Mandible Advancement/Reduction

Mandibular advancement or reduction surgery is performed to correct jaw size and position when the lower jaw (mandible) is either too far back (retrognathia) or too far forward (prognathism). These conditions can lead to problems with bite alignment (malocclusion), facial symmetry, breathing, chewing, and overall appearance.

This corrective jaw surgery, also known as orthognathic surgery, helps bring the jaws, teeth, and facial profile into better alignment — improving both function and aesthetics.

What We Do

Our team of oral & maxillofacial surgeons carefully evaluates the patient’s facial structure, bite, and airway. We use advanced imaging and planning tools to perform:

  • Mandibular Advancement Surgery – Moving the lower jaw forward

  • Mandibular Reduction Surgery – Repositioning or reshaping an overly prominent lower jaw

Both procedures may be done in combination with orthodontic treatment for optimal results.

Who Needs This Surgery?

  • Individuals with receding or protruding lower jaw

  • Patients with bite problems like underbite, open bite, or crossbite

  • Those with obstructive sleep apnea due to jaw positioning

  • People with facial asymmetry or long face/short chin

  • Individuals unhappy with their jawline appearance

Benefits of Mandible Surgery

  • Corrects facial imbalance and jaw alignment

  • Improves chewing, speech, and breathing

  • Enhances facial aesthetics and self-confidence

  • Resolves chronic jaw pain (TMJ) in some cases

  • Increases airway space (helpful in sleep apnea)

Treatment Process

  1. Pre-surgical orthodontics (6–12 months in most cases)

  2. Surgical planning using 3D scans and bite models

  3. Surgery under general anesthesia — involves bone cutting and repositioning

  4. Fixation using plates and screws for stabilization

  5. Recovery period with a soft diet and follow-up care

  6. Post-surgical orthodontics for fine-tuning bite alignment (if needed)

Recovery & Aftercare

  • Swelling and numbness are common and gradually improve

  • Return to daily activities in 1–2 weeks (depends on case)

  • Full recovery may take 6–8 weeks

  • Follow-up includes oral hygiene, jaw exercises, and diet guidance

Risks & Considerations

  • Temporary numbness in lips or chin

  • Infection or relapse (rare)

  • Bite adjustments may take time post-surgery

  • Psychological readiness is important for major facial change
