Causes and Evaluation of Acute Sinusitis

New York (USA), June 27, 2013

Causes of Acute Sinusitis

Causes for acute sinusitis include:

Common Cold: This viral infection is the predominant cause.

Fungal Infection: A weak immune system or sinus abnormalities cannot fight off fungal infections leading to acute sinusitis.

Allergies: Hay fever inflames your sinus and causes blockages in nasal tract.

Bacterial Infection: Bacteria are responsible for infection in upper respiratory tract. Persistent infection for seven to ten days causes acute sinusitis.

Adenoids: These are located in upper back part of throat. Infection or enlargement of adenoids causes sinusitis.

Structural Deformities: Nasal bone spur, deviated nasal septum (wall between nostrils), or nasal polyps block opening of sinuses.

Smoking: Cigarette smoke or smoke from chemicals aggravate sinus region leading to sinusitis.

Auditory Tube: Eustachian or auditory tube is connected to sinus cavities through your throat. This tube is normally on same level as your eye sockets. Sometimes tube is at a lower level or at same level as nasal entrance due to hereditary abnormalities. This causes blockage and subsequent infection within sinus cavities leading to sinusitis.

Evaluation of Acute Sinusitis

Sinuses are air-filled spaces located in your skull like nasal bones, behind forehead, cheeks, and eyes. Normally, they do not contain any germs or bacteria. Mucus drains out normally and air circulates freely. However, when sinus is blocked, mucus accumulates. Germs and bacteria thrive. This leads to acute sinusitis.
