The lower face sets the frame. When the jaw and chin are right, the rest of the face falls into proportion.
The jawline and chin are among the strongest gender markers in the face. A wide, square jaw reads as masculine. A tapered, V-shaped lower face reads as feminine. Jaw and chin contouring reshapes the mandible and chin bone to produce the lower facial proportions that match your identity — whether that means narrowing and softening or widening and projecting.
Free, no-obligation — you pay the hospital directly with no markup.
Jaw and chin contouring is a group of bone-sculpting procedures that modify the shape of the mandible and chin to change the lower facial silhouette. For feminization, the mandibular angles are reduced and the chin is narrowed, shortened, and sometimes set back — creating a smooth transition from ear to chin and an overall oval or heart-shaped face. For masculinization, custom implants or bone advancement widen the jaw angles and project the chin forward.
All bone work on the jaw and chin is done through incisions inside the mouth, between the lower lip and the gum. No external cuts, no visible scars. The surgeon uses oscillating saws, piezoelectric instruments, and rotary burrs to reshape the bone with precision. Pre-operative 3D CT imaging guides every cut.
Jaw and chin contouring requires maxillofacial or craniofacial surgical skill, 3D imaging, and accredited hospital infrastructure. Thailand's top centres deliver all three at significantly lower cost.

Prices are approximate and vary by technique, surgeon, and hospital. Your personalised quote will include a full cost breakdown.
Jaw and chin contouring in Thailand typically costs between $3,500 and $6,300, depending on the number of procedures combined and whether reduction or augmentation is involved. A standalone chin genioplasty sits at the lower end. Adding mandibular angle reduction or custom jaw implants increases the total.
The total includes surgeon fees, general anaesthesia, operating theatre, one night in hospital, 3D CT imaging, titanium hardware or implants, post-operative medications, and follow-up appointments. Surgeon fees reflect the technical precision required for bone work near the inferior alveolar nerve.
The main factors are scope and complexity. Mandibular angle reduction plus genioplasty costs more than either procedure alone. Custom 3D-printed implants for masculinization are more expensive than standard implants. Piezoelectric instrumentation, which offers greater precision and nerve safety, may add to the cost at some facilities.
Pricing varies by the complexity and scope of the procedure. Typical ranges at our partner hospitals in Thailand:
Exact pricing is confirmed after your consultation and treatment plan are finalised.
Jaw and chin contouring in Thailand costs 40–60% less than equivalent procedures in the US ($10,500–$19,300), Australia (A$9,800–A$17,500), and UK (£8,800–£15,800). The difference reflects Thailand's lower operating costs. Surgical techniques, imaging, and hardware are the same as those used in international centres.
The direction of change — reduction for feminization versus augmentation for masculinization — determines which techniques are used. Both are performed through the same intraoral approach.
Mandibular angle reduction narrows the lower face by shaving the flared jaw angles. Reduction genioplasty repositions the chin bone to decrease width, height, or projection. Combined, they transform a square lower face into a tapered oval or heart shape. All incisions inside the mouth.
Custom implants or bone advancement add width to the jaw angles and projection to the chin. Sliding genioplasty advances the chin bone forward using titanium fixation. Jaw angle implants create the flared, square silhouette testosterone cannot build on its own.
Every cut and every implant is planned from 3D CT data. The inferior alveolar nerve — which provides sensation to the lower lip and chin — is mapped and protected throughout. Here are the core techniques.
The flared posterior jaw angles are reduced using an oscillating saw or piezoelectric instrument through an intraoral incision. The outer cortex of the mandible may also be shaved to narrow the body of the jaw. This is the primary technique for transforming a square jaw into a tapered lower face.
A horizontal osteotomy separates the chin bone into a free segment that is repositioned — moved backward, shortened vertically, or narrowed by removing a central wedge. The bone is fixed with titanium plates. This provides millimetre-level control over chin shape in three dimensions.
For patients seeking a stronger lower face, sliding genioplasty advances the chin bone forward, or a custom implant is placed to increase projection and width. Jaw angle implants are placed over the mandibular angles to create a wider, more angular lower face.
Significant lower face swelling peaks around day two, with bruising extending down the neck in some patients. Your jaw feels stiff and mouth opening is limited. A soft or liquid diet is mandatory. You remain in hospital overnight with IV pain management and a compression garment around the jaw.
Swelling shifts downward and begins to reduce. Discharge to your hotel with oral medications, antibacterial mouthwash, and dietary guidance. Chewing remains restricted — soups, smoothies, and mashed foods only. Daily coordinator check-ins continue.
Most visible swelling resolves and the new lower face contour becomes apparent. Intraoral sutures dissolve on their own. Softer solid foods can be reintroduced gradually. Lower lip and chin numbness is typical and improves over the coming weeks. Light activity is fine — no contact sports.
