Hollow Tuberosity

The maxillary tuberosity is one of the most likely areas to be affected by ischemia and infartion, probably because its blood supply is like that of an end-artery region.  Often the surgeon finds the entire tuberosity to be hollow, as was the case here.  Careful observation of the photo on the left will show a semicircle of radiolucency with the posterior wall of the tuberosity acting as the diameter or straight line of the semicircle, i.e. the circle faces toward the left.

Patient with trigeminal neuralgia, CN V2.

Regional Osteoporosis

This left mandibular third molar extraction site (tooth extracted 32 years previously) shows a poorly demarcated, subtle loss of trabeculae with the anterior margin showing a slight scalloping with a very thin and irregular sclerotic rim.  The entire area was filled with mushy, oily marrow.

Patient without pain.
