下顎枝垂直骨切り術施行後の顎関節前方脱臼を防ぐための一工夫 An approach to prevent dislocation of proximal bony fragments after intraoral vertical ramus osteotomy
Intraoral vertical ramus osteotomy (IVRO) has far less adverse effects on the postoperative function of the temporomandibular joint than conventional procedures. However, after IVRO there is always a risk of dislocating proximal bony fragments on the unrotated side. This risk may be caused by movement of proximal bony fragments inferiorly and/or medially before or at the time of fixation during surgery. We describe our experience with fixation of proximal bony fragments laterally to distal bony fragments using absorbable sutures to prevent dislocation of proximal bony fragments during opening and closing movements after fixation. Our method has been found to be satisfactory for preventing dislocation of proximal bony fragments after fixation in all patients who undergo IVRO.
