Fat Grafting to the Forehead/Glabella/Radix Complex and Pyriform Aperture: Aesthetic and Anti-Aging Implications.

BACKGROUND

Optimal aesthetic outcomes from rhinoplasty are heavily influenced by structures adjacent to the nose. Although the importance of the chin has been emphasized since the inception of rhinoplasty, little attention has been given to the forehead. The forehead/glabella/radix complex represents a vital triad in rhinoplasty, from which the nasofrontal angle is derived. In the present study, the authors sought to determine whether fat grafting to the forehead/glabella/radix complex and pyriform aperture can favorably impact the nasofrontal and nasolabial angles, respectively.

METHODS

The authors reviewed pre- and postoperative images (obtained by an independent professional photographer) of patients who underwent autologous fat grafting to the forehead/glabella/radix region and the pyriform aperture, with or without concurrent rhinoplasty. Nasofrontal and nasolabial angles were measured on lateral images. Mean pre- and postoperative values were calculated and compared. A Wilcoxon rank-sum test was used for statistical analysis.

RESULTS

Twenty-six patients underwent fat grafting alone (FG group; mean follow-up, 3.3 years), and 19 had fat grafting plus rhinoplasty (FG + R group; mean follow-up, 5.2 years). The mean nasofrontal angle in the FG group decreased by 2.0° (P = 0.005), and the mean nasolabial angle increased by 2.3° (P = 0.006). The mean nasofrontal angle in the FG + R group decreased by 2.0° (P = 0.011), and the mean nasolabial angle increased by 6.0° (P = 0.026).

CONCLUSIONS

Autologous fat grafting to the forehead/glabella/radix complex and pyriform aperture is a reliable method to favorably influence the nasofrontal and nasolabial angles, respectively. Such treatment optimizes the interplay between the nose and the adjacent facial features, enhancing overall aesthetics.
