Background
Facial skeletal asymmetries in Class III subjects seeking orthognathic surgery may complicate subsequent treatment.
Objective
The purpose of this study was to investigate facial asymmetry in orthognathic surgery patients with Class III malocclusion.
Methods
The Class III group consisted of 29 orthognathic surgery patients (14 female, 15 male; Mean age: 21.44 years) with Class III malocclusions. The Control group consisted of 32 subjects (16 female, 16 male; Mean age: 19.20 years) with excellent Class I occlusal relationships. Facial skeletal asymmetry, based on the skeletal midline, was measured on postero-anterior radiographs. In the Class III group, the chin point deviated to the ipsilateral side. The side-to-side and between group differences were compared.
Results
In the Class III group, the antegonial notch – skeletal midline distance was significantly larger (
Conclusions
Subjects with Class III malocclusion may have facial skeletal asymmetries, predominantly in the lower face. Frontal asymmetries should be considered during diagnosis and treatment planning.
