Application of Hydrogel in Reconstruction Surgery: Hydrogel/Fat Graft Complex Filler for Volume Reconstruction in Critical Sized Muscle Defects

Figure 6

Artificial created muscle defect with different treatment in 6 months’ healing period. Comparing defect treated with hydrogel/fat graft complex and simple fat graft transplantation, a more even and smooth fat pad can be observed at the 6-month time point. First trace of new fat pad development could be observed in 3-month time point (black arrow). There is a continuous development of fat pad throughout the observation period with the hydrogel/gat graft complex group. Tissue volume is fully restored by the fat pad after 6 months.
