Sinusitis (commonly known as a sinus infection) is inflammation, either bacterial, viral, allergic or autoimmune, of the paranasal sinuses.

signs and symptoms of sinus infection

It can be acute (going on less than three weeks) or chronic (going on more than three weeks). Sinusitis is one of the most common complications of the common cold. Sinus Infection symptoms include: Headache; facial pain; nasal congestion; fever; general malaise; thick green or yellow discharge; feeling of facial 'fullness' worsening on bending over.

Factors which may predispose to developing sinusitis include: allergies; structural problems such as a deviated nasal septum; smoking; nasal polyps; carrying the cystic fibrosis gene (research is still tentative).

diagnosis of sinus infection

X-rays may reveal thickening of the sinus lining. For chronic sinus infections, CT scanning is used. If allergy is suspected, allergy testing may be performed.

treatment of sinus infection

Therapeutic measures include simple painkillers (aspirin, paracetamol (acetaminophen) or similar), inhaling steam, hot drinks including tea and chicken soup, over-the-counter decongestants, and getting plenty of rest. If sinusitis doesn't improve within 48 hours, or is causing significant pain, one should see a doctor, who may prescribe antibiotics or nasal steroids. If left untreated, sinusitis can lead to bronchitis and pneumonia.

For chronic or recurring sinus infections, referral to an otolaryngologist is indicated for more specialist assessment and treatment, which may include nasal surgery.

A recent advance in the treatment of sinus infections is a type of surgery called FESS - functional endoscopic sinus surgery, whereby normal clearance from the sinuses is restored by removing the anatomical and pathological variations that predispose to sinusitis. This replaces the less effective Caldwell-Luc surgery.
