Chin Augmentation
Newport Beach & Beverly Hills | Dr. Monica Kieu, DO, FACS
Why Chin Projection Matters
The chin is a cornerstone of facial balance. In profile, the relationship between the nose, lips, and chin determines how harmonious — or how off-balance — a face appears. A chin that lacks forward projection can make the nose appear larger than it is, weaken the jawline, and create the appearance of a double chin even in patients without significant submental fat.
Conversely, a well-projected chin anchors the lower face, strengthens the jaw-to-neck transition, sharpens the profile, and creates overall facial proportion. Chin augmentation is one of the most powerful — and underutilized — tools in facial balance. It is frequently performed alongside rhinoplasty, facelift, or neck procedures to complete a comprehensive aesthetic result.
Dr. Kieu offers three approaches to chin augmentation, ranging from a five-minute injectable treatment to a permanent bone-repositioning procedure. The right option depends on the degree of correction you need, whether the change should be reversible, and your overall facial anatomy and goals.
Your Three Options at a Glance
Chin Filler
Dermal filler — most commonly a hyaluronic acid product such as Juvederm Voluma or Radiesse — can be injected directly into the chin to add projection, lengthen the chin vertically, or improve symmetry. Results are immediate, require no recovery, and can be dissolved with hyaluronidase if desired.
Chin filler is an excellent option for patients who want to trial chin projection before committing to a permanent result, those with mild-to-moderate projection deficiency, or patients who are not candidates for or do not want surgery. It is also useful as a refinement adjunct after surgical chin augmentation.
Best suited for:
- Mild to moderate chin underprojection
- Patients wanting a preview of surgical results before committing
- Minor asymmetry or vertical shortening
- Those who prefer a non-permanent, adjustable approach
- Patients combining with lip filler, jawline filler, or other injectables
Limitations: Filler cannot address significant projection deficiency, cannot reposition bone, and requires ongoing maintenance every 12–18 months. In patients with very thin chin skin, repeated filler can occasionally cause irregularity over time.
Solid Silicone Chin Implant
A solid silicone chin implant is the most widely performed surgical chin augmentation technique and delivers permanent, reliable, and natural-feeling projection. Silicone implants are available in a variety of sizes and shapes — including extended styles that also augment the lateral jawline — allowing Dr. Kieu to precisely match the implant to your facial anatomy and desired outcome.
The Procedure
The procedure is typically performed under local anesthesia with sedation or general anesthesia, depending on patient preference and whether it is being combined with other procedures. Dr. Kieu makes a small incision either just inside the lower lip (intraoral, no visible scar) or in the natural crease beneath the chin (submental, a nearly imperceptible scar). A pocket is created directly over the chin bone and beneath the muscle, the implant is positioned, and a small titanium screw is placed to secure it in position.
The procedure takes approximately 45–60 minutes as a standalone surgery. When combined with rhinoplasty, neck lift, or facelift, it is performed concurrently without significant additional recovery.
Recovery
Swelling and firmness around the chin are expected for the first 1–2 weeks. Most patients feel comfortable in social settings within 10–14 days. The implant softens and settles into its final position over 4–6 weeks. Patients should avoid direct pressure on the chin (sleeping face-down) for the first 4 weeks.
Implant Options
Dr. Kieu uses medical-grade solid silicone implants in a range of styles. Standard implants increase forward projection of the central chin. Extended anatomical implants additionally augment the lateral mandible, improving the appearance of the entire lower jaw. During consultation, sizing and style are determined using facial measurements and, often, digital imaging.
Best suited for:
- Moderate to significant chin underprojection
- Patients wanting a permanent, single-treatment result
- Those combining with rhinoplasty, facelift, neck lift, or liposuction
- Patients who want both central projection and lateral jaw improvement
- Anyone who has trialed filler and wants to make the result permanent
Limitations: Implants add projection and width but do not reposition the chin bone. They are not ideal for patients with very significant skeletal discrepancies, vertical chin deficiency, or those who need combined jaw correction (for whom sliding genioplasty may be preferable).
Sliding Genioplasty
Sliding genioplasty is an osteotomy procedure — meaning it involves surgically cutting and repositioning the chin bone itself. A horizontal cut is made through the lower portion of the mandibular symphysis, and the detached chin segment is moved to the desired position — forward, backward, upward, downward, or at an angle — then secured with titanium plates and screws.
Because it works with your own bone rather than introducing a foreign implant, sliding genioplasty offers the most precise and versatile dimensional control of any chin augmentation approach. It is the procedure of choice for patients with complex chin deformities, significant skeletal discrepancy, or those requiring correction in multiple planes simultaneously.
