To understand sinus disease, it is important to first learn about your sinuses and their role in your health.
The sinuses are air spaces behind the bones of the upper face, between the eyes and behind the forehead, nose and cheeks. They are covered with mucus layers and cilia, which help trap foreign objects and clear them from the sinuses.
Each sinus has an opening that allows mucus to drain – this drainage is essential for maintenance of sinus function and health. Any obstruction of sinus openings may cause mucus buildup in the sinuses and trigger mild to severe symptoms.
Healthy sinuses are key to quality of life; unhealthy sinuses may cause discomfort and significant health complications.
