Genioplasty is a surgical procedure that reshapes the chin by cutting and repositioning the chin bone. Unlike a chin implant, which places a synthetic material over the existing bone, genioplasty changes the structure of the bone itself. It can move the chin forward, backward, up, down, or side to side, making it one of the most versatile options for correcting chin shape and position.
How It Differs From a Chin Implant
The two most common approaches to chin enhancement are genioplasty and chin implants, and they work in fundamentally different ways. A chin implant involves inserting a silicone-based prosthetic into a pocket created beneath the skin and securing it with sutures. The bone stays untouched. Genioplasty, by contrast, uses a specialized saw to cut the chin bone, reposition it, and lock it into place with small titanium plates and screws.
This distinction matters for a few reasons. Implants can only add projection. They sit on top of the bone and push the chin forward, but they can’t raise it, lower it, or correct asymmetry. A sliding genioplasty (the most common type) can move the chin segment in any direction, which makes it the better option for complex corrections. The results are also permanent in a different way: because the bone heals in its new position, there’s no implant that could shift, erode into the bone over time, or need replacement.
Why People Get Genioplasty
Most genioplasty patients have a chin that sits too far back relative to the rest of their face, a condition sometimes called chin recession or retrogenia. This can make the nose appear larger, the neck less defined, and the profile unbalanced. But the procedure addresses more than just a weak chin. Surgeons also perform it to correct a chin that’s too long vertically, too short, or tilted to one side. In some cases, genioplasty is done alongside jaw surgery to treat functional problems like bite misalignment.
What Happens During Surgery
Genioplasty is performed through an incision inside the mouth, along the lower lip area. There’s no visible scar on the face. The surgeon makes a cut roughly 3 centimeters long in the tissue lining the lower gum, then carefully exposes the chin bone while preserving the nerves that provide sensation to the lower lip and chin.
The bone cut (osteotomy) is made below the roots of the teeth and below the nerve openings in the jawbone. The surgeon separates a horseshoe-shaped segment of the chin bone, then slides it into the planned position. If the chin needs more projection, the segment moves forward. If it’s too long, a strip of bone can be removed before repositioning. Once the segment is where it needs to be, the surgeon fixes it with titanium plates that stay in place permanently.
The procedure can be done under general anesthesia or, in some cases, under local anesthesia with sedation. Using local anesthesia with sedation can reduce costs and overall surgical complexity, though general anesthesia remains common for more involved cases.
Recovery Timeline
Recovery from a sliding genioplasty takes several weeks in total, but most of the downtime is concentrated in the first 10 days. Swelling and bruising typically last up to two weeks, with the worst of it in the first few days. Dressings come off around day three or four, and stitches dissolve on their own over the following weeks. Most people return to work and normal activities, including exercise, within seven to 10 days.
Diet is a significant part of recovery. You’ll start with liquids for the first several weeks, then transition to soft foods that don’t require chewing. Hard or crunchy foods are off limits until your surgeon confirms the bone has healed enough to handle the stress. Eating solid food too early risks re-fracturing the healing bone, which would require additional surgery and a longer recovery.
For the first 24 to 48 hours, ice packs help control swelling. After that, switching to heat is typically recommended. Keeping your head elevated while sleeping and maintaining careful oral hygiene around the incision site also help the healing process.
Risks and Nerve Sensation
The most talked-about risk of genioplasty is numbness in the lower lip and chin. The mental nerve, which provides sensation to that area, runs close to where the bone is cut. Some degree of temporary numbness after surgery is common and expected. For mandibular procedures broadly, studies report sensory changes in roughly 35% of patients at six months, with rates staying similar at one and two years out. The risk of permanent numbness varies widely depending on the complexity of the surgery and the surgeon’s technique, but careful nerve identification during the procedure significantly reduces it.
Other potential complications include infection, poor bone healing, and asymmetry. In long-term studies of genioplasty specifically, researchers have reported no cases of malunion (bone healing in the wrong position), non-union (bone failing to heal), or hardware failure, which speaks to the general reliability of the procedure when performed with proper fixation.
Long-Term Results and Stability
Genioplasty results are permanent. Once the bone heals in its new position, it stays there. Research tracking patients for two years after advancement genioplasty found a relapse rate of just 1% of the total surgical movement, meaning the chin held almost exactly where the surgeon placed it. Most of the minor settling that does occur happens in the first six months. Changes after that point are negligible.
The bone does remodel over time, which is normal and expected. Sharp edges left by the bone cut smooth out naturally, and the body deposits new bone along the surfaces of the repositioned segment. This remodeling doesn’t change the overall chin position or shape in any meaningful way. It simply means the bone matures and integrates into its new location.
Cost
The average surgeon’s fee for chin surgery is $3,641, according to the American Society of Plastic Surgeons. That number covers only the surgeon’s time. Anesthesia, operating room fees, imaging, and any pre-surgical planning (such as 3D-printed surgical guides) add to the total, often pushing the all-in cost significantly higher. Most health insurance plans do not cover genioplasty when it’s performed for cosmetic reasons. Coverage is more likely when the procedure is part of a medically necessary jaw reconstruction. Many surgeons offer financing plans to spread the cost over time.
