title: Orthodontic management of the short face patient.
abstract: A short lower face may accompany various types of malocclusions depending on the structural etiology. Because most cephalometric analyses focus on the anteroposterior plane of space, they are often insufficient in diagnosing a significant vertical dysplasia. This article describes a cephalometric analysis that examines not only the vertical proportions of the face, but the various anatomical features that contribute to the dysplasia. Diagnosis is further enhanced by evaluating the facial profile with the mandible postured at various amounts of opening, suggesting the degree of vertical discrepancy. Traditional orthodontic therapy corrects the associated malocclusion but is usually ineffective in changing inherent facial proportions. However, several orthopedic methods have shown the ability to increase lower facial height when used in combination with nonextraction orthodontic mechanotherapy. Adults with short faces require a combination of orthodontics and orthognathic surgery. The Class II malocclusion can usually be managed by surgically advancing the mandible with the curve of Spee maintained. In cases of vertical maxillary deficiency, the LeFort I osteotomy with inferior repositioning provides the spatial correction that is needed. Two cases are presented to illustrate the cephalometric and facial analyses used in diagnosis, as well as the common surgical procedures to manage the short face patient.
