That's good news! I guess the time between radiation may matter, the dosage amount to the mandible, which have more cases of ORN than the upper jaw, and read the chances are small, maybe 1-3%, but it's horrific enough to be a concern. Not all doctors recommend HBOT these days, mine do, and is individually based. I'm treated in Manhattan, where they have three monthly SPOHNC support group meetings at different hospitals, and in LI, and Upstate also, which help, if ever interested.
