“What are Important Landmarks in the Bilateral Sagittal Split Osteotomy of Orthognathic Surgery?”

7.1.24 Quick Review #164 - #surgery #surgeon #doctorgallagher #oralsurgery #oralsurgeon #omfs #dentist #dentistry #dental #bsso #bilateralsagittalsplit #osteotomy #orthognathic The bilateral sagittal split osteotomy (BSSO) is a common surgical procedure used to correct mandibular deformities. Important anatomical landmarks for a BSSO include: 1. Ramus: The vertical part of the mandible. The osteotomy is typically initiated here. 2. Mandibular Canal: Contains the inferior alveolar nerve. The osteotomy is planned to avoid damage to this canal and the nerve within. 3. Lingula: A bony projection on the medial aspect of the ramus. It serves as a key reference point for the horizontal cut of the osteotomy. 4. Oblique Ridge: Located on the lateral aspect of the mandible. The osteotomy often extends down this ridge. 5. Inferior Border of the Mandible: The lower edge of the mandible. Care is taken to avoid fractures or undue stress in this area. 6. Angle of the Mandible: The posterior region where the ramus meets the body of the mandible. The osteotomy line usually extends around this area. 7. Mental Foramen: Contains the mental nerve, which must be avoided to prevent sensory disturbances in the lower lip and chin. References: 1. AO Foundation. (n.d.). BSSO - Obwegeser/Dal Pont.
