What Is Double Jaw Surgery?
Also known as orthognathic surgery or two jaw surgery
Double jaw surgery is a corrective surgical procedure performed to reposition both the upper jaw (maxilla) and lower jaw (mandible) to achieve better alignment, functionality, and aesthetics. This procedure is medically referred to as bimaxillary osteotomy or orthognathic surgery and is typically recommended for patients with severe jaw misalignments that cannot be corrected by braces or aligners alone.
Unlike single jaw surgery—which addresses either the upper or lower jaw—double jaw surgery simultaneously adjusts both jaws, allowing for a more comprehensive correction of functional and cosmetic issues. This surgical approach is often used to correct conditions such as open bites, underbites, overbites, jaw asymmetry, and even sleep apnea. In some cases, patients may also undergo chin surgery (genioplasty) during the same procedure to enhance facial harmony.
How Double Jaw Surgery Works (In Simple Terms)
The surgery is done under general anesthesia and typically takes 3 to 6 hours, depending on the complexity. During the procedure, the surgeon will:
- Cut the bones of both the upper and lower jaws using specialized surgical tools.
- Reposition the jaws into the correct alignment.
- Secure the new positions using titanium plates and screws.
- Close the incisions with dissolvable sutures.
Most of the incisions are made inside the mouth, which means there are no visible scars after recovery.
Medical Terminology and Techniques Involved
| Medical Term | Description |
|---|---|
| Le Fort I Osteotomy | Repositions the upper jaw (maxilla) |
| Bilateral Sagittal Split Osteotomy (BSSO) | Repositions the lower jaw (mandible) |
| Genioplasty | Optional chin surgery for enhanced symmetry |
These procedures are often custom-planned using 3D imaging and digital modeling, ensuring that the movements are precise and tailored to each patient’s unique facial structure.
Why This Procedure Is Sometimes Necessary
Many patients who undergo double jaw surgery have tried orthodontic solutions that couldn’t fully address their concerns. When the skeletal structure is severely misaligned, surgery becomes the only long-term, stable solution. As Dr. William Proffit, a pioneer in modern orthodontics, stated:
“Orthognathic surgery, when combined with orthodontics, allows for the comprehensive correction of both dental and skeletal imbalances, providing results that are both functional and aesthetic.“

What does double jaw surgery do?
Double jaw surgery repositions both the upper and lower jaws to correct functional issues like bite problems and cosmetic concerns such as facial asymmetry.
Is double jaw surgery the same as orthognathic surgery?
Yes. Orthognathic surgery is the medical term for corrective jaw surgery, and “double jaw surgery” refers specifically to the adjustment of both jaws.
Can double jaw surgery change your face?
Yes, it can significantly improve facial structure by enhancing jawline definition and correcting asymmetry.
Who Needs Double Jaw Surgery?
Understanding when orthognathic (two jaw) surgery becomes necessary
Not everyone with a bite problem or crooked teeth needs double jaw surgery, but for some individuals, this procedure is the only effective solution. It’s typically recommended when there’s a significant misalignment between the upper and lower jaws that can’t be corrected through orthodontic treatment alone.
This type of misalignment is often skeletal, meaning the problem lies in the bone structure, not just the teeth. Left untreated, these issues can cause long-term problems with chewing, speaking, breathing, facial balance, and even mental well-being due to appearance-related concerns.
Medical Conditions That May Require Double Jaw Surgery
Here are the most common medical and functional reasons people undergo double jaw surgery:
1. Severe Overbite or Underbite
- The upper jaw significantly overlaps (overbite) or sits behind (underbite) the lower jaw.
- Causes difficulties in biting, chewing, and speaking.
- Can strain the jaw joints and lead to TMJ disorders.
2. Open Bite
- A condition where the upper and lower teeth don’t meet when the mouth is closed.
- Can severely affect eating and speech.
- Often associated with tongue thrusting or mouth breathing habits in childhood.
3. Crossbite
- Misalignment where the upper teeth bite inside the lower teeth.
- May cause asymmetrical jaw growth and uneven tooth wear.
4. Sleep Apnea or Breathing Disorders
- Double jaw surgery can expand the airway and improve oxygen flow during sleep.
