INTRODUCTION: The treatment of epistaxis sometime requires an embolization. This may result in ischemic palate necrosis, oronasal communication and dental losses. The repair of these lesions is complex.
OBSERVATION: A 53-year-old patient, suffering from high blood pressure and hypercholesterolemia, benefited from bilateral embolization of the sphenopalatine arteries in order to treat a persistent epistaxis. He developed a middle cerebral artery stroke in the aftermath. During the treatment of the neurological sequelae, a necrosis of the 2/3 of the posterior aspect of the hard palate was discovered. The angio-MRI showed an obstruction of both sphenopalatine arteries and of their vascular supplies resulting in a bilateral involvement of the alveolar bone. The diagnosis of iatrogenic palate necrosis was made. Tissue repair was successfully achieved by two loco-regional flaps. The dental rehabilitation was made by mean of a removable prosthesis.
DISCUSSION: Palatine necrosis following embolization of the sphenopalatine arteries is uncommon. Ischemia resulted in a loss of substance in form of a punch, similar to noma's lesions. It could also be a consequence of the vascular background. The management of these lesions is complex and calls for forensic reflection about the iatrogenic origin.