Residual deep swelling dissipates fully, revealing the definitive jaw and chin shape. Sensation returns progressively. Bone healing completes by approximately three months, and by six months the contour has settled into its permanent form.
Most patients are cleared to fly 10–14 days after surgery. Swelling will still be visible but does not pose a risk during air travel. Stay hydrated, avoid chewing hard foods during the flight, and follow your surgeon's post-operative instructions for the flight home.
Desk work can resume 2–3 weeks after surgery. Light walking is encouraged from day one. Gym and cardio should wait 6 weeks. Contact sports and activities with jaw impact risk need at least 3 months. Full bone healing takes approximately three months.
The new lower face contour is visible once the worst swelling subsides around week three. The definitive shape settles by 3–6 months as deep swelling resolves and bone healing completes. Sensation returns over the same period. What you see at month six is your permanent result.
Jaw and chin surgery involves bone modification near the inferior alveolar nerve and dental roots. With experienced maxillofacial surgeons and proper imaging, the procedure has a strong safety record — but you should understand the potential complications.
Pre-operative 3D CT imaging maps nerve positions, dental roots, and bone thickness before any cut is planned. This imaging is not optional — it is the foundation of safe bone surgery. Every risk specific to your anatomy and procedure is discussed before you confirm.
Yes — at JCI-accredited hospitals with surgeons certified by the Thai Board of Plastic and Reconstructive Surgery or equivalent maxillofacial credentials. 3D CT planning, piezoelectric instruments, and experienced surgical teams reduce risk to levels comparable with leading international centres. The procedure is well-established and performed at high volume at our partner hospitals.
Ensure 3D CT imaging is standard in your surgeon's workup — never proceed without it. Verify board certification in plastic, reconstructive, or maxillofacial surgery. Follow smoking cessation instructions precisely — nicotine impairs bone healing. Maintain good dental hygiene before surgery and treat any active infections first. Report any previous jaw surgery or TMJ issues during consultation.
Temporary numbness of the lower lip and chin is very common after jaw and chin surgery because the inferior alveolar nerve runs through the mandible near the surgical site. In the large majority of patients, full sensation returns within three to six months. Permanent numbness is uncommon but should be discussed as a possibility before surgery.
Bone surgery of the jaw demands specific craniofacial or maxillofacial expertise. Here is what distinguishes the right surgeon and hospital for this procedure.
Our partner hospitals are JCI-accredited with in-house 3D CT imaging, piezoelectric instruments, and dedicated craniofacial or maxillofacial surgery teams. These are full-scale hospitals that can manage any complication internally. The infrastructure required for precise jaw bone surgery — imaging, instruments, hardware — is standard at these facilities.
Our partner surgeons are board-certified with specific training in craniofacial bone work. They perform mandibular angle reduction, genioplasty, and jaw augmentation regularly as part of gender-affirming surgical practice. Several have international training from centres known for V-line and jaw reshaping techniques.
Board certification in plastic, reconstructive, or maxillofacial surgery is essential. Ask specifically about jaw contouring case volume and experience with gender-affirming patients. Confirm that 3D CT planning is a standard part of their process. Review before-and-after photos of patients with similar anatomy. A surgeon who discusses nerve risk and imaging findings openly — rather than glossing over them — is demonstrating the right approach.
Jaw and chin contouring produces permanent bone changes. Here is what realistic outcomes look like.
Feminizing jaw contouring eliminates the wide jaw angle and narrows the chin, creating a smooth, tapered lower face. The transition from ear to chin becomes a gentle curve rather than an angular step. Masculinizing jaw augmentation adds width and angularity to the lower face, creating the square jaw and projecting chin that define a masculine profile. All changes are structural and permanent.
The new contour becomes visible as swelling subsides over weeks 2–4. The definitive shape settles by month 3–6. Your surgeon will use 3D CT imaging during consultation to show you how the bone will be modified and what the expected change will look like. This is the point to ask specific questions about what your anatomy allows and what the limits of bone reshaping are.
Most patients need 10–14 days in Thailand. Here is how to structure the trip.
Plan for 10–14 days. This covers pre-operative CT imaging and consultation (day 1–2), surgery, one night in hospital, and the recovery period including dietary progression and follow-up appointments. If custom implants are needed, allow additional lead time for fabrication before the surgery date.
Your coordinator manages imaging, transfers, scheduling, and follow-ups. Surgical quotes cover surgeon fees, anaesthesia, hospital stay, CT imaging, hardware, and aftercare. Flights and accommodation are arranged separately. Your coordinator can recommend nearby hotels and help with dietary arrangements for the soft-food recovery period.
Stock up on protein-rich soups, smoothies, and meal replacement shakes before surgery. You will be on a liquid diet for the first few days, progressing to soft foods by the end of week one. Hard or chewy foods should be avoided for six weeks to allow bone healing. Your coordinator can help source suitable options near your hotel.
