Yes ideally you don't leave this stuff up to the drs and nurses. You call immediately if things go on for too long - ideally when hospice didn't show someone should have been on the phone immediately to find out what is going on. Only family can advocate well for a loved one. That's all done now start making calls and kick them into high gear do not take a long wait date for the surgery - start making noise - someone clearly dropped the ball and that should be made known to everyone you are dealing with this way they will get him in as quickly as possible, 6 weeks is the normal wait period after surgery for healing but they could have prepped him and. Gotten him ready for his mandiblectomy at the ver least they should have have been monitoring him - hugs and make noise.
