Fig. 2 A, Ivy loop wiring of right mandibular bicuspids/cuspids in preparation for right mandibular condyle subluxation. B, Second wire loop placed around contralateral maxillary bicuspids/cuspids. C, After right condylar subluxation the wires are twisted together to maintain mandibular fixation. D, Lateral view demonstrates subluxation of right mandibular condyle onto articular eminence.

Fig. 3 A, 3/32 inch Steinmann pins drilled into the right side of the mandible (anterior to the mental foramen) and into the contralateral maxilla in preparation for right mandibular condyle subluxation. B, Connecting wires attached to pins. C, After right condylar subluxation the wires are twisted together to maintain fixation. D, Lateral view.

Fig. 4 Exposure of distal right ICA obtained after mandibular subluxation, division of posterior belly of digastric muscle and styloid muscles, and ligation/division of occipital artery. The styloid process can be excised for additional exposure.
