Your sinuses are empty air-filled chambers within the bones of the face. When they work well, the sinuses constantly clean themselves with a thin coating of mucus. This mucus lubricates your nose and keeps it free of dust and bacteria. This drainage system can shut down when an underlying problem, such as colds, allergies, or an obstruction causes blockages. The hallmark of sinusitis is facial pain, purulent nasal drainage, and/or nasal congestion. Additional symptoms may include headaches, bad breath, chronic fatigue, post nasal drainage, and diminished sense of smell.

If symptoms are not cleared by medical therapy and become chronic in nature, a thorough evaluation by an otolaryngologist may be necessary to uncover the cause and extent of your sinus disease. This entails a comprehensive history of your sinus problems as well as a physical examination. A computed tomographic (CT) scan of your sinuses may also help aid in the evaluation of your disease. Depending on the results of your evaluation, you may be a candidate for endoscopic sinus surgery.
