I think it means you are going to get a neck disection with a graft, either from skin elsewhere from your body or a piece of your pectoral muscle. See this section for more about surgery:
http://www.oralcancerfoundation.org/facts/neck_dissections.htm

The purpose of the flap is to "bulk up" the area where the resection (removal of the tumor and clean margins) is.

"Necrotic" usually means dead tissue.

It sounds ominous but many here have been through it and the recovery time is around 3 weeks, about the same as if you had a face lift.
