Corrective jaw surgery in Westchester and New York City

Corrective jaw surgery, also called orthognathic surgery, repositions the upper jaw, lower jaw or chin when braces alone can't fix the bite. It can improve chewing, speech, breathing and facial balance. Dr. Benichou completed fellowship training in orthognathic surgery, and treatment is planned together with your orthodontist.

Who it helps

Signs you may need jaw surgery

Jaws can grow unevenly, or end up out of position after an injury or a condition present from birth. Common signs include:

  • An underbite, overbite, open bite or crossbite
  • Trouble chewing, biting or swallowing
  • Lips that don't close without strain
  • A receding chin or a protruding lower jaw
  • A face that looks uneven from the front or side
  • Mouth breathing or sleep apnea tied to jaw position
  • Excess tooth wear, or jaw pain linked to the bite
  • Chronic jaw joint pain and headaches

Braces or surgery

When braces aren't enough

If only the teeth are out of place, braces can fix the bite. When the jaws themselves are out of position, moving the teeth can't fully correct it, and surgery moves the bone instead.

Jaw surgery is usually done once facial growth has finished, typically in the late teens or later. Your orthodontist and surgeon decide together whether surgery is needed and when.

Procedures

Types of corrective jaw surgery

Incisions are made inside the mouth, so there are usually no visible scars.

Upper jaw surgery

Le Fort I osteotomy

The upper jaw is moved forward, back, up or down and held in its new position with small plates and screws.

Lower jaw surgery

Bilateral sagittal split osteotomy

The lower jaw is split on both sides behind the molars, then moved forward or back to line up with the upper jaw.

Chin surgery

Genioplasty

The chin bone is moved to balance it with the rest of the face, either on its own or together with jaw surgery.

Double-jaw surgery

Upper and lower jaw together

Both jaws are moved in the same operation, often for larger corrections or to open the airway in sleep apnea.

The process

From consultation to final bite

  1. Visit

    Consultation

    An exam, photos and X-rays, and a conversation about your goals with you and your orthodontist.

  2. Braces

    Orthodontics before surgery

    Your orthodontist lines up the teeth on each jaw so they fit together once the jaws are moved. This can take from about six months to a few years.

  3. Planning

    3D surgical planning

    A CT scan and dental scans feed virtual surgical planning, which maps each movement in advance and produces custom splints used during surgery.

  4. Surgery

    Surgery day

    Surgery is done in the hospital under general anesthesia, usually followed by a 1–2 night stay.

  5. Finish

    Orthodontics after surgery

    Your orthodontist fine-tunes the bite, then you switch to a retainer.

Recovery

Recovery timeline

Typical ranges. Recovery varies with the type of surgery and the person.

First few days
Swelling is at its peak, usually around day two or three. You start on liquids, and pain is managed with medication. A humidifier and nasal spray help with congestion.
Weeks 1–6
Your diet moves to soft and puréed foods, and elastics may guide the bite. Many people return to school or desk work within two to three weeks.
About 6 weeks
Initial bone healing is complete. Most people go back to a regular diet and normal activity once cleared.
Months 3–12
Remaining swelling fades. Numbness in the lip or chin is common after lower jaw surgery and usually improves over several months. Complete healing takes about 9–12 months.

Questions

Corrective jaw surgery FAQ

Will my jaws be wired shut?

Usually not. Small plates and screws hold the bones in place, and rubber bands guide the bite while it heals.

When can I eat normally again?

Most people return to a regular diet about six to seven weeks after surgery, once the bone has healed.

Will my face look different?

Moving the jaws changes facial balance, usually toward a more even profile. 3D planning lets the surgeon map the expected changes before surgery.

Is jaw surgery covered by insurance?

It depends on your plan. Surgery that corrects a functional problem with chewing, speech or breathing is often considered medically necessary, so check with your insurer before surgery.
