PROCEDURE : SURGICAL

What is BSSO (Bilateral Sagittal Split Osteotomy) surgery?

  • Bilateral sagittal split osteotomy (BSSO) is a corrective jaw surgery that involves repositioning your lower jaw (mandible). 
  • During the procedure, your lower jaw is separated and then moved either forward or backward (bilaterally) and reattached in a more balanced and functional position.
  • It may be used to correct a large overbite, enlarged lower jaw or to rotate the jaw slightly for better facial asymmetry. 

Sometimes, this surgery is done at the same time as upper jaw surgery (Le Fort osteotomy) or chin surgery (sliding genioplasty).

The procedure is performed intraorally, which means there are no visible scars on the face.


Who is a candidate for BSSO surgery?

  • Suitable candidates for BSSO surgery include individuals with:
    • Abnormal bite patterns like overbite, underbite, or crossbite.
    • Facial disproportion or asymmetry.
    • Functional issues such as difficulty chewing, speaking, or breathing.
    • A positive outlook and realistic expectations about the surgery.

What conditions can BSSO surgery treat?

  • BSSO surgery can address:
    • Bite discrepancies including overbite, underbite, and crossbite.
    • Speech and breathing issues caused by jaw misalignment.
    • Facial imbalances like asymmetry or underdeveloped jaws.
    • Obstructive sleep apnea related to jaw structure.

How is BSSO surgery performed?

  • BSSO surgery is performed under general anaesthesia.
    • The surgeon makes incisions inside the mouth to access the lowerlower jawbone.
    • The jaw is carefully separated and repositioned using screws or plates to secure it in its new position.
    • The incisions are closed with dissolvable stitches, and no external scars are left.

What can I expect during BSSO surgery?

  • During BSSO surgery, the surgeon will:
    • Use advanced techniques such as 3D planning before the surgery.
    • Realign the jaw to correct any issues with bite or facial symmetry.
    • Employ bone screws or plates to stabilize the jaw in its new position.

What is the recovery process after BSSO surgery?

  • Recovery from BSSO surgery typically includes:
    • A hospital stay of 2 to 4 days for monitoring.
    • Swelling and numbness that peak within the first three weeks.
    • A soft diet and careful jaw movement for several weeks.
    • Full recovery can take up to 3 months, with ongoing orthodontic care.

How long does BSSO surgery take?

  • BSSO surgery duration varies but generally takes:
    • 2 to 5 hours depending on the complexity of the case.
    • General anaesthesia is used, so the patient remains unconscious during the procedure.

What are the risks of BSSO surgery?

  • Risks associated with BSSO surgery include:
    • Infection at the surgical site.
    • Nerve damage leading to numbness in the lower lip or cheeks.
    • Improper healing of the bones or need for additional surgery.
    • Jaw joint issues and potential relapse of the original problem.

How can BSSO surgery improve quality of life?

  • BSSO surgery can enhance quality of life by:
    • Correcting bite issues that affect chewing, speaking, and breathing.
    • Improving facial symmetry and overall appearance.
    • Reducing pain and discomfort associated with jaw misalignment.
    • Enhancing self-esteem through improved facial aesthetics.

What is the role of orthodontics in BSSO surgery?

  • Orthodontic treatment is essential before and after BSSO surgery.
    • Pre-surgery orthodontics helps align the teeth for optimal surgical outcomes.
    • Post-surgery orthodontics may involve braces or rubber bands to ensure proper healing and alignment of the jaw.
