Facial injections are a popular minimally invasive plastic surgery technique with no surgical incisions, minimal trauma, and quick recovery, and are easily accepted by a wide range of patients. However, there are a lot of unsafe injectables on the market, including Omnidene, bone powder, microcrystalline porcelain and so on. Many patients injected with illegal products in illegal institutions often have complications such as local hard nodules, redness, swelling and pain, which cause facial deformity and require removal of the injected materials. The traditional incision to remove the foreign body is not only obvious, but also not easy to distinguish the foreign body from the normal tissue during the operation, which is more traumatic. For a small amount of foreign body injection, there is no need to overemphasize complete removal. Swelling anesthesia can be used to remove most of the foreign body, which can serve the purpose of restoring the local shape and preventing systemic complications. Some patients with foreign body injections are very nervous. They want to remove it as soon as possible and take it out completely! In essence, a small amount of foreign body will not cause systemic effects, and the small amount of foreign body remaining will not seriously affect the appearance. Since the foreign body has been injected, you should relax your mind and not worry too much, sometimes the psychological stress is much greater than the damage of the foreign body!
