In the first group, the main risks are swelling, bruising, bleeding, infection, a scar and numbness or change in feeling. The main problems which are special for this operation are surface irregularity and the need for secondary surgery. In some patients fullness below the chin may not be due to fat alone. For example the hyoid bone, a small bone in the neck which acts as a starting point for some neck muscles, is anatomically placed low. In these cases the fullness of the neck will remain after surgery.
