Endoscopic eyebrow lift, titanium screws

I had an eyebrow lift on my right side for reconstructive purposes from a car accident. This is my 3rd eyebrow lift trying to raise it. This time the doctor put titanium screws, an endotine & sutures to keep it in place. He said the endotine will absorb but small screws are permanent. I believe they are titanium. Everything I read says they are usually removed after surgery. Is it okay that mine aren’t? Could there be any side effects or I have any problems from them staying in? I’m concerned.
