Background: Burn scars can hinder daily activities and
have an adverse effect on one's quality of life by causing
aesthetic and functional issues. Injecting adipose tissue that
has been acquired by liposuction into the dermis and/or
subcutis of the targeted body location is known as lipofilling.
It has been acknowledged as a promising procedure for the
treatment of scars as well as the correction of volume shortage
and skin renewal.
Objective: The objective of this study was to evaluate the
effect of Nano fat injection on post-burn scar patients in Suez
Canal University Hospital using the Patient and Observer Scar
Assessment Scale (POSAS).
Patients and Methods: A total of 26 individuals with postburn
scars at Suez Canal University Hospital Plastic Surgery
Clinic participated in this randomized controlled clinical trial.
Patients underwent a clinical examination that included determining
the location, size, shape, and time of the scar, as
well as their complaints of disfigurement, itching, burning,
discomfort, or contracture. Every patient had liposuction,
either from the thigh or the belly. After the fat was processed,
Nano fat was reinjected into the scar.
Results: Mean age of the patients was 29.65±3.94 years
with 84.6% females. Scaled burn with the commonest type
by 61.5%. The scars were distributed between the Upper
trunk (11.5%), lower trunk (69.2%), and head and neck
(19.2%). The main harvest site was the lower abdomen
(69.2%) followed by the inner thigh (30.8%). The mean
amount of the fat injected was 46.54±18.34 ranging from 15
to 80cc. Comparing the pre and post-operative observer
scores, showed that the improvement of the score in all items
(vascularity, pigmentation, thickness, relief, and surface area)
is statistically significant.
Conclusion: Our study's findings revealed a considerable
improvement in the various scar parameters following Nano
fat injection, making it an effective treatment option for
treating post-burn scars and enhancing patients' quality of
life.
