Sinusitis is a common health issue affecting a sizeable population of all ages all over the world. Knowledge about sinusitis and modalities of its treatment has undergone significant changes over the last two to three decades.
Inflammation of sinuses – which are paired air pockets located within the bones of the face – is categorised as sinusitis. Let us get familiarised with the paranasal sinuses.
Frontal sinuses: Located above the eyes in the centre region of each eyebrow.
Maxillary sinuses: Located within the cheekbones to either side of the nose.
Ethmoid sinuses: Located between the eyes, just behind the bridge of the nose.
Sphenoid Sinuses: Located just behind the ethmoid sinuses, and behind the eyes.
Inflammation of these sinuses is called sinusitis.
Historically, sinusitis was the commonly accepted terminology for inflammation of the paranasal sinuses. This terminology has gradually been phased out in favour of rhinosinusitis because nasal inflammation almost always coincides with inflammatory paranasal sinus involvement.
Acute: up to 4 weeks,
Subacute: 4- 12 weeks
Chronic: >12 weeks
Recurrent acute: About 4 episodes/year plus each episode lasting, about 7-10 days plus no intervening signs of chronic sinusitis
Acute exacerbation of chronic: Sudden worsening of chronic rhinosinusitis (CRS), return to baseline after treatment.
