Double Jaw Surgery: What to Expect, Costs, and Recovery

Double jaw surgery, also known as bimaxillary orthognathic surgery, is a comprehensive procedure that moves both the upper jaw (maxilla) and lower jaw (mandible) to improve facial balance, bite function, and in many cases, airway and breathing. This transformative surgery can address both functional and aesthetic concerns that significantly impact quality of life.

What Is Double Jaw Surgery?

Double jaw surgery is a complex oral and maxillofacial procedure that involves surgically repositioning both the upper and lower jaws to achieve optimal function, aesthetics, and airway health. Unlike single-jaw procedures, this comprehensive approach allows for complete facial harmony and maximum functional improvement.

The surgery involves making precise cuts in the jawbones, repositioning them according to a detailed surgical plan, and securing them with titanium plates and screws. The entire procedure is performed from inside the mouth, leaving no external scars.

Conditions Treated by Double Jaw Surgery

Double jaw surgery is often the solution for complex cases that cannot be adequately addressed through orthodontics alone:

Bite Problems

• Severe underbites: Lower jaw significantly protrudes beyond upper jaw
• Severe overbites: Upper jaw extends far beyond lower jaw
• Open bites: Front teeth don't meet when back teeth are together
• Crossbites: Misalignment of upper and lower jaw widths

Facial Asymmetry

• Uneven jaw growth
• Facial imbalance from birth defects
• Trauma-related deformities
• Congenital conditions affecting jaw development

Airway and Breathing Issues

• Obstructive sleep apnea
• Upper Airway Resistance Syndrome (UARS)
• Chronic mouth breathing
• Narrow airways affecting sleep quality

Functional Problems

• Difficulty chewing or biting
• Speech impediments
• TMJ disorders
• Chronic jaw pain

Why People Choose Double Jaw Surgery

While some pursue jaw surgery primarily for facial harmony, many are motivated by serious health and functional concerns:

Health-Related Motivations

• Breathing improvement: Opening restricted airways
• Sleep quality: Reducing sleep apnea and UARS symptoms
• Pain relief: Addressing TMJ and chronic jaw pain
• Functional restoration: Improving chewing, speaking, and swallowing

Quality of Life Benefits

• Enhanced facial balance and aesthetics
• Improved self-confidence
• Better sleep leading to increased energy
• Reduced chronic pain and discomfort
• Improved oral function

The Double Jaw Surgery Process

Understanding the complete process helps set realistic expectations:

Pre-Surgical Phase (6-18 months)

1. Comprehensive evaluation: Including sleep studies, airway analysis, and facial imaging
2. Pre-surgical orthodontics: Aligning teeth within each jaw
3. Surgical planning: 3D imaging and virtual surgical planning
4. Medical clearance: Ensuring optimal health for surgery

Surgical Planning Technology

Modern jaw surgery utilizes advanced technology:

• 3D CT scans: Detailed bone structure analysis
• Virtual surgical planning: Computer-guided surgical simulation
• Custom surgical guides: Ensuring precise jaw positioning
• Predictive imaging: Showing expected post-surgical results

The Surgery Day

Duration: Typically 3-6 hours depending on complexity

Procedure steps:

1. General anesthesia: Ensuring complete comfort and safety
2. Upper jaw surgery: Repositioning the maxilla
3. Lower jaw surgery: Repositioning the mandible
4. Additional procedures: Chin surgery (genioplasty) if needed
5. Securing with hardware: Titanium plates and screws
6. Closure: Suturing incisions inside the mouth

Hospital Stay

• Full function: Near-normal jaw movement
• Final results: Becoming apparent

6-12 Months: Complete Recovery

• Final healing: Bone completely healed
• Orthodontic completion: Final bite refinement
• Full function: Complete return to normal activities
• Final results: Stable, long-term outcome

Double Jaw Surgery Costs

The financial investment in double jaw surgery varies significantly based on multiple factors:

Cost Breakdown (USD)
