Jaw & Chin Augmentation

Masculine faces typically have a broader, more angular jawline and a prominent chin with increased vertical height and projection. In contrast, feminine lower faces tend to be narrower and more tapered, with softer angles and shorter chin height.

Jaw and chin augmentation enhances the width, projection, and shape of the mandible to achieve these masculine features. Depending on the patient’s anatomy and goals, augmentation may involve custom implants, standard implants, or autologous fat grafting for minor adjustments. The goal is to create a defined “jawline-to-chin sweep” with straight lines, sharp mandibular angles, and a square, prominent chin.

The specific surgical technique depends on your facial anatomy and aesthetic goals. Most cases involve a combination of implant-based augmentation and precise soft tissue manipulation to achieve a natural, sculpted appearance.

Custom implants – In many cases, especially those requiring significant enhancement or precise symmetry, we use custom jaw and chin implants. These are designed using virtual surgical planning from a high-resolution CT scan to match the patient’s bony anatomy and surgical goals. The implants are 3D printed from medical-grade materials and secured to the bone using titanium screws for stability.

Standard implants – For patients needing more modest augmentation, standard prefabricated implants may be used. These are shaped intraoperatively and secured in a similar manner.

Osteotomies (bone reshaping) – In some cases, especially when soft tissue volume is not a concern but bony projection must be increased, sliding genioplasty (chin osteotomy) may be performed to reposition the bone itself.

Fat grafting – For subtle contouring or softening of transitions, fat grafting can complement implant-based augmentation.

All incisions are placed inside the mouth (intraoral), leaving no external scars. This procedure is often performed alongside other FMS procedures such as rhinoplasty, forehead augmentation, or thyroid cartilage enhancement to harmonize the overall facial aesthetic.

Jaw augmentation is an excellent option for facial masculinization patients who wish to reshape their lower facial profile to better reflect their unique individuality and gender expression. It can be performed on FTM, nonbinary, and gender nonconforming individuals seeking a more angular, sharper look in the jaw and chin. Multiple variables are involved in determining candidacy for the procedure. Candidates for jaw and chin augmentation typically have one or more of the following characteristics:

• A narrow or tapered lower face
  
• A weak or recessed chin
  
• Lack of jaw angle definition
  
• Disproportion between the upper and lower facial thirds
  

Candidates should also be in good general health, have well-controlled medical or mental health conditions, and meet WPATH criteria for gender-affirming surgery. These procedures are commonly performed in patients undergoing full facial masculinization, but they may also be performed as standalone interventions.

Dr. Marano and Dr. Keith will conduct a private consultation that includes a detailed physical assessment and medical review to ensure no contraindications are present and that the surgery will be safe, successful, and rewarding for you. 

You may not be a good candidate for jaw augmentation in at GAMMA in New York City and New Jersey if you have any of the following characteristics:

• You are a heavy drinker, drug user, or smoker
• You have uncontrolled diabetes or hypertension
• You suffer from a bleeding or clotting disorder
• You struggle with lung or heart disease
• You have an active dental infection
• You’ve had previous trauma in the lower facial area
• You’ve undergone previous jaw surgeries

The first step in facial masculinization is to meet with Dr. Marano or Dr. Keith for a private consultation at GAMMA in New York City or New Jersey. During this time, you will discuss your goals and medical history with our team, who will then create a customized treatment plan according to your unique anatomy, comfort levels, and goals. Prior to consultation, you should ensure the following:

• Provide Mental Health Letter – Many insurance providers and surgical guidelines require a letter from a qualified mental health professional confirming a diagnosis of gender dysphoria and the patient’s readiness for surgery. This letter should follow WPATH (World Professional Association for Transgender Health) standards and address the patient’s understanding of the procedure and its implications. Our team will assist in ensuring the proper language is used and the provider is appropriately credentialed
• Quit Smoking – Nicotine constricts blood vessels and significantly increases the risk of complications, including poor wound healing and tissue loss. Patients must stop using all nicotine products—including cigarettes, vapes, nicotine patches, and gum—at least 4-6 weeks before and after surgery.
• Manage Medications – You may be asked to discontinue certain medications that increase surgical risks.
• Well-Controlled Medical or Mental Health Issues / Medical Clearance – To ensure safe surgery and recovery, patients with underlying medical conditions such as diabetes, high blood pressure, or psychiatric conditions should have them well-managed. Medical clearance from a primary care provider or specialist is required.
• BMI Cutoff – There is no strict BMI cutoff for facial masculinization at GAMMA. Every patient is evaluated individually, considering overall health and surgical goals rather than BMI alone.
• Insurance Coverage – GAMMA works with various insurance providers to help patients access gender-affirming surgery. Our team assists with insurance verification, prior authorization, and necessary documentation. Patients should check with their insurance carrier regarding coverage criteria, including mental health letters and medical clearance requirements.
• Complete Your Consultation – You will undergo a detailed consultation with Dr. Marano or Dr. Keith to ensure your expectations are realistic and your health supports the treatment process. Our team will discuss the risks and benefits, recovery and results, of facial masculinization.
• CT Scan for Virtual Surgical Planning: A CT scan will be performed before the surgery to help the surgeon assess the anatomy of the frontal bone. This scan provides detailed images that guide the surgical approach via virtual surgical planning.