- Often recommended for patients with obstructive sleep apnea (OSA) that hasn’t responded to CPAP or other non-invasive treatments.
5. Jaw Asymmetry or Facial Imbalance
- One side of the jaw grows more than the other, causing crooked smiles or shifts in facial symmetry.
- May lead to chronic pain, poor self-esteem, and difficulties with jaw function.
6. Speech Impediments
- Severe jaw misalignment can interfere with articulation, especially for sounds that require precise tongue placement like “s,” “f,” and “th.”
Cosmetic or Aesthetic Reasons for Two Jaw Surgery
Many patients also choose double jaw surgery for cosmetic enhancement, even if they don’t suffer from major functional issues. Correcting jaw proportions can make a dramatic difference in overall facial appearance.
Aesthetic improvements include:
- A more defined jawline
- A balanced profile (especially from the side)
- Correction of a “gummy smile”
- Enhanced chin projection and facial symmetry
Some people also seek this surgery to address what’s called the “long face syndrome”, where excessive vertical jaw growth gives the face a lengthened, unbalanced look. In these cases, double jaw surgery can shorten the mid-face and reposition the jaw for a more harmonious facial structure.
“I always hated my side profile and never realized my jaw was the problem,” says a real patient on Reddit. “After two jaw surgery, my breathing improved, I can eat properly, and I finally love how I look in photos.”
Psychological and Quality of Life Considerations
It’s not just about form and function—people often seek out orthognathic surgery because the problems impact their confidence and quality of life. Living with a visibly misaligned jaw or an unbalanced facial structure can contribute to:
- Low self-esteem
- Social anxiety
- Avoidance of smiling or speaking in public
In these cases, double jaw surgery can be life-changing, both emotionally and physically.
At a Glance: Who May Need Double Jaw Surgery
| Symptom/Condition | Likely Need for Surgery? |
|---|---|
| Severe overbite/underbite | ✔️ Highly likely |
| Jaw-related sleep apnea | ✔️ Often required |
| Facial asymmetry | ✔️ Often recommended |
| Cosmetic concern only | ✔️ Possible, if severe |
| Mild orthodontic misalignment | ❌ Usually not needed |
| Temporomandibular joint (TMJ) pain | ✔️ May benefit |
Answer Engine Optimization FAQs
Who is a good candidate for double jaw surgery?
Anyone with significant jaw misalignment, especially when orthodontics alone can’t correct the issue, may be a good candidate. This includes people with bite problems, sleep apnea, or facial asymmetry.
Can double jaw surgery fix an underbite or overbite?
Yes. Double jaw surgery is one of the most effective ways to permanently fix a severe overbite or underbite by repositioning both jaws for proper alignment.
Is jaw surgery only for cosmetic reasons?
No. While it can dramatically improve facial appearance, the primary goal of jaw surgery is to improve function, such as chewing, speaking, and breathing.
Signs You May Be a Candidate for Corrective Jaw Surgery
If you’re wondering whether you’re a suitable candidate for double jaw surgery, it’s essential to recognize the signs that go beyond just crooked teeth or an uneven smile. Many people live with chronic discomfort, functional issues, or cosmetic concerns related to jaw misalignment without realizing that surgery might be the long-term solution.
This section outlines both obvious and subtle signs that your jaw problems could require more than orthodontics and why two jaw surgery, or orthognathic surgery, might be necessary to improve your quality of life.
1. Chronic Jaw Pain or TMJ Disorder
One of the most common indicators that you might need double jaw surgery is persistent jaw pain, especially around the temporomandibular joint (TMJ)—the hinge that connects your jaw to your skull. If the upper and lower jaws do not align correctly, it can strain this joint, leading to:
- Clicking or popping when opening your mouth
- Difficulty chewing tough foods
- Frequent headaches
- Jaw locking or stiffness
Over time, untreated TMJ disorders can worsen, leading to limited jaw mobility and even damage to the joint structure.
2. Breathing Issues or Sleep Apnea
Another red flag is difficulty breathing while sleeping, which may point to obstructive sleep apnea (OSA). If your jaws are positioned too far back (a condition called retrognathia), they can cause the airway to collapse during sleep.
