What is a crooked nose? What are the classifications of rhinorrhea? Han Hou Han Hou plastic surgery experts said that crooked nose means that the position of the bridge of the nose deviates from the central axis, that is, the central line of the back of the nose is not in the middle of the face. Can crooked nose affect the function of nose? What are the different types of performances? The distortion of the bridge of the nose (bending to both sides) has aesthetic problems, but it also has the problem of functional nostril blockage. Because the nasal septum in the nose divides the nasal cavity into two parts, when the nose bends, the nasal septum will also bend. When the nasal septum is biased to one side, it will block the nostril on that side, while the opposite side will be relatively widened, and the airflow will generate a vortex, which will hinder the normal airflow. Too much nasal deviation is caused by improper handling of nasal trauma. The nose protrudes forward more than other structures on the face, so it is vulnerable to trauma. Generally speaking, there are the following types of crooked nose: 1, C type: This type is characterized by the fact that the root and tip of the nose are located on the axis, and the middle part of the bridge of the nose is bent into a C shape far from the central axis. 2. Deviation type: this type is also called simple deviation nose, which is defined as deviation of nasal cartilage, that is, the lower part of the nose, and may also be accompanied by slight deviation of nasal bone. It is characterized in that the middle and lower part of the bridge of the nose deviates to one side of the central axis, and the tip of the nose is farthest from the central axis. Most of them are caused by congenital or childhood trauma. 3.S type: This type is also called complex crooked nose, and the cartilage and bone cone of the nose bend in different directions in an S shape.
