Overview of Sinusitis
Sinuses are a series of hollow, interconnected cavities in the skull. Anatomically, the sinuses are lined with a thin, soft layer of tissue called the mucosa, similar to the one found in the nose. They are normally empty, save for a thin lining of mucous. These sinuses drain into the nose through a small passage.
Physiologically, the function of the sinuses is unclear, scientists have theorized that they help to amplify our voices, other theorize that they warm the air that we breathe.
Sinusitis symptoms are noticeable when the sinus cavities get infected by microbes such as virus, bacteria or certain chemicals. These factors cause inflammation and trigger the production of excessive mucus in the sinuses. Characteristic symptoms of sinusitis include:
- Pressure in the area around the sinuses
- Blocked or stuffy nose
- Loss of smell and taste
- Discharge of sputum
Usually, sinusitis does not need any medical intervention and goes away on its own. It is also advised to stay hydrated and get plenty of rest.
