Osteoradionecrosis (ORN) is one of the most feared complications after head and neck radiotherapy. Among head and neck sites, the mandible is the most commonly involved bone. Heavy ion radiotherapy delivers high-dose distribution focused to the target while simultaneously sparing of the adjacent organs but there are anyway some reported cases of ORN. Cases in literature reported well-known risk factors for its developing (e.g. tobacco and alcohol abuse, diabetes), but other are still debated (e.g. teeth extraction during radiotherapy). Prevention is mandatory but multimodal care may be required, tailoring all treatments on the patient needs. This study, after a brief revision of the literature, reports and a case of maxillo-mandibular ORN following carbon-ion (C-ion) radiotherapy and its treatment.

Abstract
Osteoradionecrosis (ORN) is one of the most feared complications after head and neck radiotherapy. Among head and neck sites, the mandible is the most commonly involved bone. Heavy ion radiotherapy delivers high-dose distribution focused to the target while simultaneously sparing of the adjacent organs but there are anyway some reported cases of ORN. Cases in literature reported well-known risk factors for its developing (e.g. tobacco and alcohol abuse, diabetes), but other are still debated (e.g. teeth extraction during radiotherapy). Prevention is mandatory but multimodal care may be required, tailoring all treatments on the patient needs. This study, after a brief revision of the literature, reports and a case of maxillo-mandibular ORN following carbon-ion (C-ion) radiotherapy and its treatment.File | Dimensione | Formato | |
