The high forehead is mainly caused by the excessive arc of the frontal bone protruding forward. Most of them are congenital, but they can also be caused by the healing of fracture and dislocation of frontal bone after trauma. The appearance defect caused by mild frontal protrusion can be improved by several operations. Severe forehead protrusion is often accompanied by congenital or secondary craniomaxillofacial deformities, so forehead correction surgery is relatively complicated and needs to be decided according to the situation. The general forehead shaping method is to design a coronal incision at the hairline, cut the scalp, cap aponeurosis and periosteum under local anesthesia, peel forward to expose the frontal bone, and properly remove part of the cortical bone of the frontal bone according to the design before operation.
