Direct answer summary
Double jaw surgery, also called orthognathic surgery, repositions both the upper and lower jaws to improve facial balance and bite function. Before surgery, many people struggle with a long or protruding face, recessed chin, facial asymmetry, gummy smile, or difficulty biting and chewing. After surgery, the goal is a more balanced profile, smoother jawline, improved bite, and greater confidence in photos and daily life. Results develop gradually over several months as swelling goes down.
For international patients visiting a specialized plastic surgery clinic in Seoul, the journey usually includes online consultation, detailed facial and bite analysis, treatment planning with 3D imaging, the surgery under general anesthesia, a short hospital stay, and regular follow-up until the bite and facial shape are stable.
Treatment overview: what double jaw surgery is
Double jaw surgery is a procedure that moves both the upper jaw (maxilla) and lower jaw (mandible) into a more balanced position. It is designed to correct skeletal problems that cannot be solved by simple bite adjustment alone.
In simple terms, the surgeon carefully cuts and repositions the jawbones, then fixes them in the new position with plates and screws. This changes the foundation of the face, not just the soft tissue. Because the jaws support the nose, lips, and lower face, even small changes in jaw position can create a noticeable improvement in facial balance.

Double jaw surgery is commonly used to address:
Long or short lower face
Protruding or recessed jaws
Facial asymmetry where one side looks different from the other
Gummy smile where too much gum shows when smiling
Open bite where the front teeth do not meet when the mouth is closed
Deep bite or crossbite that affects chewing and speaking
Jaw discomfort related to an imbalanced bite
Modern clinics in Seoul usually plan this surgery using detailed imaging such as X-rays, CT scans, and 3D facial scans. These tools allow the team to simulate how moving the jaws will change the bite and the facial profile before surgery. This planning is essential to balance function and aesthetics.
Before surgery: common concerns and reasons for considering it
Most people who consider double jaw surgery have lived with their jaw shape for many years. They often describe a mix of functional and emotional concerns.
Typical concerns before surgery include:
A long or protruding lower face that makes the profile look sharp or “stretched”
A recessed chin or weak jawline that makes the neck and jaw blend together
A gummy smile where the upper gums show widely when smiling
Facial asymmetry, such as one side of the jaw appearing lower, wider, or more forward
Difficulty biting certain foods because the front or back teeth do not meet properly
Chewing discomfort or jaw fatigue after meals
Speech difficulties related to jaw and bite position
Lack of confidence in side-profile photos or when smiling widely
Many patients have already tried bite alignment alone in the past. While this can improve how the upper and lower arches meet, it cannot fully correct a skeletal imbalance. When the underlying bone structure is the main issue, double jaw surgery is often the only way to create a true change in facial proportions and profile.
Emotionally, people often say they feel their outer appearance does not match how they feel inside. They may avoid photos, feel self-conscious in social situations, or worry that their jaw shape makes them look older, tired, or unfriendly.
After surgery: realistic improvements and what changes
After double jaw surgery, the aim is not to create a completely different face, but to bring the existing features into better harmony.

Common improvements include:
More balanced facial proportions between the upper, middle, and lower face
A smoother, more defined jawline and chin
A more attractive side profile, with better transition from nose to lips to chin
Reduced appearance of a long face or protruding mouth
Less visible gum when smiling, if a gummy smile was corrected
Improved bite contact, making it easier to chew a wide range of foods
More comfortable jaw position, which can ease strain and fatigue
Increased confidence in photos and during conversations
It is important to understand that the changes are three-dimensional. The entire lower face, including the lips, cheeks, and chin area, is affected because they all sit on the jawbones. This is very different from procedures that only change the surface, such as fillers or nose reshaping.
The final result does not appear immediately. Swelling is significant in the first weeks and then slowly decreases. Most patients see a clear change in facial shape by 1 to 3 months, but the most refined definition can take 6 to 12 months as tissues settle.
Who may consider double jaw surgery
Double jaw surgery may be considered if you:
Have a clearly protruding or recessed jaw that affects your profile
Notice that your face looks very different from the front and side views
Have difficulty biting noodles, sandwiches, or meat evenly
Often bite your cheeks or lips because of misaligned jaws
Show a lot of gum when smiling, or your upper teeth do not show enough
Have chronic jaw discomfort or fatigue after eating
Feel that your jaw shape strongly affects your confidence
A specialized plastic surgery clinic in Seoul will usually perform a detailed evaluation to confirm whether double jaw surgery is appropriate. In some cases, a single jaw procedure or other facial bone contouring may be recommended instead, or combined procedures such as chin reshaping or nose reshaping may be suggested to optimize harmony.
Step-by-step patient journey
1) Initial consultation and facial analysis
For overseas patients, the journey often begins with an online consultation. You may be asked to send clear photos of your face from the front, 45-degree angle, and side, both at rest and smiling. Some clinics also request basic medical information and previous imaging if available.
When you visit the clinic in person, the team will usually perform:
Clinical examination of your face and jaw movement
Standardized facial photos from multiple angles
X-rays and sometimes CT scans to see the bone structure
3D facial scans or simulations to analyze proportions
Bite analysis to check how your upper and lower arches meet
This step helps identify the main problems: skeletal imbalance, asymmetry, bite issues, or a combination.

