Increased or Decreased Density.—If there is increased density, there is air loss in air containing structures or there is bone formation of some sort. There may be a decrease in density due to local destruction or other types of demineralization.

Decalcification or Destruction of Cell Partitions.—The air cells in the mastoid portion of the temporal bone which extend to the petrous apex, around the eustachian tube, into the tip of the mastoid, into the squamous portion, and behind the lateral sinus, are normally easily seen. Some patients have very thick walled cells. Some have very thin walled cells. Obviously, if
