Some areas overlying the implant can feel numb and take several weeks for full sensation to return. Implants can be made of a variety of materials, either a foreign material, other human tissue or your own tissue from other areas of your body. Most chin and cheek implants are plastic type materials that get integrated with the surrounding tissue and do well. Implants to the bridge of the nose are usually harvested from your own body such as within the nose or external ear. The risk of infection and rejection exist with all implants.
Most people take some antibiotics prophylactically to protect against infection.
Other complications include mobility and asymmetry. On occasion the implant can remain mobile while under the skin but this is usually not bothersome. When the implant twists or migrates to create asymmetry, it may require a revision procedure to place it back into its correct anatomic position.
