Does postoperative radiation within 24 hours of a skin graft with a keloid resection increase the risk of graft failure?  

The amount of radiation required to prevent keloid recurrence after excision is lower than what would be expected to compromise a skin graft. The studies cited are dealing with postoperative radiotherapy for cancer, where radiation doses are required to be higher than what is used for a keloid, and ...

I am not aware of any data looking at this question. However, extrapolating from several papers on the subject of the recommended timing for post-op RT after skin grafting for excision of NMSCs, I agree with Dr. Mendenhall that I suspect that post-op RT within 24 hours would likely result in higher ...

I don’t know, but I suspect yes.
