Sinusitis​

Sinuses are small air-filled spaces within the skull or bones of the head surrounding the nose. Sinusitis is an inflammation of the tissues and membranes lining the sinuses. Because of this, the sinuses, which are usually filled with air, become filled with germs-containing fluids as the swelling and inflammation traps mucus, leading to an infection.

Sinusitis can be caused due to other nasal disorders, such as a deviated nasal septum, common cold, allergic rhinitis or nasal polyps. It can also be caused due to exposure to chemicals or irritant substances which cause irritation in the sinuses. 

There are different types of sinusitis, such as:

• Acute sinusitis: Sudden onset of sinusitis
  

• Chronic sinusitis: A persistent sinus infection over a prolonged period (over eight weeks)
  

• Subacute sinusitis: A sinus infection lasting longer than acute sinusitis but less than chronic sinusitis.
  

• Recurrent sinusitis: Repeated episodes of sinus infections throughout the year

People who have allergies, asthma, or a generally weaker immune system are at a greater risk for developing sinusitis. ​

When to seek expert advise

Symptoms of sinusitis improve on their own within two to three weeks. However, if you face the above-mentioned symptoms for a prolonged period of time, you must see your doctor. If your symptoms do not show any improvement after three to four weeks, you must schedule an appointment with an ENT specialist working with the Eye and ENT Service Line of The Aga Khan University Hospital. Fever along with sinusitis symptoms is also a cause for concern, necessitating further evaluation of your symptoms by the doctor.
