Jaw area messed up from cyst removal. What should I do? (photos)

I had a small cyst close to my neck or jaw area and the dermatologist took it out but now the skin is really thin and dents in and I can feel the bone and some lymph nodes and other things now. Its hollow its smaller on one side of my face. My face isn't full there any more. Is there any way to make it better?
