It is concluded that the reduction method of bridge of nose fracture is a method to restore the broken and collapsed bridge of nose to its original position, so as to correct the deformity and keep breathing smooth.
3. Patients with nasal bridge fracture and collapse deformity during operation should be reset as soon as possible. If it is difficult to reset due to severe nasal swelling, it can also be delayed for a few days until the swelling subsides. However, it should not be too late. After more than two weeks, too many callus forms or malposition heals, which is not easy to recover.
Operation method After cleaning the nasal cavity, anesthetize the nasal mucosa with 2% tetracaine and 1‰ adrenaline solution for 5 minutes. When necessary, children can take general anesthesia.
Use nasal bone reduction forceps or appropriate surgical handle, put on latex tube, put it under the collapsed nasal bone, and gently lift the nasal bone upward and outward. At the same time, the index finger and thumb of the other hand can press on the bridge of the nose to assist in the reduction, so that it is symmetrical with the healthy nasal bone.

If bilateral nasal bones collapse, they can be reset from both nasal cavities at the same time. (Note that after the reduction instrument is inserted into the nasal cavity, it should not exceed the line connecting the corners of the eyes, so as not to damage the sieve plate. If the nasal septum is fractured and dislocated, you can also use the reduction forceps to reach into the nasal cavity to hold the nasal septum and straighten its position.
After reduction, the nasal cavity was filled with sterilized vaseline gauze and kept for 24 ~ 48 hours to achieve the purpose of fixing the fracture and compressing hemostasis. If necessary, put a saddle-shaped white aluminum splint on the nose, cover it on the bridge of the nose and stick it with adhesive tape for protection.
