Where is the medial cut made in a Bilateral Sagittal Split Osteotomy (BSSO)?

The medial cut in a Bilateral Sagittal Split Osteotomy (BSSO) is made immediately above the lingual cortex of the mandible.

This placement is crucial because it allows for adequate mobilization of the mandible while preserving critical structures such as the inferior alveolar nerve and blood supply. Making the cut immediately above the lingual cortex ensures that the osteotomy facilitates the required movement of the mandibular segments during treatment for deformities or malocclusion. Furthermore, this location helps in achieving a good stability of the bone after repositioning, promoting proper healing and reducing the risk of complications. Properly understanding the anatomy and the specific locations for these osteotomies is vital for successful surgical outcomes in OMFS procedures.
