As long as we're on the subject, after radiation, ORN can be caused by the vasoconstricter effects of novocain (makes the novocain stay in the local tissues longer) For this reason we all should ask for local anesthetic that does not cause vasoconstriction. Carbocain I think is the name of one such local anesthetic. Perhaps Jerry the Dentist could elaborate.

Mark, 21 Year survivor, SCC right tonsil, 3 nodes positive, one with extra-capsular spread. I never asked what stage (would have scared me anyway) Right side tonsillectomy, radical neck dissection right side, maximum radiation to both sides, no chemo, no PEG, age 40 when diagnosed.
