Genioplasty surgery is a more complex, aggressive surgery than placing a silicone chin implant because it involves cutting and repositioning the jawbone. Because of that, it's more expensive and comes with some additional risks.
Chin implants can be placed through the mouth or through an incision under the chin.Â
During a sliding genioplasty, cuts (osteotomies) are made to the bone, which is then moved forward and held in place with titanium screws. For patients who feel their chin is too big, the bone is moved backward.Â
In the U.S., plastic surgeons tend to recommend chin implants more often, while oral surgeons tend to recommend a sliding genioplasty (aka osseous genioplasty). Consider consulting with surgeons who perform both techniques. A sliding genioplasty is often not offered to patients by doctors who are inexperienced in the procedure. âItâs a technically more difficult procedure, but when done correctly it can provide natural and long-lasting improvement in your chin,â says Dr. Jamali.
Both procedures have advantages and disadvantages.Â
These are the primary benefits of a chin implant:
- Chin implants are manufactured in a variety of shapes, sizes, and projections to customize your look. âThey are much better than the old button-type implants that gave chin implants a bad name for many years,â says Dr. James McMahan, a plastic surgeon in Columbus, Ohio. You and your surgeon will determine which implant is best for you based on your goals.Â
- Chin implants are usually made of solid medical-grade silicone and have a long history of safe use.
- The average cost of a chin implant is significantly less than a genioplasty procedure.
- When placed in the correct position, the implant looks and feels natural.
- The complication rate is very low.
- The implant can be removed, replaced, or repositioned if need be.
However, there are potential drawbacks:
- This surgery can leave a scar, though itâs usually small and placed under the chin.Â
- If the wrong implant size or shape is chosen, it can look unnatural.
- An implant can cause some jawbone erosion. Over time, the implant can sink into the bone and lose its projection. If this happens, the implant can be removed relatively easily and replaced with a new, larger implant.Â
A sliding genioplasty has several advantages over a chin implant:
- It doesnât require the use of a prosthesis. âThe patientâs own bone is used, so the result looks and feels natural,â says Dr. Jamali.
- By repositioning your chin bone, itâs capable of a wider array of dimensional changes than a chin implant. The procedure is more versatile and can correct a broader range of concerns, including a large chin (macrogenia), a small chin (microgenia), and an asymmetrical chin.Â
- Itâs the procedure of choice if your chin needs to be moved forward and vertically shortened, something an implant just canât do.Â
- A sliding genioplasty can also correct lip incompetence, the inability to keep your lips together without straining.Â
- It wonât leave a visible scar.
- Recovery is relatively quick. Though the bone takes 3â4 months to fully heal, 50% of the swelling disappears after a week. âAt that point, people usually can enter back into their daily lives without any notice that a procedure was done,â says Dr. Jamali.Â
- It's generally a better procedure for people who have a severely receding chin (aka weak chin), when the chin slopes back toward the neck, according to doctors on RealSelf. âIn cases that require more than 5 mm of projection, I prefer to perform a genioplasty,â says Dr. Michael Morrissette, an oral and maxillofacial surgeon in Ventura, California. âThe results of genioplasty are precise and the benefit is that the natural chin and chin pad soft tissue is moved forward. I think it gives the most natural results and I perform both chin implants and genioplasty.âÂ
- The procedure is relatively low-risk. âThe most significant risk is sensory nerve dysfunction or loss of feeling in the chin,â says Dr. Morrissette. âThis can mostly be avoided with an experienced surgeon and protection of the nerve bundle during surgery.âÂ
There are some cons to a sliding genioplasty:
- Itâs a more extensive procedure that comes with a higher cost.
- The procedure is performed under intravenous or general anesthesia (one of the reasons it's more expensive). Â
- Thereâs a greater risk of permanent lip numbness, though this is still rare.Â
- âInferior border notching,â which looks like two small grooves on either side of your chin, often occurs after a sliding genioplasty. The larger the bone movement, the more likely it will occur. But there are ways to lessen it, such as a low-angled cut, or filling in the notch with fat grafts or fillers.Â
An experienced surgeon who regularly performs both types of chin surgery can help you weigh both options and recommend the best procedure for your facial anatomy, goals, and budget.
RealSelf Tip: If youâre not ready to commit to surgery, temporary chin fillers can allow you to âtry onâ chin augmentation.
