The primary difference between male and female facial contours lies in the width of the cheekbone or mandible and the thickness of bones. As the male face is relatively more prominent and angular and has a wider and more expanded frontal area than the female face, it appears square, greatly different from the female oval face. Therefore, male-to-female facial conversion should highlight the softening of skeletal contour lines, and patients generally have to undergo several facial bone reductions to fulfill the traditional cognition about females; this change is also called composite facial bone remodeling. The concrete contents and scope are determined based on the patient’s original conditions and requirements, commonly including cheekbone reduction, mandible reduction, or V-shape chin osteotomy (genioplasty) to achieve a complete face change. Compared with common female bone reduction, this reduction is almost the same but has to reduce more in bone width and thickness and is usually conducted along with multiple bone reductions or other plastic surgeries like double eyelid surgery, augmentation rhinoplasty, or lip reduction. Therefore, the surgical duration is relatively long, and the change in the proportion of the overall facial contour by each surgery should be accurately calculated by the physician to attain a new facial contour characteristic to females.
