BSSO
Also written as: BSSO — Bilateral Sagittal Split Osteotomy
Bilateral sagittal split osteotomy of the mandible used to correct jaw deformities.
Full Definition
A surgical technique involving bilateral sagittal split osteotomy of the mandible, where cuts are made through the mandibular ramus and body to allow repositioning of the tooth-bearing segment. This procedure is commonly used in orthognathic surgery to advance or set back the lower jaw, correct asymmetries, and treat malocclusion. The technique allows for large movements while preserving the inferior alveolar nerve and maintaining adequate bone contact for healing.
Usage
Usage note: Always capitalize when abbreviated; may be written as 'bilateral sagittal split osteotomy' in formal documentation.
