Intra-mandibular arteriovenous malformations (IM-AVM) are rare congenital lesions sadly known by the appearance of cataclysmic haemorrhages. It represents a therapeutic challenge which requires a multidisciplinary approach. This paper aims to evaluate the characteristics and management of IM-AVM through the illustration of six case reports, the largest serie in the literature to our knowledge. This retrospective study included all patients with IM-AVM treated in the hospital of Lyon and Saint-Etienne between 1982 and 2021, in France. The management of mandibular AVMs should be individualized and permanently adjusted according to their stage of development, which makes their management difficult. Furthermore, long-term follow-up is essential to detect and manage the subclinical progression of the lesion. Based on these results and a systematic review of the literature, an algorithm has been developed to guide the treatment strategy for this are pathology.
