Compared with other surgical operations, cosmetic plastic surgery is less risky, but facial contour plastic surgery is relatively risky, and the most likely risks are facial artery trauma and massive bleeding. After massive bleeding, there are two situations that can lead to life-threatening, one is excessive blood loss, and the other is that blood flows into the trachea and causes suffocation. Since it is cosmetic surgery, it is inevitable to have a knife, and the operation will inevitably leave a knife edge. Trauma is one of the causes of vitiligo, because trauma will damage melanocytes and autonomic nervous system, hinder melanin synthesis and lead to leukoplakia. If cosmetic surgery is done, improper wound treatment can easily lead to infection, make vitiligo more serious or lead to vitiligo recurrence. If you must do it, it is recommended to communicate with the plastic surgery hospital before the operation to inform each other of your own situation and see if you can do it after comprehensive evaluation.
