Document Summary

The nasal skeleton is a combination of bone and cartilage which forms both what we can see as the external nose and the internal nasal septum which divides the two nasal cavities of the head. Here we will discuss the anatomy of the nasal skeleton and its component bones. The skeleton of the nose is formed by three types of tissue; bone, cartilage and fibro- fatty tissue. When looking at the sca olding of the nose, it is useful to divide the structures into two parts; the external nasal skeleton and internal nasal septum. Figure 1 lateral view of the external nasal skeleton. The external skeleton extends the nasal cavities onto the front of the face (see figure. It is partly formed by the nasal and maxillary bones, which are situated superiorly. The inferior portion of the nose is made up of hyaline cartilages; lateral, major alar, minor alar, and the cartilaginous septum.
