Abstract
Provided herein is an IVRO surgical guide for positioning a cutting guide on a mandibular ramus such that the mandibular ramus is clamped between a hooked distal end and a slidable component having a curved claw. The cutting guide is placed at a predetermined distance from the posterior edge of the ramus at the mid-waistline of the mandibular ramus along a curvilinear shaft in contact with the lateral surface of the ramus. The cutting guide can accommodate a saw for performing the osteotomy.
Claims17
An intraoral vertical ramus osteotomy (IVRO) surgical guide for a saw comprising:
- a curvilinear shaft comprising a hooked distal end and a cutting guide, wherein the cutting guide is configured to accommodate a saw;
- and
- a slidable component slidably engaged with the curvilinear shaft proximal to the cutting guide, wherein the slidable component comprises a curved claw.
A method for performing intraoral vertical ramus osteotomy (IVRO) comprising:
- engaging a hooked distal end of an IVRO surgical guide around the mid-posterior mandibular ramus of a patient such that a curvilinear shaft of the IVRO surgical guide is in contact with a lateral surface of the mandibular ramus;
- sliding a slidable component of the IVRO surgical guide proximally along the curvilinear shaft until a curved claw of the slidable component contacts the mid-anterior mandibular ramus such that the mandibular ramus is clamped between the hooked distal end and the slidable component and the curvilinear shaft is positioned along a mid-waistline of the mandibular ramus when the IVRO surgical guide is in the clamped position;
- and
- wherein the IVRO surgical guide further comprises a cutting guide located on the curvilinear shaft at a predetermined distance from the hooked distal end.
