A hump nose has a bulge in the bridge of the nose and is caused by overdevelopment of the bone or cartilage in the bridge of the nose, which is often congenital or can be related to nasal trauma. Humped nose does not usually affect the function of the nose but mainly affects the aesthetics, especially when viewed from the side. Before deciding to repair the nose, the nasal septum should be checked for curvature or deviation, and the nasal cavity and sinuses should be checked for infection, and these problems should be treated and the infection should be controlled before surgery. Three days before the operation, use anti-inflammatory liquid to drip the nose and trim the nose hair; measure the extent of the bridge of the nose that is too high, how much the tip of the nose that is too long needs to be shortened, and whether and how much of the cartilage of the tip of the nose needs to be excised and mark out the line of excision. Currently, the commonly used surgical method is the external nostril approach to hump rhinoplasty, because the internal nostril approach is more blind and relies heavily on experience to achieve success. Comparatively speaking, the external nostril incision can be anatomically separated under direct vision to observe the cause of the deformity and make the correct treatment; this surgical method does not cut the mucosa of the nasal cavity, which eliminates the trouble of suturing the nasal mucosa and the postoperative discomfort caused by stuffing the nasal cavity to the patient. The incision is made at the junction of the middle and lower 1/3 of the nasal columella, and the postoperative traces are not obvious. Modern cosmetic surgery has been nearly perfect for the correction of the hump nose. However, teenagers, people with systemic diseases, inflammation in the nose and unrealistic demands for surgical results should not undergo surgery. After surgery, the external nose needs to be fixed with adhesive tape and plaster bandage to promote the separated nasal skin to reapply with the skeleton to facilitate healing, and antibiotics should be applied to prevent infection. The stitches will be removed seven days after the operation, and you can gradually return to work after three weeks and review after three months.
