Surgical management of severe osteoradionecrosis of the mandibular bone by using double free flap reconstruction

Radiation therapy (RT) plays an essential role in the management of head and neck malignancies. RT is commonly used as an adjuvant to surgical intervention in cases of large tumors or metastasis, but also as a primary treatment modality (Deshpande et al., 2015; Rice et al., 2015). If primary or adjuvant RT is essential, osteoradionecrosis (ORN) of the jaws represents one of the most severe complications, with an incidence of 5–15%, mainly in the first few years after the end of treatment (Epstein et al., 1987; Reuther et al., 2003; Rice et al., 2015).
