Endoscopic anatomy of the nose and sinuses
It is required that all paranasal sinus surgeons have a clear understanding of the anatomy of the region that they are going to operate on. An endoscopic, endonasal visualization first sees the inferior, middle and superior turbinate, all of which insert into the lateral nasal wall. Occasionally the supreme turbinate may be seen. Below and laterally to each of these is their corresponding meatus. The inferior nasal meatus runs practically in an anteroposterior trajectory above the nasal floor, and below the inferior turbinate until it reaches the choanae (Fig. 1).
