The nasal cavity includes the bones of the lateral nasal wall and the nasal septum. The lateral nasal wall includes the cribriform plate superiorly, the intricately swirled superior nasal concha (concha = “shell shaped,” to increase surface area for air circulation, warming, and decontamination; inferior to the sphenoethmoidal recess) and the middle nasal concha (inferior to the superior meatus) of the ethmoid bone. The lacrimal bone (a small fragile bone descending from the orbit) and the inferior nasal concha (inferior to the middle meatus and superior to the inferior meatus) are the other two bones populating the lateral nasal wall. Posteriorly, one can find the opening of the sphenoidal sinus, sphenoid body, medial plate of the pterygoid process of the sphenoid bone, the sphenopalatine foramen as described earlier, and the perpendicular plate and horizontal plate of the palatine bone (Plates 3.9 and 3.38). The vestibule (meaning, “the space between the entrance and the interior”) is anterior to the inferior meatus and the atrium (“open space”) is anterior to the inferior meatus. The position of nasal choanae (the caudal openings of the nasal passages) shifts caudally with the formation of the secondary palate.

Nasal cavity - on either side of the nasal septum (Fig.3.24), the roof of each half is only 1-2 mm wide, although the floor (the upper surface of the hard palate) is more than 1 cm wide. The lateral wall is the most complicated feature; its skeleton is made up of parts of the maxilla, the palatine and ethmoid bones and the inferior nasal concha (the superior and middle nasal conchae are part of the ethmoid bone).
Identification of bleeding sites and microwave thermal ablation of posterior epistaxis

We identified the most common bleeding sites associated with posterior epistaxis: the septal region of the medial wall of the middle nasal concha, the middle meatus, the fornix of the inferior meatus, and the posterior lateral wall of the inferior nasal concha. Most of bleeding point showed the hemangioma of nasal mucosa in the patients with posterior epistaxis. MWA is a minimally invasive therapeutic technique, which may effectively control the bleeding with a low cost and without complications. However, whether prophylactic MWA was necessary should be further studied for the patients with unknown bleeding in future.
