The Intraoral Vertical Ramus Osteotomy

  • Rebeka G. SilvaEmail author


The intraoral vertical ramus osteotomy (IVRO) has a distinct advantage over other TMJ surgeries; the joint capsule and intracapsular structures are preserved, and the surgery has a low complication rate. For selected patients with symptomatic anterior disc dislocation, the IVRO is a classic operation that can unload the joint as well as reposition it more favorably under the disc. The new condylar position can be characterized as an increase in the superior joint space dimension and a slightly more anterior angulation of the joint head. Patient selection is important, due to the need to maintain control over the occlusion through the use of maxillomandibular fixation for several weeks.
