Management of Mandibular ORN: PENTO as Medical Treatment

Summary

Mandibular osteoradionecrosis, despite its low incidence, remains being the most problematic and irreversible complication after head and neck radiotherapy with no medical treatment to limit or reduce symptoms. Different clinical trials have shown a significant scientific evidence that the treatment with pentoxifylline + tocopherol achieves a certain effectiveness in the treatment of the tissue fibrosis. This study proposes to use this drugs to determine if there is healing of mandibular osteoradionecrosis and/or a symptomatic improvement as well.
