Mastoid bone on the right side is larger than my left. Is this normal or should I be worried?

Mastoid bone on the right side is larger than my left. Is this normal or should I be worried?

As you can imagine, the amount of air and fluid, entering these air sacs may vary, based on your medical condition. It is therefore, not surprising that one side of Mastoid may be different than the other. ...Read more

I was wondering does the mastoid bone grow back after mastoidectomy?

I was wondering does the mastoid bone grow back after mastoidectomy?

Mastoid regrowth: By definition, mastoidectomy is the REMOVAL of much or all of the mastoid bone and the mastoid air cells. The mastoid bone is the insertion of the sternocleidomastoid muscle, seen when turning the head from side to side as the linear muscle mass that defines the lines of the front of the neck. After removal of the mastoid bone, it will not "grow" back in its original form. It will remain absent. ...Read more

Hope this helps! ...Read more

What causes a lymph-node on your mastoid bone to stay enlarged for years?

Unlikely: Lymphatic system absorbs/carries things too big to go into arteries/veins like bacteria eaten by white cells and digested food. Lymph nodes "taste" lymph for bacteria/viruses/cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well. Persistence mandates evaluation. ...Read more
