Chin Augmentation in Murrieta
Chin augmentation enhances the projection and contour of the chin through surgery to improve facial balance and harmony. It can be performed with an alloplastic implant, most commonly solid silicone, or by sliding genioplasty, which repositions the chin bone itself. The operation is frequently combined with rhinoplasty to bring the face into proportion.
At a Glance
- Chin augmentation is frequently combined with rhinoplasty, with up to 25% of cosmetic rhinoplasty cases including concurrent chin enhancement[5]
- Implant-based chin augmentation reports overall patient satisfaction rates of approximately 97.8%[5]
- Solid silicone (Silastic) is the most commonly used implant material due to its biocompatibility and ease of removal if needed[5]
- Chin augmentation can be performed through an intraoral incision (inside the mouth) or a submental incision (under the chin), each with distinct advantages[4]
Overview
Chin augmentation, also called mentoplasty or genioplasty, reshapes an underprojected chin, improves facial proportions, or restores chin volume lost from the soft tissue. It is an established facial plastic surgery procedure and is often performed with rhinoplasty to balance the relationship between the nose and chin.
There are two primary approaches. Implant augmentation places an alloplastic implant, most commonly solid silicone (Silastic), directly on the chin bone through a small incision. Sliding genioplasty uses a controlled bone cut at the mandibular symphysis. The chin segment can then be moved forward, backward, or vertically and held in position with plates and screws.
The choice depends on the deficiency being corrected. An implant typically addresses horizontal projection alone. Sliding genioplasty can change vertical height, correct transverse asymmetry, and address combined deficiencies that an implant cannot.
What to expect
- Consultation including facial analysis, photography, and discussion of aesthetic goals and chin projection needs
- Preoperative assessment of dental occlusion, chin anatomy, and determination of implant versus genioplasty approach
- Administration of local anesthesia with sedation or general anesthesia depending on procedure complexity
- Placement of incision either under the chin (submental approach) or inside the lower lip (intraoral approach)
- For implant augmentation, creation of a precise pocket on the anterior mandible sized to the selected implant
- Selection, sizing, and placement of the chin implant onto the bone, with optional screw fixation
- For sliding genioplasty, horizontal osteotomy below tooth roots followed by repositioning and plate fixation of the chin segment
- Assessment of symmetry and projection with the patient positioned upright when possible
- Closure of incisions with absorbable sutures (intraoral) or fine sutures (submental)
- Application of external chin dressing or compression bandage to minimize swelling
How a chin augmentation works
- For implant augmentation, a pocket is created directly on the front surface of the mandible through an incision under the chin or inside the lower lip. The submental approach uses a 2 cm midline incision behind the natural chin crease. The intraoral approach uses a 2–3 cm gingivolabial incision inside the mouth.
- The implant may be solid silicone, porous polyethylene (Medpor), or another alloplastic material. It is selected and shaped for the planned augmentation, positioned on the bone, and may be secured with screws or sutures to prevent migration.
- Sliding genioplasty is performed through an intraoral approach. A horizontal osteotomy is made below the tooth roots, freeing the chin segment so it can be advanced, set back, or adjusted vertically. Titanium plates and screws hold the segment in its new position.
- Cartilage or bone grafts may be added to either technique when more volume or structural support is needed. Some patients may also benefit from neck liposuction to improve jawline definition.
- A chin is assessed in relation to the nose and neck, not by itself. An underprojected chin can make a normal nose appear large and the jawline appear soft. What looks like a nose problem may come from the chin, or from both structures. Dr. Banthia assesses the profile as one unit. When both structures need correction, he plans chin augmentation and rhinoplasty as one operation and performs both procedures himself. The profile is measured once, and both procedures are staged against that plan rather than referring part of the treatment to another surgeon on another timetable.
When it's recommended
- Horizontal chin deficiency (microgenia or retrogenia)
- Facial imbalance between the nose and chin profile
- Pre-jowl volume loss contributing to an aged lower face appearance
- Soft tissue chin deficiency from muscular atrophy
- Asymmetry of the chin requiring correction
- Weak or receding chin affecting facial proportions
- Chin deficiency identified during rhinoplasty planning

