A softer silhouette—designed for balance, safety, and authenticity
The lower third of the face—your jawline and chin—can be one of the strongest cues in how a face is read. For many people, a wider, squarer jaw or a broader chin can feel like it’s telling a story that doesn’t match who they are.

At Evolve Your Life in Chicago, we approach lower third feminization with care and intention. Dr. Amir Dorafshar brings a craniofacial surgeon’s understanding of bone structure, symmetry, and nerve anatomy to every plan—because jaw and chin contouring isn’t just about making the face “smaller.”
It’s about creating a shape that feels more aligned, while prioritizing safety, sensation, and natural-looking harmony with the rest of your features.
What Is Lower Third Feminization?
Lower third facial feminization focuses on contouring the jawline and chin, often called V-line reduction. In general, cisgender male-pattern jaws tend to be wider and more square, while cisgender female-pattern jaws often appear slimmer, smoother, and more tapered. The goal is to reshape the lower face into a softer, more V-shaped contour—improving overall facial proportion and balance.
This isn’t about erasing your features. It’s about shaping them into a form that feels more like your true reflection.
Who Can Benefit from Lower Third Feminization?
Lower third feminization may be a fit for individuals seeking gender-affirming surgery who have a prominent or wide jawline and want a more feminine or V-shaped lower face.
If your goals are subtle, we can plan subtle. If you want a more noticeable change, we can explore that too—always grounded in what your anatomy can safely support.
A Surgeon’s Eye: Anatomy That Matters
Lower third contouring involves working near structures that affect sensation and function—so expertise matters here in a very real way. Key anatomy includes:
- Mandibular angle (gonial angle): where the vertical and horizontal portions of the jaw meet (often contributes to a square jaw look)
- Mental protuberance: the bony structure forming the chin
- Inferior alveolar nerve: provides sensation to the lower jaw
- Mental nerve: supplies sensation to the chin and lower lip
- Masseter muscle: a chewing muscle that can contribute to a stronger, more angular jawline
Dr. Dorafshar’s craniofacial background brings added value in this region because planning isn’t just aesthetic—it’s anatomical strategy.
Masculine vs. Feminine Lower Face Patterns
These patterns aren’t “rules,” and they don’t define anyone’s gender. But they do help explain why certain jaw and chin shapes tend to read more masculine or feminine in everyday perception.
Common male-pattern features
- More prominent flare and a more acute mandibular angle, creating a squarer shape
- Bulkier masseter muscle, contributing to a stronger jaw contour
- Broader, wider chin with greater projection
Common female-pattern features
- A gentler, tapered jawline with a shorter, narrower ramus
- Smoother muscle markings
- A chin that is often shorter in height with a narrower, rounder contour
Your plan is built around you—your structure, your proportions, and the outcome that feels most affirming.
Planning & Imaging
Lower third feminization begins with thorough pre-operative evaluation, often including CT imaging to assess bone structure, nerve pathways, and facial proportions. These images can be used to create 3D models through computer-assisted surgical planning.
That level of planning helps:
- Improve precision and symmetry
- Reduce the risk of injury to surrounding structures
- Support efficient execution in the operating room
- Decrease the likelihood of revision surgery
For patients, this typically means greater clarity, greater confidence, and a plan that’s truly personalized.
Lower Third Feminization Surgical Options
Mandibular Angle Reduction
Mandibular contouring may be performed through an incision inside the mouth, along the lower gumline near the molars. The jaw angle is exposed by carefully dissecting the surrounding soft tissue. Based on your anatomy and goals, there are two primary approaches:
1) Mandibular angle ostectomy
A surgical saw is used to remove a wedge or block of bone at the gonial angle. This can be especially effective for patients with thicker or more prominent jawlines who want a more dramatic reduction.
Considerations: this approach can increase the risk of nerve injury and asymmetry if reductions are not perfectly matched—one reason planning and surgical precision are so important.
