Comparison of five methods of fat grafting

Recently autologous fat tissue transfer has gained much popularity. On the other hand, applying the transferring methods with a higher survival rate is still controversial. The aim of this study is to compare dermis-fat graft and dermal-fascia-fat graft. This animal study was conducted in 2008-2009. 12 dogs underwent fat graft transfer in forms of free fat, dermis-fat and dermal-fascia-fat. Two months post operation the grafts were removed and analyzed microscopically and macroscopically. The most significant weight loss was observed in circular free fat while, dermal-fascia-fat graft had the least. According to microscopical analysis the most considerable angiogenesis was improved in dermal-fascia-fat graft. Dermis-fat graft had a higher survival rate than free fat graft. Considering the higher angiogenesis and collagen synthesis used in the dermal-fascia-fat group, it seems that fat graft has more maintenance in the presence of fascia. To determine the influences of fascia further studies are recommended.