2) Treatment planning with collaboration
Double jaw surgery planning often involves cooperation between the surgical team and a bite alignment specialist. Together, they decide how much to move each jaw and in which direction to achieve both functional and aesthetic goals.
Advanced software can simulate the new jaw positions and show predicted changes in profile and facial length. This is also the stage where the team discusses whether additional procedures, such as chin reshaping or nose refinement, might help create a more harmonious result.
You should be encouraged to share your main concerns: which angles you dislike, what kind of changes you hope for, and what you want to avoid. Clear communication helps align expectations with what is realistically achievable.
3) Pre-surgery preparation
Some patients need bite preparation before surgery. This is done to position the arches in a way that will match the new jaw positions. Your clinic will explain how long this may take and whether it can be coordinated with your travel schedule.
You will also go through general pre-surgery checks, such as blood tests and medical history review, to ensure it is safe to proceed under general anesthesia.
4) The surgery under general anesthesia
Double jaw surgery is performed in an operating room under general anesthesia. The surgeon usually makes incisions inside the mouth, so there are no visible external scars in most cases.
The main steps include:
Careful cutting of the upper and lower jawbones
Repositioning the jaws according to the pre-planned design
Fixing the bones with plates and screws to hold them in place
Checking the bite and facial symmetry before closing
[이미지복붙]https://contentsbox-images.s3.ap-northeast-2.amazonaws.com/transformed/e246f3c188144db6862f5f4d2b3f974f.jpg
The duration varies, but it is generally several hours. After surgery, you are moved to a recovery area and then to a hospital room.
5) Hospital stay and early recovery
Most patients stay in the hospital for a short period for close monitoring, pain control, and guidance on how to manage the new jaw position.
In the first days, you can expect:
Significant swelling of the lower face
Bruising around the cheeks and jaw area
Tightness or stiffness when trying to open the mouth
Difficulty speaking clearly
A liquid or very soft diet
The clinic staff will teach you how to keep your mouth clean, manage swelling, and take medications. Some clinics provide special cooling devices, mouth rinses, and detailed written instructions.
6) Long-term follow-up and finishing
After discharge, you will return to the clinic for regular check-ups. These visits allow the team to monitor healing, adjust your bite if needed, and confirm that the jaws are stable.
If bite finishing is required, it is usually done over several months. Follow-up imaging may be taken to compare the actual result with the planned simulation.
For overseas patients, the clinic may arrange a compact schedule of in-person visits during your stay in Korea and then continue follow-up through online consultations once you return home.

Recovery timeline in practical terms
Recovery from double jaw surgery is a gradual process. A realistic timeline is:
First 1 to 2 weeks
Swelling and bruising are at their peak. The face may look wider and rounder than expected. Eating is limited to liquids or very soft foods. Speaking can be tiring. You will need to sleep with your head elevated and follow strict hygiene instructions.
Weeks 3 to 4
Swelling begins to decrease, and bruising fades. You may transition to soft, easy-to-chew foods as allowed by your surgeon. Daily activities become more comfortable, but you still need to avoid heavy exercise or impact.
1 to 3 months
Most visible swelling improves. Friends and family will clearly notice the change in your facial shape. You can usually eat a wider range of foods, though very hard or chewy items may still be restricted. Numbness around the lips or chin often starts to improve.
6 to 12 months
Fine details of the face continue to refine as residual swelling disappears. The bite becomes more stable, and the final facial contours become apparent. Any remaining numbness often continues to improve, though this can vary.
Temporary side effects
Common temporary side effects include:
Numbness or tingling around the lips, chin, or cheeks
Difficulty opening the mouth widely
Speaking discomfort or changes in pronunciation
Increased saliva or drooling in the early days
Weight loss due to limited diet
These usually improve over time, but recovery speed differs from person to person.
Following medical instructions is essential. This includes:
Diet progression from liquids to soft foods to regular foods
Careful oral hygiene using mouth rinses and soft brushes
Avoiding smoking and alcohol during the healing period
Limiting physical activity and avoiding impact to the face
Attending all scheduled follow-up visits

