Techniques for ensuring the lateral position of the proximal segment following intraoral vertical ramus osteotomy.
Continual refinements of the surgical technique and instrumentation for the intraoral vertical ramus osteotomy have made it a preferred procedure for mandibular setback, especially in asymmetrical cases. However, there may be intraoperative difficulty in lateral positioning of the proximal segment, which is frequently trapped medially. Three techniques for lateral relocation of the medially displaced proximal segment are described. Techniques designed to prevent this medial displacement also are presented.
