“…There was no relationship between the time of onset and the future clinical course of bone necrosis. The revascularization of bone within the radiation field, as speculated by Hoffmeister et al 13 on the basis of an experimental animal model, either does not occur or is not clinically significant at the higher dosage levels.…”

Osteoradionecrosis: Predisposing factors and outcomes of therapy

Eighty-three episodes of osteoradionecrosis are reported. Of those episodes affecting the mandible (78), 23 (29.5%) required radical resection. The most common precipitating factors were postradiation extractions (22/83), periodontal disease (19/83), and preradiation extractions (17/83). Those episodes initially located within the zone of attached mucosa fared well with conservative measures while those initially located beyond the zone of attached mucosa fared poorly. In bone necroses where the external radiation dose to the affected bone exceeded 7,000 rad, the mandibular resection rate was high (44%). The most effective way of resolving advanced bone necroses was achieved with a course of hyperbaric oxygen therapy combined with a surgical sequestrectomy.

“…The pattern of blood supply to the mandible has been implicated as a primary reason for this finding 37,79 . Other more simple explanations claim that the mandible is included in the radiation field more often than the maxilla 29,79,82 .…”

“…Es besteht also kein Grund anzunehmen, dass in der Pulpa keine vergleichbaren Veränderungen stattfinden sollten. Der posttherapeutisch im Strahlenfeld reduzierte Blutfluss würde auch eine Erklärung für die klinisch sinkende Sensibilität, insbesondere mandibulär distal des Strahlenfelds liefern [22]. Obwohl histologisch keine Veränderungen der Nerven feststellbar sind, fehlt durch die verschlechterte Versorgungssituation die nötige Energie zur Weiterleitung nervaler Impulse [31].…”
