  • Facial Pressure
  • Swelling Around Cheeks and Eyes

Fight the Infection
Maxillary Sinusitis Treatment usually includes antibiotics if the infection is caused by bacteria. If your Maxillary Sinusitis is caused by a viral infection, you will not be prescribed antibiotics as they are not an effective medication to treat this type of infection.

Reduce Swelling and Drainage
Decongestants can help to clear nasal passages by reducing swelling. Nasal sprays (over-the-counter or prescribed) also work to help with the drainage of mucus, though should be used strictly as directly. Dependency can occur with nasal sprays if used in excess and could actually cause further damage.

Soothe and Relieve
Other remedies for the relief of Maxillary Sinusitis include warm compressed with a washcloth on the face and head and steam treatments. Steam treatments with a hot bowl of water and towel over your head while breathing in the steam, help to keep your nasal and sinus passages moist. This will also help to expel the build-up of mucus and is recommended to be repeated 3-4 times daily.

A salt water nasal wash (also repeated 3-4 times daily) is another, more natural solution to using nasal sprays which has proven to be effective. Over-the-counter pain relievers can help with the pressure felt and to fight against headaches that may occur.

See A Doctor

It is important to seek medical attention if your symptoms of Maxillary Sinusitis last more than a few days. More serious complications could occur if left untreated. If you have been taking medication and you do not feel yourself getting better, make sure to follow up with your doctor. It is sometimes necessary to have a surgical procedure, though is it not common.
