What are the options for restoration of lost sideburns after facelift? I am female, and in the UK.

A year ago I had a botched facelift resulting in the loss of my sideburns/temporal tuft. The incisions were in my temporal hairline and it seems that almost all the hair below the incision was permanently removed when the skin was excised. I also have a wide white scar here, where the incision was closed with staples. Will I be able to have a hair transplant procedure, even though the skin there is presumably now non-hair-bearing. If so, how successful is it likely to be, and what are the risks?
