Chin Augmentation
Also known as genioplasty or mentoplasty
Chin augmentation is a surgical procedure that enhances the projection, shape, or size of the chin to improve facial balance and profile harmony. The procedure can be accomplished through the placement of a solid silicone or other biocompatible implant (alloplastic augmentation), or through sliding genioplasty, a technique that repositions the patient's own chin bone [1]. Chin augmentation is one of the most effective procedures for improving facial proportions, as the chin plays a critical role in defining the lower third of the face and the profile silhouette.
The procedure is frequently performed in conjunction with rhinoplasty, as the relationship between the nose and chin significantly influences perceived facial balance [1]. A receding or weak chin can make the nose appear larger, and correcting the chin projection can enhance the overall result of nasal surgery. According to the American Society of Plastic Surgeons, chin augmentation is a consistently popular procedure, with approximately 5,500 performed annually by ASPS member surgeons in the United States [1].
Overview
Chin deficiency, whether presenting as microgenia (a small chin) or retrognathia (a posteriorly positioned mandible), is a common aesthetic concern that affects the balance and harmony of the face. When the chin is underprojected relative to the nose and forehead, the face can appear bottom-heavy, the neck may lack definition, and the profile silhouette may be perceived as weak or unbalanced. Chin augmentation corrects these proportional issues by bringing the chin into harmony with the rest of the facial features.
The concept of facial balance has been studied extensively in aesthetic surgery. Classical proportions divide the face into three equal vertical thirds: hairline to brow, brow to nasal base, and nasal base to chin [1]. When the lower third is deficient due to chin retrusion, the overall facial balance is disrupted. Chin augmentation restores this balance by adding projection, width, or vertical height to the chin as needed.
Two primary surgical approaches exist. Chin implant surgery places a preformed or custom implant over the existing chin bone to add projection and contour. Sliding genioplasty involves cutting the chin bone, moving it forward (or in other directions), and securing it with titanium plates and screws. Each approach has specific advantages. Implants are simpler, faster, and reversible, while sliding genioplasty offers more versatile three-dimensional movement and uses the patient's own bone, eliminating implant-related complications.
Chin augmentation is frequently combined with other facial procedures. Rhinoplasty is the most common companion procedure, and the combination is sometimes referred to as profiloplasty. Neck liposuction or submental liposuction can enhance chin definition by removing submental fat. Facelift and neck lift procedures may incorporate chin augmentation to optimize jawline contour.
Techniques & Approaches
Chin implant surgery is the most commonly performed chin augmentation technique. Implants are available in various sizes and shapes, including anatomic (conforming to chin contour), extended (wrapping along the jawline), and custom-fabricated designs for complex corrections. Solid silicone is the most widely used implant material due to its biocompatibility, ease of placement, and removability [1]. Other materials include porous polyethylene (Medpor) and polyetheretherketone (PEEK).
The implant can be placed through either an intraoral incision (inside the lower lip) or a submental incision (beneath the chin). The intraoral approach leaves no visible scar but carries a slightly higher risk of implant infection due to exposure to oral bacteria [1]. The submental approach produces a small scar in the natural chin crease that typically heals inconspicuously. Through either approach, a pocket is created directly over the chin bone, and the implant is secured in position with screws or sutures.
Sliding genioplasty is a more complex procedure that involves making a horizontal cut (osteotomy) through the chin bone below the tooth roots. The freed chin segment is then advanced, set back, moved vertically, or rotated to achieve the desired change and fixed in its new position with titanium plates and screws. This technique offers three-dimensional control over chin position and is preferred for patients requiring significant advancement (greater than 8 to 10 millimeters), vertical lengthening or shortening, or correction of chin asymmetry [1].
Who Is a Good Candidate?
Ideal Candidates
Ideal candidates for chin augmentation are adults with a receding, weak, or underprojected chin that creates facial imbalance. The procedure is appropriate for patients who desire improvement in their profile, jawline definition, or overall facial proportions. Candidates should be in good general health, have a stable bite (occlusion), and have realistic expectations. Chin augmentation is suitable for both men and women, though the aesthetic goals may differ, with men typically desiring a stronger, more angular chin and women preferring a softer, more tapered contour.
Not Suitable For
Chin augmentation may not be appropriate for patients with significant malocclusion or skeletal jaw discrepancy that requires orthognathic surgery. Active dental infections or periodontal disease, particularly when the intraoral approach is planned, increase the risk of implant contamination. Patients with autoimmune disorders or conditions that affect bone healing may not be ideal candidates for sliding genioplasty. Those with unrealistic expectations about the degree of facial transformation achievable through chin augmentation alone should be counseled about the limitations of the procedure.
Risks & Benefits
Benefits
Chin augmentation is one of the most impactful procedures for improving facial harmony relative to its simplicity and recovery time. By bringing the chin into better proportion with the nose, forehead, and jawline, the procedure creates a more balanced and aesthetically pleasing facial profile. The improvement is often described as transformative by patients, who note that their entire face appears more harmonious.
For patients undergoing rhinoplasty, chin augmentation can enhance the perceived result by improving the nose-chin relationship, sometimes reducing the degree of nasal modification needed. The procedure can also improve the appearance of a double chin by increasing anterior projection and creating a sharper cervicomental angle. Both implant and genioplasty approaches produce permanent results, eliminating the need for ongoing maintenance treatments.
Risks & Considerations
Risks of chin implant surgery include bleeding, infection, numbness of the lower lip and chin (due to injury to the mental nerve), implant displacement or asymmetry, and bone erosion beneath the implant over time. Implant infection, while uncommon, may require implant removal. Bone erosion is typically minimal and clinically insignificant but can be detected on imaging studies in some long-term follow-up cases [1].
Sliding genioplasty carries additional risks related to bone surgery, including non-union (failure of the bone to heal), damage to tooth roots, and palpable or visible hardware (plates and screws). Numbness of the lower lip and chin occurs more frequently with genioplasty than with implant surgery but is usually temporary, resolving over weeks to months [1]. Both procedures carry a risk of asymmetry, overcorrection, or undercorrection that may require revision surgery. Overall complication rates for chin augmentation are low when performed by experienced surgeons.
Alternative Procedures
Non-surgical chin augmentation using injectable dermal fillers, typically calcium hydroxylapatite (Radiesse) or hyaluronic acid products, can provide temporary chin enhancement without surgery. Fillers add projection and can refine chin shape, with results lasting 12 to 24 months depending on the product used [1]. Non-surgical augmentation is appropriate for patients desiring modest enhancement, those who want to preview surgical results, or individuals who prefer to avoid surgery. However, fillers cannot achieve the degree of augmentation possible with implants or genioplasty, and they require ongoing maintenance treatments.
For patients with significant jaw discrepancy (malocclusion) that affects bite function, orthognathic surgery (jaw surgery) performed by an oral and maxillofacial surgeon may be more appropriate than isolated chin augmentation. Orthodontic treatment may be a component of the overall correction plan.
Preparation & Recovery
Pre-Surgery Preparation
Preparation for chin augmentation includes a thorough facial analysis, including assessment of chin position, bite relationship, and facial proportions. Imaging studies, including lateral cephalometric radiographs or CT scans, may be obtained to evaluate bone anatomy and plan implant size or genioplasty movements. The surgeon and patient review photographs and may use computer imaging to preview potential results.
Blood-thinning medications and supplements should be discontinued at least two weeks before surgery. For the intraoral approach, patients may be instructed to use an antimicrobial mouth rinse in the days before surgery. Patients should arrange for transportation home and plan for a soft diet during the initial recovery period.
Post-Surgery Care
After chin implant surgery, a chin dressing or compression garment may be applied to minimize swelling and support the implant during initial healing. For the intraoral approach, patients are instructed to rinse with an antimicrobial mouthwash after meals. A soft diet is recommended for the first one to two weeks to minimize stress on the incision and surrounding tissues.
Patients should sleep with their head elevated for the first week to reduce swelling. Strenuous physical activity should be avoided for three to four weeks. Contact sports and activities that risk chin trauma should be avoided for at least six weeks. Numbness of the lower lip and chin is common in the early postoperative period and typically resolves within weeks to a few months. Follow-up appointments are scheduled at one week, one month, and three months to monitor healing and implant position.