Recovery & aftercare
- An external compression dressing or bandage is typically worn for several days after surgery
- Initial swelling and bruising generally subside within 1 to 2 weeks
- Patients with intraoral incisions may be placed on a liquid or soft diet for several days
- Most patients return to desk work and normal daily activities within approximately one week
- Sutures are typically removed or dissolve within 7 to 10 days
- Strenuous physical activity and contact sports should be avoided for 4 to 6 weeks
- Numbness of the lower lip may persist for several weeks but typically resolves
- Final results become apparent as swelling resolves over several weeks to a few months
Alternatives
- Nonsurgical chin augmentation using injectable dermal fillers (temporary, typically lasting 12 to 18 months)
- Sliding genioplasty (for patients requiring vertical or transverse correction beyond implant capability)
- Fat grafting to the chin (using the patient's own tissue for moderate volume enhancement)
- Orthodontic or orthognathic surgery (for chin deficiency related to dental malocclusion)

Frequently Asked Questions
- Chin augmentation is surgery that increases the size or projection of the chin to improve facial balance and proportion. It is most commonly performed by placing a solid silicone implant on the chin bone. Sliding genioplasty, which repositions the chin bone itself, may be used for more complex corrections. Chin augmentation is also frequently combined with rhinoplasty.
- Chin augmentation is performed under local anesthesia with sedation or general anesthesia, so patients do not feel pain during the procedure. Afterward, most patients experience mild to moderate discomfort, pressure, and tightness around the chin. Prescribed pain medication typically manages this discomfort, which resolves within the first few days.
- Chin augmentation is generally considered safe when performed by a qualified, board-certified surgeon. Infection rates are reported at less than 1%, and overall patient satisfaction is high. As with any operation, chin augmentation has risks, which are discussed during consultation.
- Most patients return to work and normal daily activities within about one week. Swelling and bruising generally subside within 1 to 2 weeks. Temporary lower-lip numbness may remain for several weeks but usually resolves. The final result becomes apparent over several weeks to a few months as the remaining swelling subsides.
- A chin implant adds projection with a synthetic material, most commonly solid silicone, placed on the chin bone. Sliding genioplasty cuts and repositions the chin bone itself. An implant is typically used when the deficiency is horizontal. Sliding genioplasty can address vertical height changes and more complex asymmetries. The choice depends on the patient’s anatomy and goals.
- Chin augmentation may not be appropriate for someone with dental malocclusion that requires orthodontic correction, a history of implant rejection, an active infection at the surgical site, or unrealistic expectations. A thorough evaluation during consultation determines which approach, if any, is suitable.
- Not always the procedure a patient initially expects. Chin and nose projection affect each other’s apparent size. A modest increase in chin projection may create the profile change a patient thought would require nose surgery, even though the nose itself has not changed. Dr. Banthia measures the profile during consultation and identifies which structure is driving the impression. That may lead to the smaller of the two operations or to both procedures in one sitting. If the chin deficiency is horizontal alone, an implant can address it. An implant does not correct a vertical deficiency.
- Injectable chin augmentation exists and typically lasts 12 to 18 months, but it is not included on this surgical menu, which carries no cosmetic injectables. Its limit is the degree of correction: filler can soften a contour, but it cannot advance the bony point of the chin when a receding profile requires more projection. During consultation, Dr. Banthia distinguishes a contour problem from a projection problem.

- Retrognathia with dental malocclusion requiring orthodontic or orthognathic correction
- Prior history of implant rejection or significant foreign body reaction
- Active infection at the planned surgical site
- Uncontrolled bleeding disorders or anticoagulant use without medical clearance
- Body dysmorphic disorder or unrealistic expectations regarding outcomes
- Significant medical conditions that increase surgical risk (uncontrolled diabetes, severe cardiopulmonary disease)
- Transverse chin asymmetry that exceeds the corrective capability of implant placement alone
Possible risks
- Swelling and bruising around the chin and lower face (expected, typically resolves within 1 to 2 weeks)
- Temporary numbness or altered sensation of the lower lip and chin (paresthesia, usually transient)
- Implant migration or malposition (reported at approximately 5% for implant-based procedures)
- Bone resorption beneath the implant over time (reported at approximately 8.3% in some studies)
- Infection at the surgical site (reported at less than 1% incidence)
- Implant extrusion through the incision (rare, reported at approximately 0.4%)
- Asymmetry or contour irregularity requiring revision
- Capsular contracture (thickened scar tissue forming around the implant)
- Hematoma or seroma (fluid accumulation)
- Damage to the mental nerve resulting in prolonged numbness
- Unsatisfactory aesthetic result requiring revisional surgery
- Anesthesia-related risks
