Double Jaw Surgery

Double Jaw Surgery (Two-Jaw Surgery) in Seoul

Reshape Your Jaw for Function and Aesthetics with Advanced Orthognathic Surgery



Double jaw surgery, also known as two-jaw surgery or bimaxillary osteotomy, is a transformative facial bone procedure that corrects both functional and cosmetic issues related to jaw alignment. It involves surgical repositioning of both the upper (maxilla) and lower (mandible) jaws to improve bite alignment, breathing, and facial harmony.

In Seoul, this procedure is performed by highly experienced maxillofacial and plastic surgeons using cutting-edge 3D simulation and advanced surgical planning. It is often chosen by individuals with severe jaw misalignment, sleep apnea, facial asymmetry, or those seeking a dramatic change in facial structure.

What Is Double Jaw Surgery?

Double jaw surgery involves modifying the positions of both the upper and lower jaws. Unlike cosmetic-only procedures, this surgery addresses both aesthetic balance and functional improvement—such as fixing an underbite, overbite, open bite, or breathing issues due to a recessed jaw.

This procedure is ideal for:

  • Severe jaw misalignment (malocclusion)
  • Protruding or recessed jaw
  • Facial asymmetry
  • Congenital skeletal imbalance
  • Snoring or sleep apnea caused by jaw positioning
  • Patients seeking a permanent transformation of their lower face


How It Works

Performed under general anesthesia, the procedure typically involves:

  1. Pre-surgical orthodontic treatment to align the teeth
  2. Le Fort I osteotomy to reposition the upper jaw (maxilla)
  3. Bilateral sagittal split osteotomy (BSSO) to reposition the lower jaw (mandible)
  4. Use of plates and screws to secure the repositioned bones
  5. Optional genioplasty or facial contouring for balance and refinement

Advanced 3D simulation is often used to preview results and create a precise surgical plan. The operation generally takes 3 to 5 hours.


Recovery and Aftercare

  • Hospital stay: 2–3 days typically
  • Initial swelling: Significant in the first week, gradually reduces
  • Diet: Liquid or soft food for 2–4 weeks
  • Activity: Avoid strenuous activity for 4–6 weeks
  • Orthodontic treatment: Continued for several months after surgery
  • Full recovery: 3–6 months, with long-term results being permanent



Risks and Considerations

While double jaw surgery is safe in the hands of an experienced surgeon, it is a complex procedure. Possible risks include:

  • Nerve numbness in the chin or lips
  • Bleeding or infection
  • Bone relapse or healing asymmetry
  • TMJ (jaw joint) discomfort
  • Extended recovery time

Proper preoperative diagnosis, patient compliance, and skilled surgical execution greatly minimize these risks.

Sliding Genioplasty vs. Chin Implants

Option Description Pros Cons
Sliding Genioplasty Repositions your natural chin bone Natural, permanent, customizable Invasive, recovery required
Chin Implants Synthetic implant added to chin Less invasive, quicker recovery Risk of shifting or rejection

👉 Sliding genioplasty is ideal for patients seeking long-term, bone-based correction rather than surface enhancement.
