Abstract: Summary ORNJ is a most severely complication of radiation therapy for head and neck cancer. Up to now, the precise pathogenesis of ORNJ has not been fully clarified, the newest one is radiation-induced fibrosis. It is believed that the hard and soft tissue of radiation area formed lots of pathologic fibrosis tissue through a series of changes after irradiation; subsequently, the pathological fibrous tissue disintegration caused ORNJ. Myofibroblasts play an important role in the fibrosis of liver, lung, kidney and scleroderma, whether it also plays an equally important role in ORNJ has yet to be confirmed. This paper mainly demonstrated the simple pathogenesis of ORNJ, the characteristics of the myofibroblasts, relationship and distinction between myofibroblasts and fibroblasts, and myofibroblasts and ORNJ.

Key words: Osteoradionecrosis, Myofibroblasts, Fibroblasts, Radiation-induced fibro-atrophic process
