Hi Gma,
I am so sorry for what you are going through! My titanium mesh healed very nicely after my surgery. But the following year, I had a Baha Connect implanted, and the doctor had to cut away some of my mesh to make room for it. The area didn’t heal properly, and I had to have another surgery to repair it. It was a source of depression and great stress for many, many months. The result has left the area behind my ear very lumpy, and the skin is thinner and more sensitive. I did have a point of the mesh cut through the skin at one time, but that has since healed. I have to be careful when putting on or removing my sunglasses, and wearing them for too long can make the area red and sore.
I know you are going through a lot more than I did, but I understand how stressful and frustrating it can be, and I wish you the very best result!
