Aesthetic and Psychosocial Impacts of Hyaluronic Acid Fillers in Patients with Retrognathic Profiles.

Objective: This study evaluated the effectiveness of hyaluronic acid (HA) in redefining the lower third of the face in orthodontically treated individuals with well-defined skeletal bases, focusing on its influence on facial aesthetics, self-esteem, and quality of life.

Method: Twenty-four individuals aged 19-43 years with retruded chins participated in the study. Data collection included socioeconomic questionnaires and validated instruments such as the OHIP-14, Face-Q™, Rosenberg Self-Esteem Scale (RSES), and the Brazil-validated Orthognathic Quality-of-Life Questionnaire (B-OQLQ). Changes in perceived attractiveness were assessed through standardized pre- and post-treatment photographs. HA fillers, with rheological properties of high cohesiveness and elasticity, were applied to specific facial points based on the Medical Codes (MD Codes™) protocol. These points were strategically selected to project the chin, define the jawline, and improve the contours of the lower third of the face, using standardized techniques to achieve aesthetic harmony.

Results: A statistically significant improvement in satisfaction with the chin and jawline (p < 0.000755) was observed, accompanied by a substantial increase in perceived attractiveness after the treatment. A notable migration to lower B-OQLQ scores (< 10) indicated improvements in self-image and quality of life. Observers, including orthodontists, facial harmonizers, and laypeople, consistently rated post-treatment images as more aesthetically pleasing.

Conclusion: HA fillers demonstrated high efficacy in improving facial aesthetics, self-esteem, and quality of life in retrognathic patients post-orthodontic treatment. These findings support the use of HA as a minimally invasive alternative for facial enhancement.