What Sliding Genioplasty Can Correct
- Horizontal advancement — the most common movement; increases forward chin projection
- Horizontal setback — reducing a chin that is too prominent
- Vertical lengthening or shortening — correcting a chin that is too short or too long vertically
- Asymmetry correction — rotating or angling the chin segment to address left-right asymmetry
- Combination movements — repositioning in multiple planes simultaneously
The Procedure
Sliding genioplasty is performed under general anesthesia through an incision made entirely inside the mouth (no external scars). Dr. Kieu cuts the lower chin bone along a precisely planned line, repositions it to the predetermined coordinates, and fixes it in its new location with titanium hardware. The procedure typically takes 1.5–2 hours as a standalone surgery.
Recovery
Swelling after sliding genioplasty is more pronounced and longer-lasting than after implant placement, typically peaking in the first 48–72 hours and resolving substantially within 2–3 weeks. Some numbness of the lower lip and chin area is expected and resolves over several weeks to months as sensation returns. A soft diet is recommended for 4–6 weeks. Final result is fully visible at 3–4 months.
Best suited for:
- Patients with significant chin underprojection or overprojection
- Those needing correction in multiple planes (forward and vertical, for example)
- Patients with notable chin asymmetry
- Individuals who prefer a solution using their own anatomy rather than an implant
- Cases where an implant would not provide sufficient correction
- Patients undergoing orthognathic (jaw) surgery who need chin refinement
Limitations: More involved recovery than implant placement. Not reversible. Requires general anesthesia. For patients with straightforward forward projection needs, a chin implant typically offers equivalent aesthetic results with a simpler procedure and faster recovery.

How Dr. Kieu Approaches Consultation
A chin augmentation consultation with Dr. Kieu begins with an in-depth analysis of your facial proportions — evaluating chin position in three planes, jaw structure, profile balance, skin thickness, and the relationship between your chin, nose, lips, and neck. She uses this assessment alongside your goals and lifestyle to recommend the approach that will produce the most natural, lasting, and satisfying result.
For patients who are undecided between filler and surgery, it is entirely reasonable — and sometimes advisable — to begin with filler to experience the aesthetic effect of increased projection before committing to a permanent surgical result.
For out-of-town patients, virtual consultations are available as a first step.
Frequently Asked Questions
How do I know which option is right for me?
The right approach depends on the degree of correction needed, whether you want a permanent result, your overall facial anatomy, and whether you are combining chin augmentation with other procedures. Dr. Kieu will make a specific recommendation during your consultation based on a thorough evaluation. Many patients with moderate projection deficiency are excellent candidates for a chin implant; those with more complex needs or multi-plane correction typically benefit most from sliding genioplasty.
Can chin augmentation make my nose look smaller?
Yes — this is one of the most common observations patients make after chin augmentation. Because facial proportion is relative, adding projection to a recessed chin restores balance to the lower face and can make the nose appear less prominent, even though the nose itself has not changed. This is why Dr. Kieu frequently recommends chin evaluation alongside rhinoplasty consultations.
Is chin implant surgery painful?
Discomfort is typically mild to moderate and well-managed with prescription pain medication for the first 2–3 days. Most patients transition to over-the-counter pain relief by day 3–4. Pressure and tightness around the chin are more common complaints than significant pain.
Will the implant be visible or feel unnatural?
No. Solid silicone chin implants, when properly sized and positioned, are neither visible nor palpable through the overlying tissue. They are designed to sit flush against the bone and integrate naturally with the soft tissue envelope. Patients consistently describe healed results as looking and feeling like their own anatomy.
Can a chin implant be removed if I change my mind?
Yes. Silicone chin implants are fully removable under local anesthesia through the same incision used for placement. Removal is a straightforward procedure. After removal, the chin typically returns to close to its preoperative appearance, with some patients noting minor soft tissue changes from the pocket that was created.
Does sliding genioplasty leave scars?
No external scars. The incision for sliding genioplasty is made entirely inside the mouth, in the gingival sulcus (between the lower lip and gums). There is no skin incision and no visible scar.
Can I combine chin augmentation with a rhinoplasty or neck lift?
Yes, and this is very common. Chin implant placement adds minimal operative time and recovery when performed alongside rhinoplasty or facelift. The combination frequently produces a more harmonious total result than either procedure alone.
What is the cost of chin augmentation in Newport Beach?
Cost varies depending on the approach selected (filler, implant, or genioplasty), anesthesia, facility fees, and whether the procedure is combined with others. Dr. Kieu's team will provide a personalized quote during your consultation. Financing options are available.
