Genioplasty vs chin implant. Which will make my face more chiseled and masculine? (photo included)

A genioplasty will absolutely improve your chin and profile, and will also add some definition to your jawline. A chin implant will add some advancement, but will not do much for the jawline. A genioplasty will allow for movement of the chin segment forward and down, creating more definition and masculine features. A chin implant can be placed later on, although a genioplasty done properly should not need anything added afterwards.

For your chin you need both horizontal and vertical lengthening which can be done by either a sliding genioplasty or a custom chin implant. If you are worried about potential nerve damage than the custom chin implant would be the preferred method. The jawline is only going to become more masculine/ defined by jaw angle implants which can be done later if desired or you may consider going for the entire jawline augmentation at once with a custom wrap around implant.

A genioplasty is performed by an oral surgeon under general anesthesia in a hospital setting with an overnight stay, and is much more invasive. It is usually performed when the teeth are significantly out of alignment. Placement of a chin implant can be performed under local anesthesia, and is much less invasive. Chin implants simply augment the current bony mandible that you currently have. Liposuction in the neck would be helpful to get more definition of the jawline.
