jamie, I had a right modified neck dissection after rad/chemo. It took about 3.5 hours, but I didn't have any muscle replacement. I didn't have a trach, but I only had one side done. I was discontinued on the first surgery due to the pathologist not able to confirm no cancer on the spot biopsies that were taken from various parts of my mouth and throat. They brought me out of it and sent me home. Had to reschedule again and a second time as the surgeon threw out his back the day of the second schedule. Finally had it done and it was no big deal. Again, I only had one side done and didn't have a trach or muscle tissue transplanted. Hope it all turns out OK.