According to the American Academy of Sleep Medicine:
“Maxillomandibular advancement surgery (MMA), a type of double jaw surgery, is one of the most effective surgical treatments for moderate to severe sleep apnea.“
Signs of sleep-disordered breathing include:
- Loud, chronic snoring
- Waking up gasping or choking
- Daytime fatigue and poor concentration
- High blood pressure related to poor sleep quality
3. Difficulty Chewing, Biting, or Swallowing
If you consistently struggle to chew certain foods or notice that your teeth don’t meet properly, it’s a potential sign of a skeletal jaw issue. Misaligned jaws can cause problems like:
- Overcompensation by facial muscles during chewing
- Unbalanced bite pressure leading to tooth wear
- Difficulty biting into hard or chewy foods
Orthodontics may improve tooth alignment, but if the underlying bone structure is off, only jaw surgery can fix the core problem.
4. Speech Problems or Lisping
Speech is closely connected to the alignment of the teeth and jaws. A severely misaligned bite can affect the ability to pronounce certain sounds correctly. People with jaw alignment issues may struggle with:
- Lisping or slurring certain consonants
- Nasal-sounding speech
- Difficulty controlling tongue position when speaking
Corrective jaw surgery can help by properly aligning the jaws and repositioning the oral structures involved in speech production.
5. Chronic Mouth Breathing or Snoring
Jaw misalignment often results in poor tongue posture and restricted nasal airflow, which causes mouth breathing. This can lead to:
- Dry mouth and bad breath
- Increased risk of gum disease and cavities
- Reduced oxygen intake during sleep
Persistent mouth breathing, especially in children or teens, may be an early sign that double jaw surgery could be necessary later in life if left untreated.
6. Facial Asymmetry or Unbalanced Profile
If your facial structure looks uneven, it could be due to abnormal jaw growth patterns. These may include:
- One side of the jaw growing longer than the other
- A receding or overly prominent chin
- A long mid-face or flat cheekbones
Double jaw surgery can restore symmetry and balance to the face, which is especially important for people who feel self-conscious about their appearance.
7. Emotional or Psychological Distress About Appearance
While this isn’t a medical necessity, some patients experience deep psychological stress due to their facial structure. Feelings of:
- Low self-esteem
- Avoidance of social situations
- Constant comparison to others
…can all stem from jaw-related aesthetic concerns. In such cases, a consultation with an oral and maxillofacial surgeon can help determine whether surgery could improve both physical function and emotional well-being.
Checklist: Signs You May Be a Candidate for Double Jaw Surgery
| Sign/Symptom | Possible Link to Jaw Misalignment |
|---|---|
| Chronic jaw pain | ✅ Yes – TMJ disorder or bite misalignment |
| Snoring or sleep apnea | ✅ Yes – Recessed jaw or airway blockage |
| Trouble chewing or biting | ✅ Yes – Improper jaw alignment |
| Lisp or unclear speech | ✅ Yes – Affected tongue and palate positioning |
| Uneven face or jawline | ✅ Yes – Asymmetrical jaw growth |
| Chronic mouth breathing | ✅ Yes – Narrow airway or low tongue posture |
| Low self-confidence due to facial features | ✅ Yes – Often linked to structural imbalance |
Answer Engine Optimization FAQs
How do I know if I need double jaw surgery?
You may need double jaw surgery if you suffer from a significant bite problem, facial asymmetry, jaw pain, breathing issues, or speech difficulties that orthodontic treatment alone cannot resolve.
Can jaw surgery help with TMJ pain?
Yes. If your TMJ pain is caused by jaw misalignment, corrective jaw surgery can realign the bones, reduce strain, and potentially relieve the pain permanently.
Is chronic snoring a sign I need jaw surgery?
Chronic snoring, especially when associated with sleep apnea, can be a sign that your jaw position is obstructing your airway. Double jaw surgery may help by expanding the airway space.
The Double Jaw Surgery Process (Step-by-Step)
What to expect before, during, and after two jaw surgery
Understanding the entire double jaw surgery process helps reduce anxiety and prepares patients for what lies ahead. This section breaks down the typical stages—from consultation to full recovery—so you know exactly what to expect.
