BSSO
Also written as: BSSO — Bilateral Sagittal Split Osteotomy
Surgical procedure that divides the mandible bilaterally to reposition the lower jaw for correction of dentofacial deformities.
Full Definition
Bilateral Sagittal Split Osteotomy is a common orthognathic surgical technique used to advance, setback, or vertically reposition the mandible. The procedure involves making controlled splits through both sides of the mandibular ramus, allowing the tooth-bearing segment to be repositioned while maintaining blood supply to the teeth. BSSO is frequently performed in conjunction with maxillary osteotomies to achieve optimal facial balance and function.
