Assessment of the Effect of Simulated Rhinoplasty and Genioplasty on the Facial Profile Attractiveness of Patients with a Convex Face.

AIM

This study was performed to evaluate the effect of rhinoplasty and genioplasty on facial profile attractiveness assessed by orthodontists and laypersons.

MATERIALS AND METHODS

In this study, posttreatment cephalo-grams of 30 class II patients with convex profile and nasal hump who had undergone camouflage treatment were traced. These profile outlines were modified by computer software to simulate rhinoplasty and genioplasty. Then, all these outlines were converted into silhouettes. There were four groups: no modification, rhinoplasty (R), genioplasty (G), and rhinoplasty plus genioplasty (RG). Esthetic assessment of all patients was done by two panels: six orthodontists and six laypersons. Data were analyzed using Friedman's and Wilcoxon's test with a significance level of 0.05.

RESULTS

The highest mean esthetics scores belonged to RG (3.9 ± 0.6), followed by R (3.5 ± 0.5), G (2.4 ± 0.5), and the initial image of the patients (2.13 ± 0.5). There was a significant improvement following all surgeries as determined by all evaluators (p < 0.001), except for orthodontists who did not find genioplasty more esthetic than no modification (p = 0.139). The mean score of esthetics by orthodontists was more than laypersons in all groups (p > 0.05).

CONCLUSION

Both rhinoplasty and genioplasty improved the attractiveness of the patients' facial profiles. The greatest improvement in the facial profile attractiveness in convex faces was observed after simultaneous nasal hump elimination and chin argumentation procedures.

CLINICAL SIGNIFICANCE

Although both rhinoplasty and genioplasty could improve patients' profile, the best result is achieved when combination of them is used for treatment of convex facial profile patients.
