![]() ![]() ![]() The minor alar cartilages vary in number, there are usually 3 or 4 on each side. The lateral and major alar cartilages are the largest, and contribute the most to the shape of the nose here. The inferior portion of the external nose is made up of hyaline cartilages lateral, major alar, minor alar, and the cartilaginous septum. It is partly formed by the nasal and maxillary bones, which are situated superiorly. The external skeleton extends the nasal cavities onto the front of the face (see Figure 1). When looking at the scaffolding of the nose, it is useful to divide the structures into two parts the external nasal skeleton and internal nasal septum. The skeleton of the nose is formed by three types of tissue bone, cartilage and fibro-fatty tissue. Here we will discuss the anatomy of the nasal skeleton and its component bones. 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. The cribriform plate of the ethmoid bone forms the roof of the nasal cavity. The hard palate consists of the palatine bone posteriorly, and the palatine process of the maxilla anteriorly. The floor of the nasal cavity is formed by the hard palate, separating it from the oral cavity. ![]() CORRECTION Narrow the tip of the nose and widen the bridge of the nose (between the eyes). PROBLEM This results in an out-of-balance appearance. The anterior and posterior parts are formed by the septal cartilage and vomer bone respectively. The triangular nose is narrow at the bridge area (between the eyes) and wider at the tip. It is one of the most complex bones in the human body, and its structure is beyond the scope of this article, however more information can be found here. The ethmoid contributes to the central portion of nasal septum. In addition to the bones of the nose, the septal and greater alar cartilages also constitute part of the nasal septum. Unpaired bones: Ethmoid and vomer bones.Paired bones: Nasal, maxillary and palatine bones.The bones that contribute to the nasal septum can be divided into: The internal nasal septum separates the nasal cavity into two nostrils.
