nasal septum

The nasal septum divides the nasal cavity into two parts of the left and right. It consists of bone, cartilage and mucous membranes. Lined with mucous membranes and skin. The nasal septum is divided into two left and right cavities, the front through the nostrils through the outside, the rear through the nasal hole through the throat. The nasal cavity on each side can be divided into a nasal vestibule and an intrinsic nasal cavity, which are bounded by a nasal valve. The nasal vestibule refers to an enlarged space surrounded by a nasal wing. The inner surface is lined with skin, has nasal hair, and has the function of retaining and adsorbing dust. The nasal septum is composed of the vertical plate of the ethmoid bone, the vomer and the septal cartilage, which are mostly biased to one side and are common to the left side. There are abundant vascular anastomoses in the anterior and posterior mucosa, and about 90% of nasal bleeding occurs here. It is clinically called the easy bleeding area, that is, the Little area or the Kiesselbach area.
