Anterior Cervical fusion & Posterior laminectomy

I posted another question re: cervical fusions weeks ago. I had an ACDF on C3-4-5 in November 2016.
The surgery site is in perfect condition. I now have to have another fusion on C6-7 and T1 due to compression on my spinal cord at C6. My latest MRI revealed moderate to severe central canal stenosis and moderate to severe bilateral foraminal narrowing at C3-4; severe central canal stenosis and severe bilateral foraminal narrowing at C4-5; severe central canal stenosis with compression of the cord (w/o definite abnormal cord signal and moderate bilateral foraminal narrowing at C6-7; moderate to severe central canal stenosis with severe left and moderate right foraminal narrowing at C7-T1.
I've gotten 3 different opinions from 3 neurosurgeons. #3 is recommending stand-alone cage between C5-6; anterior fusion for C6-7-and T1; then laminectomies )performed from posterior) at C3-4-5, and C6-7 and T1.
I'm concerned about having this amount of surgery all at one time. Has anyone had such extensive surgery involving anterior and posterior entry? Thank you.