Virtual Surgical Planning (VSP) is an advanced, cutting-edge technology that allows surgeons to plan facial masculinization surgeries with extreme precision and accuracy. This process involves creating a 3D reconstruction of the patient’s facial skeleton, which provides a detailed and accurate representation of the bone structure. Using this 3D model, the surgeon can plan the post-operative bony structure and make decisions about the necessary adjustments.

One of the key benefits of VSP is its ability to provide millimeter-level accuracy in surgical planning, ensuring that the changes made to the facial bones are tailored to the patient’s unique anatomy and desired outcomes. The surgeon uses custom 3D-printed implants and screws, which are created specifically for the patient based on the virtual plan. These guides and plates help the surgeon achieve precise cuts during the procedure, reducing the risk of complications and improving the consistency of results.

VSP is particularly beneficial in complex surgeries, such as jaw and chin augmentation, where the margins for error are minimal. By using this technology, the surgeon can optimize the approach, anticipate potential issues, and achieve the most aesthetically pleasing and functional outcomes for the patient.

On the day of surgery, you will arrive early for preoperative check-in, and the surgeon will review the surgical plan. The procedure is performed under general anesthesia. In many cases, jaw augmentation is performed in conjunction with other facial gender surgery procedures, and you may require an overnight hospital stay for monitoring.

Recovery time varies for each patient and depends on several factors, including the individual’s healing ability, the specific techniques utilized, and whether jaw bone augmentation is combined with other treatments or procedures.

• Hospital Stay: Most patients will spend 1-2 nights in the hospital after surgery, especially if additional facial gender surgery procedures are performed.
  
• Swelling & Bruising: Expect swelling and bruising around the forehead and eyes, which will peak within 2-3 days and gradually improve over 2-3 weeks. Final swelling may take several months to resolve.
  
• Activity Restrictions: You will need to avoid strenuous physical activity for 2-4 weeks, especially lifting and bending, which could increase swelling or put stress on the healing tissues. It is important to sleep with the head elevated, either in a recliner or with multiple pillows, to limit facial swelling.
  
• Return to Work: Most patients can return to work 4 weeks after surgery, depending on the nature of their job and comfort level.
  
• Final Results: The final aesthetic results of jaw augmentation may take up to 12-18 months to fully manifest, as swelling continues to subside and tissues heal.

In terms of results, patients may notice a more prominent jaw surface right away after surgery. Swelling and bruising can temporarily obscure your final results, however. Rest assured, within a few months, you will start seeing dramatic improvements that only improve with time as you heal.

The likelihood of complications with facial gender surgery is greatly reduced by choosing fellowship-trained, board-certified surgeons such as  Dr. Marano and Dr. Keith in New York City and New Jersey. However, the procedure does come with certain inherent risks to be aware of. These include the following:

• Bleeding – While uncommon, excessive bleeding can occur during or after the procedure.
  
• Infection – As with any surgery, there is a small risk of infection. This is usually managed with antibiotics, but may require surgery
  
• Lip and Chin Numbness – Most patients will experience temporary numbness in the chin and lower lip area due to nerve irritation during surgery.
  
• Swelling/Bruising – Swelling and bruising are expected but will resolve over time.
  
• Pain – Postoperative pain is typically mild to moderate and managed with prescribed pain medications.

Insurance carriers will typically cover gender affirmation surgery, including facial gender surgery, when it is performed to treat gender dysphoria, a condition in which the patient’s outer traits do not reflect their authentic gender identity. You’ll need a letter from a mental health provider detailing your decision to undergo facial gender surgery. Our team can go over the insurance requirements in greater detail during your consultation.

• Resources – For patients traveling to NYC for surgery, GAMMA provides recommendations for LGBTQ+ friendly accommodations, post-op caregivers, and recovery services. Our team can also assist with logistics such as medical transport and aftercare arrangements.
• Requirements – Out-of-town patients must plan to stay in NYC for at least two weeks after surgery to ensure proper healing and attend necessary post-operative appointments. We encourage having a trusted friend, family member, or professional caregiver for the first few days post-surgery.
