Inflammatory diseases of the sinuses:physiology. Clinical applications.

Physiologic principles form the foundation upon which rational medical and surgical decisions are based. Over the years, a growing understanding of the physiology of the nose and sinuses has evolved, allowing us to better treat our patients with sinonasal disease. As clinicians, we are challenged to keep abreast not only of advances in therapeutic options but also of advances in physiology. In this manner, we may employ the new therapies with both skill and intelligence.
