Soft-tissue changes related to the surgical management of mandibular prognathism.

A series of fifty patients treated surgically for mandibular prognathism has been analyzed statistically to study relative soft- and hard-tissue changes. Changes in the soft tissue of the chin and in the lower lip position relative to the underlying mandibular structures are well related in a nearly 1:1 ratio. Upper lip modifications have been shown to be less well related to mandibular repositioning. The ratio of change of mandibular landmarks to soft-tissue points and their over-all positional change can be helpful in presurgical treatment planning of patients with mandibular prognathism.

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.

Cat scratch disease: report of case and discussion.

A case of cat scratch disease with a submental mass as the initial symptom has been presented. The disease should be considered in the evaluation of swellings and masses of the cervicofacial region. However, because of the benign course of cat scratch disease, other more serious disease processes must be ruled out before establishing the diagnosis of cat scratch disease.
