Nasal conditions

This Professional Assistant module looks at nasal conditions

Objectives

After studying this module, assistants will:

  • Have a basic understanding of the structure of the nose
  • Be familiar with common conditions that affect the nose
  • Know what treatment options are available to relieve these conditions.

 

Most of us probably don’t give our noses a second thought most of the time, but if we’re feeling stuffy and congested, or if our nose just won’t stop running, it certainly makes us feel under the weather.

 

To understand how conditions affect the nose, it’s important to know a little about its structure.

The nose is made up of a combination of bone and cartilage. At the top, around the bridge, the structure is bone. Towards the front, the nose is mostly cartilage and this continues inside, where a cartilage called the ‘nasal septum’ divides the nose into two halves. Air enters into each of these halves through the nostrils. Towards the back of the nose, the two nasal cavities join together.

The entire nasal cavity is lined with a membrane that produces a thin film of clear mucus. This helps humidify the air we breathe in and traps particles like allergens, bacteria and viruses. If the inside of the nose is too dry, its various functions will be impaired.
