There are several plastic surgery procedures that can be done on the nose, known as rhinoplasties available to correct various structural defects or to change the shape of the nose. Defects may be congenital, or result from nasal disorders or from trauma.
A bi-conic nose cone shape is simply a cone with length L 1 stacked on top of a frustum of a cone (commonly known as a conical transition section shape) with length L 2, where the base of the upper cone is equal in radius R 1 to the top radius of the smaller frustum with base radius R 2.
Rhinoplasty (Ancient Greek: ῥίς, romanized: rhī́s, nose + Ancient Greek: πλάσσειν, romanized: plássein, to shape), commonly called nose job, medically called nasal reconstruction, is a plastic surgery procedure for altering and reconstructing the nose.
There is heavy variation in the structure of the nasal bones, accounting for the differences in sizes and shapes of the nose seen across different people. Angles, shapes, and configurations of both the bone and cartilage are heavily varied between individuals.
The nasal cavity is divided in two by the vertical nasal septum. On the side of each nasal cavity are three horizontal outgrowths called nasal conchae (singular "concha") or turbinates. These turbinates disrupt the airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the septum.
The nasal cartilages are structures within the nose that provide form and support to the nasal cavity. The nasal cartilages are made up of a flexible material called hyaline cartilage (packed collagen) in the distal portion of the nose.
A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system.
The shape of the face is influenced by the bone-structure of the skull, and each face is unique through the anatomical variation present in the bones of the viscerocranium (and neurocranium). The bones involved in shaping the face are mainly the maxilla , mandible , nasal bone and zygomatic bone .
A nostril (or naris / ˈnɛərɪs /, pl.: nares / ˈnɛəriːz /) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities.
A perforated septum can vary in size and location, and is usually found deep inside the nose. It may be asymptomatic, or cause a variety of signs and symptoms. Small perforations can cause a whistling noise when breathing. Larger perforations usually have more severe symptoms.
