And what are its shortcomings? Now we will invite experts from Dalian Dongping Plastic Surgery Hospital to introduce you. Korean injection rhinoplasty is an early rhinoplasty method, which uses liquid silica gel, but in recent years, there are also methods of injecting artificial bone powder or other artificial materials. The advantage of Korean injection rhinoplasty is that it doesn't even need anesthesia. Injecting a needle and shaping at the same time can be completed in a few minutes, and the patient can hardly feel pain. However, Korean injection rhinoplasty has the following disadvantages: 1. Korean injection of artificial materials such as silicone rubber rhinoplasty is easy to cause tissue reaction and difficult to take out, so the silicone rubber flow after Korean injection of rhinoplasty is easy to cause deformity, and the silicone rubber is closely attached to the tissue, which is difficult to separate and repair. 2. After Korean-style injection rhinoplasty, the patient's skin turns gray or the skin reflectivity is enhanced, which may be related to the incomplete vulcanization of silicone rubber, or it may be that Korean-style injection rhinoplasty has penetrated into the surrounding tissues because it is too deep or too shallow. 3. At present, there have been reports about silicone rubber caused by rhinoplasty with liquid silicone rubber injected by Koreans. Animal experiments show that there is no rejection reaction in the tissues around the coalesced silicone rubber, but there is always a giant cell reaction around the silicon particles. 4. The method of injecting rhinoplasty in Korea is incorrect (if the injection is too shallow). Some patients have skin fistula, and in severe cases, skin necrosis, local ulceration, perennial unhealed. Korean injection of liquid silicone rubber is needed to remove the infiltrated tissues in rhinoplasty. If the wound is small, it can be closed in one stage, and the area of wound ulceration is large. Korean injection rhinoplasty needs skin flap or free skin graft to repair it.
