Sinusitis is basically an infection of the sinus cavities. There are 4 sets of sinuses:
  • Maxillary
  • Ethmoid
  • Frontal
  • Sphenoid
These cavities are air-filled cavities which are connected to the nose by small openings or Ostia.
When the openings swell up; the mucous then collects. If the openings are blocked frequently, these sinuses get infected. Think of this like a 6-lane highway that leads into a city which suddenly becomes a one-way street. This may be manifested in:
  • pressure symptoms,
  • headaches,
  • pain(cheek, teeth),
  • postnasal drip,
  • blocked nose,
  • coughing,
  • thick coloured mucus
  • etc.
 
Infections lasting 3 months or longer are defined as chronic sinusitis. The main issue with chronic sinusitis is that your body is constantly fighting an infection; this stresses your immune system and may cause chronic cough, tiredness, fatigue etc.
 
We strongly advise treatment of chronic sinusitis- this need not be surgery as often we can treat this with culture-directed antibiotics, decongestants, nasal steroids and nasal douche.
 
Occasionally if the infection is persistent, not treated properly and the sinus blocks off completely; this may result in serious complications in nearby structures such as the skin, eye, bone and the brain.
