Abstract Fat injections aid in the healing of radiation-induced skin damage. We hypothesized that the direct application of fat grafts to the surfaces of radiation-induced ulcers is also effective. Here, we aimed to evaluate the effectiveness of a combination treatment comprising fat injections around ulcers and fat grafts on ulcer surfaces. The dorsal skin of inbred rats was irradiated at a single dose of 20 Gy before producing ulcers. After the inguinal fat was harvested using the Coleman technique, the rats were divided into four groups: Group 1, ulcer wounds were covered using dressing materials and staples only; Group 2, fat was injected around the ulcers using a cannula; Group 3, fat was grafted onto ulcer surfaces; and Group 4, a combination of fat injection around the ulcers and fat grafts onto ulcer surfaces was employed. The mean healing time (± standard deviation) of each group was as follows: Group 1, 16.0 ± 2.2 days; Group 2, 14.5 ± 2.0 days; Group 3, 15.2 ± 1.7 days; and Group 4, 13.4 ± 1.0 days. The healing time of Group 4 was significantly shorter than that of Group 1 (p = .0005) and Group 3 (p = .023). In both groups that received fat grafts, fat tissue was observed in the dermis on hematoxylin-eosin-stained slides at 4 and 8 weeks after the ulcers were created. In conclusion, the combination treatment of fat grafted onto ulcer surfaces and injected around ulcers was effective in accelerating the epithelization of radiation-induced ulcers.
