What happens when..... the fibular free flap fails due to lack of blood flow thru the tissue, a pectoral flap is then done (leaving the bone in place), then a fistula causes an infection damaging that bone and the reconstructive surgeon wants to do another free flap after radiation.

My questions are - does anyone know...

Where is the next most likely donor source for the free flap?

What happens with the pectoral muscle that was already cut to make a flap? This muscle is pulled up thru the left side of his neck.

What are that chances that a 2nd free flap would fail, especially since this next surgery will be post radiation?

If anyone knows or has any experience in multipe reconstructive proceedures, it would be great to get some input. We won't see the surgeon until 2 months post rads, which will be mid November and I am hoping to get a handle on what might come next.
