A Novel Composite Skin Graft Technique with Fat Derivatives

摘要

Skin grafting,although a relatively classic and well-known technique,still has multiple disadvantages such as secondary contracture of the skin graft,sunken depression,poor elasticity,and color mismatch.Adding adipose tissues significantly improved the graft appearance compared to traditional skin grafting methods.Herein,we report two cases of modified skin graft procedures,both showing positive outcomes.In case 1,a mechanically processed fat-derived product was injected into the lower half of the skin graft area.In case 2,left upper eyelid blepharoplasty was performed,and the orbital fat strip was transferred and placed under the recipient area on the right side.Hair growth was observed only in case 1,whereas the extent of sunken depression was significantly reduced in both cases.Compared to traditional skin grafting methods,adding fat components to the skin graft recipient area improved the appearance and blood supply,together with enhancing the regenerative rate.
