Overview:
Orthognathic (jaw) surgery is a corrective surgical procedure designed to realign and reposition the jaws when orthodontic treatment alone cannot resolve functional or aesthetic issues. It is typically performed to correct significant jaw discrepancies, such as an overbite, underbite, open bite, or facial asymmetry. The surgery aims to improve chewing, speaking, breathing, and overall facial harmony. Orthognathic surgery is often done in collaboration with orthodontic treatment, ensuring proper alignment of the teeth and jaws for long-term stability.

What to Expect:

Symptoms/Indications:
Patients who may benefit from orthognathic surgery often experience:

• Difficulty biting, chewing, or swallowing food
• Chronic jaw or temporomandibular joint (TMJ) pain
• Speech problems related to jaw alignment
• Breathing difficulties, such as sleep apnea
• Noticeable facial imbalance, receding chin, or protruding jaw

Diagnosis:
Evaluation involves a multidisciplinary approach with orthodontists and oral and maxillofacial surgeons. Diagnostic steps may include:

• Dental and facial X-rays or CT scans
• 3D imaging and digital models of teeth and jaws
• Orthodontic assessment for bite and tooth alignment
• Sleep studies in cases of suspected airway obstruction

Treatment:
Treatment is carefully planned and often staged:

• Pre-surgical orthodontics: Braces are usually placed months before surgery to align the teeth.
• Surgical procedure: The surgeon makes precise cuts in the jawbones, repositions them, and stabilizes them with plates, screws, or wires. The surgery may involve the upper jaw (maxilla), lower jaw (mandible), or both.
• Post-surgical orthodontics: Braces remain for several months after surgery to fine-tune alignment.
• Recovery care: Includes dietary adjustments (soft or liquid diet), pain management, and physical therapy exercises to restore full function.

What to Consider:

Risk Factors & Complications:

• Bleeding, infection, or delayed healing
• Temporary or permanent numbness in the lips, cheeks, or tongue due to nerve involvement
• Relapse of jaw position in rare cases
• TMJ dysfunction if alignment does not stabilize
• Emotional or psychological adjustment to altered facial appearance

Prevention / Early Management:
Many minor bite issues can be managed with orthodontics alone. Early orthodontic intervention in growing children may reduce the need for surgical correction later. However, for adults with severe jaw discrepancies, surgery is often the definitive solution.

Progression:
Without treatment, severe jaw misalignments can worsen over time, leading to difficulties with chewing, digestion, chronic pain, sleep problems, and reduced self-confidence. Surgical correction not only resolves functional problems but also provides long-term improvements in oral health and quality of life.

Other Information:

Surgical Techniques:

• Le Fort Osteotomy: For repositioning the upper jaw.
• Bilateral Sagittal Split Osteotomy (BSSO): For advancing or setting back the lower jaw.
• Genioplasty: A chin surgery often performed alongside jaw surgery for balanced aesthetics.

Recovery Timeline:

• Initial healing: 6–8 weeks
• Complete recovery: Up to 12 months for full bone healing and orthodontic adjustments

Conclusion:
Orthognathic (jaw) surgery is a highly specialized procedure that addresses both functional and aesthetic concerns of the jaws and teeth. By improving chewing, speech, breathing, and facial balance, it significantly enhances overall quality of life. With careful diagnosis, treatment planning, and post-surgical care, patients can expect lasting results and improved oral health.
