Osteoradionecrosis (ORN) of the skull is a rare but fatal complication of radiation therapy for the treatment of head and neck malignancies. The pathogenesis of ORN follows the "3Hs Theory" proposed by Marx (J Oral Maxillofac Surg 1983;41:283-288) in which radiation induces tissue injury by causing
Hyperbaric oxygen therapy is of significant benefit in the setting of an ischemic flap of the head and neck. Mechanistically, hyperbaric oxygen decreases local tissue edema and improves oxygen delivery to compromised tissues. Both capillary and fibroblast in-growth occur at a greater rate with
Over the past 2 decades, breast-conservation therapy with lumpectomy and whole-breast radiotherapy has become a standard option for the majority of women with newly diagnosed breast cancer. Long-term local control is achieved in approximately 85% of patients, and the therapy is generally well
Radiation therapy of the brain, neck, and spine can be associated with radiation-induced changes that are increasingly evident radiologically. These changes affect the central nervous system (focal necrosis, diffuse white matter injury, atrophy, mineralizing microangiopathy, telangiectasia, optic
The bone marrow basically consists of red blood-forming bone marrow and yellow fat. In the skeleton, there is an age-dependent distribution of these two parts. In the context of medical interventions or therapies, bone marrow changes can occur, whereby the normal bone marrow can basically be
Background: One of the most important complications of radiotherapy (RT) for head and neck cancer (HNC) is osteoradionecrosis (ORN) of the jaws, arising mainly from tooth extractions. Thus, the present study aimed to evaluate the efficacy
