BSSO
Also written as: BSSO — Bilateral Sagittal Split Osteotomy
Bilateral Sagittal Split Osteotomy - surgical technique for repositioning the mandible.
Full Definition
A surgical procedure used in orthognathic surgery where the mandible is split bilaterally in the sagittal plane to allow repositioning of the lower jaw. The technique involves careful dissection to preserve the inferior alveolar nerve and allows for advancement, setback, or rotation of the mandibular segments. Rigid fixation with plates and screws maintains the new position during healing. BSSO is considered the gold standard for mandibular repositioning due to its versatility and predictable healing.
