- These are air-filled cavities in the bones of the skull that open into the nose. There are four pairs: frontal, which sits above the eyes in the forehead; maxillary, behind the cheekbones; sphenoid, behind the nose; and ethmoid, between the eyes and the bridge of the nose.
- Inflammation and swelling of the lining of the sinuses, which blocks the openings into the nose, prevents normal drainage and creates a breeding ground for further infection. Possible causes are a viral, bacterial or fungal infection, or an allergy.
- Facial pain and tenderness.
- Antimicrobials are recommended for those with severe symptoms, or persistent symptoms of at least seven days duration. Most people with acute sinusitis recover spontaneously (Stalman et al, 1997).
