A member asked:

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

A doctor has provided 1 answer

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.
