Postoperative stabilization and intrusion of midface osteotomies with high-pull headgear.

The two cases presented here illustrate advantageous uses of orthopedic-type craniomandibular headgear. Both cases demonstrate the use of headgear for postoperative cephalad movement of the maxilla. In Case 1 the use of headgear accomplished 6 mm. of anterior maxillary cephalad movement and 3.5 mm. of posterior maxillary cephalad movement. In Case 2 the use of postoperative headgear accomplished 8 mm. of anterior maxillary cephaled movement and 6.25 mm. of posterior maxillary cephalad movement. Table I indicates the duration of intermaxillary immobilization and the ensuing time that the cranial traction appliance was used. Fig. 10 illustrates the profile changes for Cases 1 and 2.
