Hoping for a safe way to remove backed out screw from ACDF without har

In 2019 I had a ACDF at C4-C7 for severe spinal cord compression with no complication's. In January 2026 I first started out having neck pain and pain underneath my left shoulder. Long story, short. Now my neck is a little sore when moving it. I don’t have the pain I did have but now have weakness and  losing strength in my left hand. Recently I had a CT scan and it showed a new C7/T1 disk herniation that the doctor said is causing the left hand numbness. It also shows the C7 screw from the 2019 surgery has backed out completely and is in the pre-vertebrae soft tissues. It abuts the right side of the esophagus and indents the posterior trachea. Obviously it is not anchored to the interior cervical plate and Dr said it will move with retraction and be extremely difficult to find. If there is damage to the esophagus and trachea, we would have to abort the surgery and have a vascular surgeon become involved. I was told this is very serious and a life-threatening problem. 
Just wondering if anyone has had experience with this type of issue and what the outcome was.
