Unfortunately, I can comment on the downside of bone cement, as I just had my first surgery dedicated to removing it. Yes, it can come out and cause some serious problems.

Like you, I had titanium in my body that was rejected. (And put me in the double-digit surgery column, too.)

But the most problematic: the bone cement used to replace the titanium plate and cover a surgical hole in my skull.

Only in hindsight, it was determined that as my body healed, it pushed the cement out and into the area between my skull and scalp around my right ear.

I endured pain, swelling, decreased hearing and balance and unrelenting tinnitus. I also had that “heavy” feeling you spoke about.

Then a small but painless cut appeared. It wouldn’t heal, so my doc ordered imaging. Within a week, I had surgery to remove the infection and the paste. It will soon be my 7th round of antibiotics (ranging from topical to IV).

I still have unanswered questions, and will probably need more surgery.

The bright side is that the right imaging can determine if the paste has migrated.

I wish you the best and hope that you find a solution soon.
