A method and instrument for positioning a proximal segment of a buccal cortex to seat a condyle in the fossa during TMJ corrective procedures includes osteotomizing a mandible, thereby forming a proximal segment and a distal segment, drilling a burr hole in the proximal segment adjacent the osteotomy and inserting, into the hole, the tip of a positioning instrument having a handle, an elongated shaft and a stepped down tip angled approximately 45.degree. relative to the axis of the handle and shaft. The instrument can be manipulated from the patient's mouth in a minimally invasive and secure fashion.

Osteotomy blade

An osteotomy blade saw is provided in left-offset and right-offset embodiments for performing sagittal ramus osteotomies. The blade saw has first and second straight arm portions forming an obtuse angle between them, the end of the second arm terminating in a neck portion which angles acutely away from the plane containing the arms and terminates in an end portion on which a cutting blade is mounted. The blade lies in a plane parallel to the plane containing the arms and is offset to the right and left depending on the embodiment. Supplying reciprocating linear motion to the first arm allows the saw to be used in cutting bone. The blade saw in its two preferred embodiments can be used to score and cut the underside of the right and left inferior borders of the mandible, respectively, through incisions inside the mouth.