2) Mandibular angle burring
A rotary instrument (such as a surgical drill) is used to gently smooth and slim the gonial angle. No large bone segment is removed, and the change can be more subtle.
This approach can be a strong option when the goal is refinement rather than major reduction.
Mandibular V-Line Reduction
V-line reduction reshapes more than just the angles—it can contour the entire bottom edge of the mandible into a slimmer, more tapered silhouette.
A common approach uses an intraoral incision that begins near the back of the lower jaw and extends along the lower gumline toward the incisors. After the bone is exposed, the bottom portion of the mandible—often about 0.5 to 1 cm—may be resected to create a more slender V-shaped contour.
Often best suited for:
- Patients with a square jaw and low angle
- Patients with asymmetry on both sides
Important consideration: this technique can increase the risk of injury to the inferior alveolar and/or mental nerve, which is why surgeon experience and careful planning are essential.
Genioplasty (Chin Reshaping)
Genioplasty reshapes the chin through an incision inside the mouth along the lower gumline. After the chin bone is exposed—carefully protecting the mental nerves—planned bone cuts are made (often guided by 3D planning).
A common technique includes:
- Marking the bone and making one horizontal and two vertical cuts
- Removing the middle portion of bone
- Repositioning the remaining segments to achieve the desired width, height, projection, and symmetry
- Securing the new position with plates and screws
- Closing the incision with dissolvable sutures
Why patients consider genioplasty: it allows adjustment in both vertical and horizontal planes—meaning projection, width, height, and asymmetry can be addressed together.
Considerations: nerve injury and asymmetry risks increase if bone segments are not aligned precisely—again highlighting why craniofacial-level execution matters.
Risks & Considerations
All surgery carries risk, and your consultation should include an honest discussion of what’s most relevant to you. Potential risks of mandibular reduction and genioplasty include:
- Pain, swelling, bleeding
- Infection
- Injury to surrounding structures (nerves, vessels, muscles)
- Numbness in the lower lip and chin (from nerve involvement)
- Asymmetry or dissatisfaction requiring revision surgery
Our promise is transparency: we’ll help you understand your options and build an achievable plan that respects both your goals and your safety.
Lower Third Feminization: What to Expect & Recovery Guidance
Healing is a process—and it’s normal for the lower face to feel tight, swollen, or numb in the early weeks. While everyone’s timeline is different, these guidelines help you plan with confidence:
Swelling and bruising
- Swelling can build quickly and often peaks in the first couple of days
- Most visible swelling improves over the first 1–2 weeks
- Some puffiness can linger for months as tissues fully settle
- Final results typically become clearer over 6–12 months
Eating and drinking
- Start with clear fluids after surgery and advance to soft foods as tolerated
- Avoid very hot foods or drinks initially, as swelling can affect sensitivity
- Follow any personalized dietary guidance you’re given—especially when intraoral incisions are involved
Oral care
- You can brush with a soft toothbrush the night after surgery or the next morning
- Be gentle and avoid vigorous rinsing
- If a mouth rinse is prescribed, use it exactly as directed
Activity and return to routine
- Light activity (like walking) is encouraged within a day or two
- Avoid strenuous exercise, heavy lifting, and bending over for at least 3–4 weeks
- Many patients return to work or social activities in 2–4 weeks, depending on comfort and swelling
Scarring
- Jaw and chin contouring incisions are typically inside the mouth, so there are no visible external scars for these procedures
Questions to Ask about Lower Third Feminization at Your Consultation
If you like to feel informed (and supported) before making a decision, these questions can help guide the conversation:
- Which lower third techniques are best suited to my anatomy and goals?
- How will you protect sensation in the chin and lower lip?
- Would you recommend angle reduction, V-line reduction, genioplasty—or a combination?
- How do you plan for symmetry, especially if I have existing asymmetry?
- What does my recovery timeline look like based on the extent of surgery?
- What are the most relevant risks in my case—and how are they managed?
