Hyperbaric oxygen therapy in the management of radiation-induced injury in the head and neck region: a review of the literature.

Purpose: Radiotherapy is generally used in the treatment of malignant tumors in the head and neck region. It causes a hypoxic, hypocellular, and hypovascular environment that leads to injury to surrounding normal tissue, both acute and chronic, ranging from xerostomia to osteoradionecrosis. These side effects are debilitating and greatly influence quality of life in these patients.

Continuous versus discontinuous distraction: evaluation of bone regenerate following various rhythms of distraction.

Purpose: To investigate continuous distraction osteogenesis (DO) of the nasal bones in a rabbit model, and to compare data from this continuous DO study with data from a previously conducted discontinuous DO study. In addition, radiographic and ultrasonographic bone-fill scores were determined to investigate whether these scores provided reliable predictive value for the amount of new bone formation in the distraction area.

Materials And Methods: Skeletally mature female New Zealand White rabbits were subjected to distraction of the nasal bones.