3-5 days
Swelling peaks then begins to subside, soft diet continues
1 week
Sutures removed or dissolved, most patients return to non-strenuous work
2 weeks
Significant improvement in swelling, diet normalizing
3-4 weeks
Most activities resumed, light exercise permitted
6 weeks
Contact sports and vigorous activities allowed, final result emerging
3 months
Final result visible, residual numbness typically resolved
Expected Results
Chin augmentation produces a visible improvement in facial profile and balance that is immediately apparent after surgery, with the final result evident once swelling fully resolves over four to eight weeks. The chin appears more projected, the jawline is better defined, and the relationship between the nose and chin is harmonized. Many patients find that chin augmentation makes their nose appear smaller and their neck more sculpted without any additional procedures.
Chin implant results are considered permanent as long as the implant remains in place. Sliding genioplasty results are permanent, as the repositioned bone heals in its new location. Patient satisfaction rates are high, particularly when chin augmentation is performed in conjunction with rhinoplasty, as the combined effect on facial balance is greater than either procedure alone.
Frequently Asked Questions
What is the difference between a chin implant and sliding genioplasty?
A chin implant involves placing a synthetic implant (usually solid silicone) over the existing chin bone to add projection and contour. The procedure is simpler, faster, and the implant can be removed if desired. Sliding genioplasty involves cutting the chin bone and repositioning it, offering more versatile three-dimensional control and using the patient's own bone. Genioplasty is preferred for larger advancements (greater than 8 to 10 millimeters), vertical changes, or correction of chin asymmetry. Your surgeon will recommend the approach best suited to your anatomy and goals.

Can chin augmentation be combined with rhinoplasty?
Yes, chin augmentation and rhinoplasty are frequently performed together in a procedure sometimes called profiloplasty. The nose and chin are the two most prominent features of the facial profile, and their proportional relationship significantly influences facial balance. Enhancing chin projection can make the nose appear smaller and improve the overall profile, sometimes reducing the degree of nasal modification needed. Combining the procedures is safe, efficient, and produces a more harmonious result than either procedure alone.

Will I have numbness after chin augmentation?
Temporary numbness of the lower lip and chin is common after chin augmentation due to stretching or temporary irritation of the mental nerve, which provides sensation to this area. Numbness typically resolves gradually over several weeks to a few months. Permanent numbness is rare, occurring in less than 2 percent of cases [1]. Sliding genioplasty has a slightly higher incidence of temporary numbness compared to implant surgery because the bone cut is made near the nerve. Your surgeon will discuss nerve-related risks during consultation.

Factors affecting cost:
The cost of chin augmentation varies based on the technique used. Chin implant surgery is generally less expensive than sliding genioplasty due to the shorter operative time and less complex nature of the procedure. Custom implants cost more than standard off-the-shelf designs. Surgeon experience, geographic location, and facility fees all influence pricing. When combined with rhinoplasty or other procedures, the incremental cost of adding chin augmentation is typically less than having it performed as a standalone procedure.
Implant material costs, anesthesia fees, and post-operative imaging (if needed) are additional factors. Chin augmentation is considered a cosmetic procedure and is not covered by insurance, though sliding genioplasty may be partially covered if performed to correct functional bite issues.
