Background: Chin augmentation has been around for a very long time and many implant materials and sizes have been used to do it. From this experience has come standard implant sizes that work for the vast majority of people seeking chin enhancement surgery.
But some patients seek changes that exceed what these standard size can create or have discovered through prior surgery that their expectations have not been met. In these cases only a custom designed implant may suffice.
Case Study: This 35 year-old male had a prior history of multiple chin procedures including a square chin implant and a sliding genioplasty. While all of these procedure produced a better chin, they fell short of his ideal chin shape and size goal. Therefore a custom chin implant was designed that brought the chin forward 25mm and gave it a very square shape without having any lateral wings.
Under general anesthesia and through a existing submental incision the custom chin implant was placed over the end of the chin bone after removal of the indwelling implant. It was secured with a single 2.0mm titanium screw.
While custom chin implants can be made to any size and shape, it is important to consider how the soft tissue chin pad will drape over it. (or whether it will) While not all custom chin implants are of large dimensions, many are. The chin soft tissues will not adapt well with large amounts of spontaneous horizontal projection. This often causes tight tissues, lower lip stiffness and an abnormal appearance. It helps to have the chin soft tissues stretched out from prior chin augmentation procedures which is often the case before many patients seek a custom chin implant solution.
1) A custom chin implant is needed when the dimensions of standard chin implants can not create the desired effect.
2) An implant that provides significant horizontal projection with limited width requires a custom design.
3) Very large chin implants require previous soft tissue expansion from prior chin augmentation procedures.
