Background: Atrophic scars are a cosmetically distressing
problem for the patients especially post-burn ones as the
patient seek both restoring volume contour and improving
the quality of burn scar. To date there are no gold standards
exist for the treatment of scar tissue. Autologous fat grafting
has been introduced as a promising treatment option for scar
tissue and its related symptoms. However, the scientific
evidence for its effectiveness remains unclear. The aim of this
study was to evaluate the effect of autologous microbat grafting
on improving the aesthetic outcomes of post-burn atrophic
scars.
Patients and Methods: This study was conducted on 20
patients with obvious post-burn atrophic scars at different
body areas. Patients' age ranged from 16 to 35 years. The
lower abdomen and inner thighs were the most commonly
chosen donor sites. Microfat was processed by centrifugation
to be injected directly under the scar tissue.
Results: Significant improvement was noticed in the
pliability of scar with some improvements in pain and itching.
No improvement was noticed regarding vascularity and pigmentation.
Regarding patient satisfaction with cosmetic
appearance, 8 cases were not satisfied and 12 cases were
satisfied. However, most of patients (16 cases) were satisfied
regarding restoration of volume contour.
Conclusion: Autologous microfat grafting has a minimal
effect on improving the aesthetic outcomes of post-burn
atrophic scars. On the other hand, it has a great effect on
restoring the volume contour of the scars.
