Abstract
Patients who survive after receiving burns or large areas involved in trauma, have residual functional and aesthetic complications that represent significant health problems. In addition, such burns or trauma can create so¬cial, economic, and psychological problems. Despite medical attempts to treat the sequelae of burns, long-term outcomes and scars often show little improvement.
The first known report of fat graft was made in 1893 by German surgeon Neuber, after that many surgeons published papers in fat graft. Recently, fat graft becomes a popular procedure in medicine with many uses. Sydney R. Coleman who consider pioneer of fat graft in last two decade comprehensively presented the principles for structural fat grafting to achieve a long-lasting result, with applications in different anatomic regions, in his landmark text, Structural Fat Grafting.(20)
In addition to the traditional understanding that fat is a high-energy reservoir that is intimately involved in homeostasis, it becomes apparent that fat is also an organ with repair capabilities. When fat is transplanted to another part of the body, these reparative properties appear pronounced.(22)
This work was undertaken to assess the effect of fat injection in remodeling of post-burn and post-traumatic scars.
The present study included 20 patients suffering from scars. Eleven patient were suffered from post-burn scars while nine patients were suffered from post-traumatic scars. The age range was (7-54) years old and the mean age is 24.6 years old.
The number of treatment by injection range (1-3) and mean is 1.3.Total amount of injected fat rang (3-54) and mean is 17.1
Pre-operative and post-operative assessment by Vancouver scar scale has been done with improvement range (1-4) and mean is 2.1.The improvement in scars observed was best in pliability, moderate in vascularity, pigmentation and absent in height.
Early complication such as infection and embolism are not seen in any of our patients. Also, bruising and skin tethering was not recorded in any case. Asymmetry was seen in two cases; however this is corrected in the following sessions.
First parameter assessed was the vascularity. All of our cases (20 case, 100% of cases) was normal vascularity (grade 0 in Vancouver scar scale). This is because we excluded immature scar from our study.
Second parameter assessed was the pigmentation. Eleven patients (55%) had a hyper pigmented scar (grade 2 in Vancouver scar scale); only in two cases hyper pigmentation disappeared. However in the other cases hyper pigmentation obviously decreased. Three cases (15%) had a hypo pigmented scar (grade 1 in Vancouver scar scale), in all three cases hypo pigmentation was not improved. In the rest of patients (6 patients, 30%) scars was normal in pigmentation.
