Xiao Juan turns 10 this year. When she was very young, her parents worked in the fields and let Xiao Juan sleep at home. The mouse bit off her nose and scratched her face. Now that Xiao Juan has grown up and is sensible, he is often laughed at for his nose at school. When it is windy and rainy, Xiao Juan feels that the wind will blow directly into his throat, causing choking cough. Mom and Dad want to take Xiao Juan to the hospital and ask if they can rebuild a nose, but Xiao Juan has not fully grown up. The nose made now will not grow up with people in the future. What should I do? Nasal defects can be caused by congenital or acquired causes. Congenital partial or total nasal defects are rare or rare deformities; Acquired nasal defects are common, mostly caused by trauma, burns, frostbite, infection or tumor resection. A person with a serious nasal defect is not only damaged in appearance, but also prone to respiratory infection when cold wind blows into his throat in winter, and his voice will be affected because of poor nasal singing. Nasal defects can be divided into nasal dorsal scar contracture deformity, alar defect, nasal columella defect, nasal tip defect, half nasal defect and total nasal defect. Therefore, nasal reconstruction should also choose different repair methods for partial or total nasal reconstruction according to the characteristics of defects and deformities of different reasons, positions, structures and ranges. If the forehead skin is intact, the ideal repair method at present is to use expanded forehead flap for nasal reconstruction. Because nasal reconstruction is mostly repaired by skin flap and blood supply, the reconstructed nose can develop normally with the growth and development of the patient's body. Even in the case of Xiao Juan, plastic surgery is not suitable at present. This is because the trauma to nasal cartilage during operation will affect the growth and development of nasal cartilage. Even though the skin of the nose can develop and expand with the growth and development of the body, the growth and development of nasal cartilage will be affected after trauma. Therefore, Xiao Juan can cover his nostrils first, and then do nasal reconstruction after he is 16 or 17 years old and fully developed.
