OBJECTIVE: To determine the mean soft tissue facial profile for Persian adults as determined by the Holdaway analysis.
MATERIALS AND METHODS: Lateral cephalometric radiographs for 62 Persian adults with normal occlusion were used.
RESULTS: Persian adults have the same values of Holdaway soft tissue norms except for the skeletal profile convexity, H angle, basic upper lip thickness, and soft tissue chin thickness, which were increased in Persians in relation to Holdaway norms. When comparing men with women, the nose prominence (P < .001), basic upper lip thickness (P < .001), upper lip thickness (P < .001), inferior sulcus to H line (P < .001), and soft tissue chin thickness (P < .01) were significantly increased in Persian men compared with Persian women.
CONCLUSIONS: Persian adults differ from Holdaway's soft tissue norms in an increased skeletal profile convexity, H angle, basic upper lip thickness, and soft tissue chin thickness. These are recommended for use when formulating a treatment plan for this ethnic group.
