Acute sinusitis is more commonly known as a sinus infection. It occurs when the tissues that line the nasal passages and sinuses become inflamed. The common cold can cause it, environmental sources, or other nasal problems. Sinusitis makes breathing through the nose very difficult and several other unpleasant symptoms. Acute Sinusitis usually clears up on its own with home treatments. If the condition lasts longer than twelve weeks, it is chronic sinusitis.
The sinuses are a group of air-filled spaces within the skull that connect to the nasal passages and throat. There are four different sinuses located throughout the face. The maxillary sinuses are the largest and located in the cheekbone area. The frontal sinuses are in the forehead, the ethmoid sinuses are between the eyes, and the sphenoid sinuses are behind the nose. Healthy sinuses are made of healthy pink tissue and empty except for a thin layer of mucus. The sinuses main function is to help filter the air we breathe.
