Sinus Infection

Sinusitis and upper airway disease

What is Sinusitis?

The sinuses are hollow cavities in the skull. They are divided into the frontal, maxillary, ethmoid and sphenoid sinuses. All sinuses are filled with air and, like the nose, are lined with a mucous membrane where a fine film of mucus is constantly formed. Their job is to stop dust, dirt particles or undesirable pathogens from entering the respiratory tract.

Upper Respiratory Infection a.k.a. the common cold – a common trigger

The mucus film, along with any particles of dirt that are breathed in are continuously transported towards the sinuses and throat by very fine hairs. This helps to keep this area free of dust and germs. Having a cold can cause inflammation of the mucous membrane. It suddenly produces much more mucus and swells the nasal passage. This can obstruct the fine connections between the nose and the sinuses. The mucus cannot drain as well or cannot drain at all, which causes it to build up and become the ideal breeding ground for germs that can trigger acute sinusitis.

Acute or chronic sinusitis?

Usually sinusitis resolves after a few weeks. There are a variety of factors that determine whether sinusitis, called rhinosinusitis, recurs or develops into a chronic disease. These include the body’s own defense system, predisposition to allergies or anatomical conditions: e.g. nasal polyps or a curved nasal septum.
