What is “material rejection”? Why does it happen in some cases of nasal augmentation?
“Material rejection” is a the undesired expulsion of the implant from the operated nose which happens due to infection, irritation and daily trauma due to friction created by a hard implant like silicone. The nose with articulations in the lower and upper lateral cartilages is a dynamic structure which conforms to the force exerted by an external pressure up to certain point. With this nature, inserting a hard implant on the nose is like “placing a nail” on it which may eventually lead to material rejection.
