Early detection of nasal tip swelling after operation is sometimes the cause of nasal congestion. If it doesn't improve after several days of observation, the prosthesis should be taken out as soon as possible until the skin is obviously congested, purple-black or broken. Taking it out at this time will damage the shape of the tip of the nose or leave a scar. Even if the prosthesis is removed before the skin is damaged, it is not appropriate to implant the prosthesis immediately. It should be observed for 3 months, and then consider whether it can be implanted again according to the situation.