1. Initial Consultation and Evaluation
The journey starts with a thorough evaluation by an oral and maxillofacial surgeon, often in collaboration with an orthodontist. During this stage:
- Your medical and dental history will be reviewed.
- Detailed photographs of your face and teeth are taken.
- X-rays and 3D CT scans capture precise images of your jaw bones.
- Impressions or digital scans of your teeth are made.
This information is used to assess whether double jaw surgery is the best option and to create a customized surgical plan.
2. Pre-Surgical Orthodontics
Before surgery, patients typically undergo orthodontic treatment (braces or aligners) for 12 to 18 months. This phase:
- Aligns the teeth within each jaw.
- Prepares the bite for surgical repositioning.
- Helps ensure optimal post-surgery alignment and stability.
It’s important to note that your bite may feel worse before surgery—that’s normal. The goal is to set up your teeth to fit together properly after the jaws are moved.
3. The Surgery Day
Double jaw surgery is performed in a hospital or outpatient surgical center under general anesthesia and usually lasts between 3 to 6 hours.
Surgical steps include:
- Making incisions inside the mouth to avoid visible scars.
- Performing a Le Fort I osteotomy to reposition the upper jaw.
- Performing a bilateral sagittal split osteotomy (BSSO) to adjust the lower jaw.
- Optional genioplasty for chin reshaping.
- Fixing the jaws in their new positions with titanium plates and screws.
After surgery, the jaws may be temporarily wired or elastically banded to stabilize the bite.
4. Hospital Stay and Immediate Recovery
Most patients stay in the hospital 1 to 3 days after surgery for monitoring. Common post-op experiences include:
- Swelling and bruising around the face and neck.
- Mild to moderate pain managed with prescribed medication.
- A liquid or soft diet initially to protect the surgical site.
- Instructions on oral hygiene and how to manage swelling.
Your surgeon will provide detailed guidelines on care and signs of potential complications.
5. Post-Surgical Orthodontics and Healing
Once healing has progressed (usually 6 to 8 weeks), your orthodontist will:
- Remove any wires or bands.
- Continue adjusting your braces to fine-tune the bite.
- This phase may last another 6 to 12 months.
Full bone healing takes about 3 to 6 months, but most patients feel significantly better within weeks.
6. Long-Term Results and Follow-Up
Patients typically experience:
- Improved bite and jaw function.
- Enhanced facial symmetry and profile.
- Better breathing and sleep quality if airway issues were present.
Regular follow-ups with your surgical and orthodontic team ensure the results are stable and any adjustments are made promptly.

A primary benefit is restoring proper jaw alignment, which improves how your upper and lower teeth fit together. This helps:
- Enhance chewing efficiency and comfort.
- Reduce abnormal wear on teeth.
- Decrease jaw muscle strain and jaw joint (TMJ) pain.
- Improve speech clarity and reduce lisping caused by jaw misalignment.
2. Relief from Breathing and Sleep Issues
Patients with obstructive sleep apnea or airway obstruction often experience dramatic improvements. Double jaw surgery:
- Opens the airway by advancing the jaws forward.
- Reduces snoring and episodes of apnea during sleep.
- Improves oxygen levels and overall sleep quality.
- Decreases daytime fatigue and related health risks.
A 2016 study in the Journal of Oral and Maxillofacial Surgery showed that maxillomandibular advancement surgery has a success rate of over 85% in treating moderate to severe sleep apnea.
3. Enhanced Facial Appearance and Symmetry
By repositioning the jaws, the surgery corrects facial imbalances such as:
- A receding chin or protruding jaw.
- Uneven jawlines or asymmetry.
- Improves the profile and harmony of facial features.
Many patients report a boost in confidence and self-esteem after their facial aesthetics improve.
4. Long-Term Stability
Because the surgery realigns the bone structure, the results tend to be stable long-term when combined with proper orthodontics and post-surgical care.
5. Psychological and Emotional Benefits
Improved function and appearance can lead to:
- Increased self-confidence.
- Reduced social anxiety related to facial appearance.
- Better quality of life and emotional wellbeing.
