1.What are the dangers of Omniderm? Over a decade ago, Omnidene was used as “artificial fat” in various parts, such as breast, face, etc. With the passage of time, various complications came, such as infection, fibroplasia, wandering the whole body, local swelling, cancer and so on. 2.Should I take it out? In view of the above hazards, it is generally recommended to take it out. If the imaging shows that the injection is wrapped by the surrounding tissue and the individual has no psychological burden, close clinical observation can be considered. 3.Can it be taken out completely? If the injection is single-site or single-level single-point injection, it is relatively easy to take out if it is wrapped by the surrounding tissues after the operation, but if it is multi-level or multi-site injection, it is difficult to take out if it is diffused to the surrounding tissues after the operation. It is difficult to take it out completely. Detailed preoperative MRI and ultrasound examination will clarify the specific site and make the removal more thorough.
