As a variant to the procedures of either injection of the capsule or removal of the discus articularis for recurrent dislocation of the jaw, I have come to prefer the following procedure as more positive than the first and simpler and more positive than the second.
A vertical 1-inch (2.5 cm.) incision is made about 1 inch anterior to the external meatus of the ear as shown in figure 1. The skin here tends to form vertical folds. If the closure is skilfully done the scar is hardly discernible. This line will correspond to the anterior border of the condyloid process of the mandible with its upper limit over the tubercle of the zygomatic process of the temporal bone. A speculum retractor (a in fig. 2 A and B) is pushed into the wound along and touching the anterior border of the neck of the mandible until it is stopped
