Forehead depressions can be divided into hemifacial depressions and central depressions. Hemifacial forehead depression, i.e., the depression occurs only on one side of the forehead. Due to the special anatomy of the forehead, hemifacial depression may be accompanied by depressions in the eyelid, cheek and up to the entire half of the face, which may be caused by congenital genetics or dysplasia, or by trauma and infection. Secondary atrophic depression is a common form of hemifacial forehead depression, and the repair of hemifacial forehead depression can be done by plastic surgery, i.e., by means of prosthetic implant filling after the atrophy has stopped. Prosthesis can choose autologous rib cartilage, dermal fat graft, silicone film, expansion, etc., of which autologous cartilage is the most ideal. For forehead median depression that is the forehead median area depression, this kind of depression is mostly congenital, may even forehead bone also have depression. Most of the forehead median depressions are congenital, and most of them have stopped progressing when they are found later in life. The depressions can be filled by making skin incisions with “W” molding and implanting autologous cartilage, dermis, fat and silicone rubber.
