Abstract
Background
The author presented his experience using "fat grafting" (FG) and "hyaluronic acid" (HA) techniques in nasal remodeling.
Objectives
The paper aimed to evaluate the efficacy and safety of the use of FG and HA in nasal remodeling for aesthetic improvement.
Methods
A randomized controlled trial was conducted. 15 patients affected by soft defects of the dorsum, low and boxy nasal tip, and hidden columella, were treated with FG (study group—SG), comparing results with the control group (CG) (n = 17) treated with hyaluronic acid (HA). Post-operative follow-up took place at 1, 2, 4, weeks, 3, 6, 12 months, and then annually.
Results
73.7% of SG patients showed excellent cosmetic results after 1 year compared with only 29.7% of CG patients. At one-month, major part of people who underwent the treatments (FG and HA) referred to satisfaction with the resulting volume contours (p = 0.389). 88.3% of CG patients versus 53.8% of SG described the HA and FG injection, respectively, as a very comfortable and non-invasive procedure. As expected, patient satisfaction with the appearance of nasal contouring was higher in the FG group at 1 year.
Conclusions
FG and HA were safe and effective in this series of cases performed.
