Sinuses are empty spaces in the facial bones and forehead bones. They contain air and are lined with the same mucus membrane that lines the nasal passages. They connect with the nose passage through small openings called Ostia. Typically these Ostia are 1-2 mm in size and are the only means of clearing the sinuses into the nasal passage. The mucous membranes make mucus and kept the cavities moist and have small cilia or hair lining the mucus membranes that beat towards the openings.


Sinusitis is a term used for inflammation of the sinus mucus membranes. Inflammation may be caused by infection, allergies, smoke, pollution, bacteria, fungi, or viruses. Some conditions such as HIV, immune deficiencies, or connective tissue diseases such as sarcoidosis, Wegener’s granulomatosis, or ciliary problems make it more likely to have sinus inflammation.
