The nose is made of many types of tissue, which makes rhinoplasty especially difficult for the untrained surgeon. The nasal framework consists primarily of cartilage, which forms the lower two-thirds of the nose and the anterior septum. Complexity is created by the many individual pieces of cartilage, their unique shapes, and the strong connective tissue that holds them together. Bone is also important, forming the upper one-third of the nose and posterior septum. The nose also has the pink, moist tissue on the inside – the “mucosa” – and several small muscles that affect its shape. Most, if not all, of these tissues need to be altered during a rhinoplasty surgery, so the skin will lay down over them in consistent manner, and the nasal appearance and function will improve.
