Comparison of Profile Attractiveness after Compensatory Filler in Different Regions of the Face in Individuals with Chin Deficiency

Objective: The present study aimed to evaluate and compare the profile attractiveness after compensatory filler in different regions of the face of individuals with chin deficiency. Materials and Methods: The sample consisted of 24 patients with chin deficiency treated compensatorily with facial fillers. The patients were divided into 3 groups: Group C- Chin: 11 patients (1 man, 10 women), with a mean age of 31.27 years (s.d.=9.72), who received chin filler with iPRF. Group CN- Chin and Nose: 9 patients (2 men, 7 women), with a mean age of 32.33 years (s.d.=8.17), who, in addition to filler the chin with iPRF, also received rhinomodeling. Group CNL- Chin, Nose and Lips: 4 patients (4 women), with a mean age of 29.00 years (s.d.=4.24), who received, in addition to filler the chin with iPRF and rhinoplasty, filler of the lips with iPRF. The attractiveness of the profile before and after the filler was evaluated in profile photographs with scores from 1 to 10, with 1 being less attractive and 10 the most attractive. The evaluation was performed by 82 individuals, 45 specialists in Orthodontics or Orofacial Harmonization (27 female, 18 male, mean age 39.11 years, s.d.=9.06) and 37 laypeople (27 female, 10 male, mean age of 39.88 years, s.d.=15.97). The comparison between groups C, CN and CNL was performed by the one-way ANOVA and Tukey tests and for the comparison between specialists and laypeople, the independent t-test was used. Results: There was a statistically significant difference in the profile attractiveness among the different types of compensatory facial filler. After filler, the CNL group became the most attractive, followed by the CN group and lastly and the least attractive was the profile of the C group. The amount of improvement with the compensatory filler was greater in the CNL group, followed by the CN group and lesser in the C group. In the evaluation performed by laypeople, the improvement and attractiveness of the profile after filler were significantly greater than in the specialists’ assessment. Conclusion: The filler of the chin, nose and lips resulted in a greater attractiveness of the facial profile, followed by the filler of the chin and nose, and lastly, the filler of the chin only.
