The incidence of lipomas is increasing and is receiving more attention. Why do lipomas grow? Too much food, too greasy; too much stress, irritability and endocrine disorders; bad habits such as staying up late at night are the main culprits. One of my patients had more than 30 lipomas all over her body and came to me every now and then to have 2-3 of them cut. This means that lipomas can cause discomfort, mainly pain or soreness when they are larger and press on the peripheral nerves. For lipomas that affect the quality of life, surgical removal is an option for both general surgery and plastic surgery, with plastic surgery focusing more on microscopy and scarring for those who are concerned about appearance. Most lipomas have an intact envelope and can be treated in one visit, but some have the potential for recurrence, so more fatty tissue can be removed during excision to help patients “slim down” for free? Lipomas have a very low malignancy rate, but need to be differentiated from malignant liposarcoma, which is usually not enveloped and poorly demarcated, and needs to be characterized by pathological examination. In this era where there is gradually no lack of food to eat, or material life is abundant, we hope that we can exercise more, live exquisitely, and keep our body and mind slim. At present, the mainstream nasal implants are silicone, expanded body and autologous cartilage, so I will talk about the characteristics and indications of these implants respectively, so that we can choose the materials scientifically and objectively. Advantages: low rejection rate, low infection rate, no deformation, easy to shape, can achieve the desired shape requirements, cheap, and once dissatisfied, can be removed intact, no residue. It is the main recommended material for nasal prosthesis at present. The reason why more and more clinics in the market now do not recommend silicone. Tumescent: a newer placement material than silicone, I’m sure you all know a lot of punch and shoes on the Geo-tex it, is a tumescent material. This material has its own characteristics, because the bentonite itself has many microporous, after implantation in the body, the surrounding normal tissue can grow into the material, so that the material and tissue will blend into one, touch more realistic. But its disadvantages come with it, first of all, the tissue will grow into the puffy hard, in addition, because there are many microporous, easy to harbor bacteria that lead to infection, making the infection rate higher; finally, once the shape is not satisfied or the occurrence of infection, as the tissue grows into the material, making the removal of the puffy becomes difficult, you must remove part of the self tissue. In addition, the biggest drawback is that expensive! But the tycoon must pad this can not be helped. Autologous cartilage: Now the hype on the market is the hottest when it comes to autologous cartilage rhinoplasty! All autologous tissue, this should be the best material, right? There is no mistake that autologous cartilage has been used in plastic surgery for a long time, and it has always been a principle in the field of plastic surgery to try to choose autologous tissue as implants. However, another principle of plastic surgery is the principle of less trauma, that is, for one type of surgery, try to use the simplest and least traumatic method. Therefore, for a long time, autologous cartilage, usually autologous rib cartilage, has been used in severe nasal deformities such as saddle nose deformity and nasal reconstruction. The reason is that this procedure involves the removal of the autologous tissue, creating a new trauma. To summarize, the advantages of autologous cartilage rhinoplasty: good tissue compatibility, no rejection; disadvantages: first, all the rib cartilage is removed, forming a new trauma, leaving a scar on the rib, second, the rib cartilage will be deformed after implantation in the body to a new location, third, the shape sculpture is limited by the size of the prosthesis.
