Recurrent Rhinosinusitis or Chronic Rhinosinusitis (Sinusitis)

Recurrent Rhinosinusitis or Chronic rhinosinusitis (sinusitis) causes the spaces inside the nose and head, known as sinuses, to become inflamed and swollen. This condition persists for as long as treatment is not instituted or given adequately.

 

This condition results in excessive and purulent mucus production in the nose. The nose becomes congested as the thick mucus remains trapped within the nose and sinuses, making breathing through the nose difficult. The area around the eyes might feel swollen and tender. Other symptoms include persistent headaches and facial pain, poor sense of smell, a bad smell within the nasal cavity, persistent post-nasal drip, coughing, and persistent coloured phlegm from the nose and throat. Nasal polyps are benign growth within the nasal cavity and may cause recurrent rhinosinusitis. The condition affects both adults and children. 

 

Chronic rhinosinusitis is confirmed in two ways:

 

  • Physical examination using naso-endoscopy – a small video camera is inserted in the nose to examine the nasal passages and sinuses
  • Computed tomography (CT) scan – which utilises X-ray technology to produce a 3-D image of the nasal passages and other affected structures.

 

Treatment for sinusitis varies depending on the cause and how long the symptoms have lasted. Medication, antibiotics and nasal irrigation are given in early infection, and sinus surgery is frequently necessary in long-term, persistent sinus inflammation.
