All operations are risky. For example, rhinoplasty, intraoperative infection or improper operation may lead to runny nose and poor ventilation. And patients with rhinitis can't have rhinoplasty. Eyes may vary in size, and the opening in the inner corner of the eye may leave a scar. At that time, the dean also said that this kind of canthus scar was possible and could not guarantee 100% perfection. It depends on luck. The outer corner will grow back after a long time. Therefore, to find a better regular plastic surgery hospital, ask clearly first. My cousin and I have both done it, but the price is a bit expensive.