Safety, risks, and how to reduce them
Like any major surgery, double jaw surgery carries risks. These may include:
Infection
Bleeding or prolonged swelling
Nerve-related numbness or altered sensation
Asymmetry or bite issues that may require adjustment
Need for revision surgery in some cases
Choosing an experienced surgical team and a clinic that focuses on facial bone procedures can help reduce these risks. Detailed preoperative planning with imaging and simulations, careful surgical technique, and strict postoperative care are all important.
As a patient, you can also contribute to safety by:
Providing accurate medical history and medication information
Following fasting and preparation instructions before surgery
Not smoking before and after surgery
Following all aftercare guidelines precisely
Reporting any unusual symptoms, such as fever, severe pain, or sudden changes in sensation
Role of a specialized plastic surgery clinic in Seoul
Seoul is known for clinics that focus on facial bone contouring and double jaw surgery. A dedicated clinic typically offers:
Customized surgical planning based on each person’s unique facial structure, not a one-size-fits-all approach
Balanced focus on functional correction of the bite and jaw joint together with aesthetic goals such as profile, symmetry, and facial length
Use of advanced imaging and 3D simulation to preview expected changes and support precise planning
Extensive before and after photo documentation so patients can understand realistic outcomes
For overseas patients, many clinics also provide language support, airport pickup options, and assistance with accommodation and scheduling.
How to evaluate before and after photos
Before and after photos are one of the most useful tools when researching double jaw surgery. To evaluate them effectively, look for:
[이미지복붙]https://contentsbox-images.s3.ap-northeast-2.amazonaws.com/transformed/af1198d9277c4423abd8fe8d7c6514dc.jpg
Natural-looking results where the person still looks like themselves, just more balanced
Improved harmony from multiple angles: front, 45-degree, and side views
Consistent quality across many cases, not just a few dramatic examples
Improved bite and jawline, not only changes in the nose or chin
Balanced facial length, with neither an overly long nor overly short lower face
Remember that individual results vary. Bone structure, skin thickness, age, and additional procedures all influence the outcome. If you see a result you like, ask whether the patient had combined treatments such as chin reshaping, nose surgery, or other facial contouring.
Online consultation and pre-visit preparation for overseas patients
Before traveling to Seoul, an online consultation can help you understand whether you are a suitable candidate and what to expect.
To prepare for an online consultation:
Take clear photos of your face from the front, both sides, and 45-degree angles, with a neutral expression and a natural smile
Prepare any previous imaging or reports related to your jaw or bite
Write down your main concerns and goals, including what you like and dislike about your profile
List your medical history, current medications, and any past surgeries
Prepare questions about the procedure, recovery time, and costs
During the consultation, the clinic can give you a preliminary opinion, suggest possible treatment options, and outline a likely timeline for your visit to Korea.
Expected Korea visit timeline
The exact schedule depends on your case, but a common structure for international patients is:
Day 1 to 2: In-person consultation, imaging, and final planning
Day 3 to 5: Pre-surgery tests and preparation
Surgery day: Operation under general anesthesia, followed by hospital admission
Postoperative days 1 to 3: Hospital stay for monitoring and early recovery
Following 1 to 2 weeks: Outpatient visits for check-ups, suture care, and guidance on diet and hygiene
Following 2 to 4 weeks: Additional follow-up visits if you remain in Korea longer
Some patients stay in Korea for several weeks after surgery to ensure stable early recovery and to attend multiple follow-up appointments before returning home.

Aftercare once you return home
After you leave Korea, maintaining communication with the clinic is important. Many clinics offer online follow-up through photos, video calls, or messaging.
You should:
Continue following the diet and activity guidelines provided at discharge
Monitor for any signs of infection or unusual changes and report them promptly
Attend any recommended local medical check-ups if advised by the clinic
Send periodic photos so the team can evaluate healing and facial changes
If you need bite finishing after returning home, the clinic can coordinate with a local specialist when possible.
Frequently asked questions
How painful is double jaw surgery?
Discomfort is expected, especially in the first few days, but modern pain control methods usually keep it manageable. Most patients describe more pressure and tightness than sharp pain.
Will my face look completely different?
The goal is improved balance, not a new identity. Friends may notice that you look more harmonious and refreshed, but you should still look like yourself.
How long before I can return to work or school?
Many patients plan 2 to 4 weeks off, depending on the nature of their work and their comfort with being seen during swelling. Remote work can sometimes be resumed earlier.
Will numbness go away completely?
Temporary numbness is common, especially in the lower lip and chin. It often improves over months, but the degree of full recovery varies from person to person.
