Embolization as the Primary Treatment for Mandibular Arteriovenous Malformations: An Analysis of 50 Literature Reports and of an Illustrative Case.

PURPOSE: The aim of the present report is to describe 50 cases in the literature of mandibular arteriovenous malformations (AVMs) in which embolization was the primary treatment and to discuss details such as age, gender, materials used, outcome of embolization, time of follow-up, and intra- or postprocedure complications. An illustrative case in which reossification was noticed after embolization also is presented. PATIENTS AND METHODS: The study was carried out in 2 steps. In the first, an electronic search without time restriction for embolization as the primary treatment for mandibular AVMs was performed on Medline through PubMed. In the second, the case of a patient with mandibular AVM and massive oral bleeding episodes is described after a long-term follow-up. RESULTS: Clinical stability with the cessation of oral bleeding episodes was detected in 25 cases and 2 cases were planned for another embolization session. Clinical stability and reossification were detected in 23 of the 50 cases included. Complications were reported in 50% of cases, but most were minor and transient. CONCLUSION: Currently, owing to more sophisticated imaging techniques, the diagnosis of mandibular AVMs is quicker and new, less invasive techniques that avoid surgical resection have proved effective. It should be emphasized that these techniques are not without complications and that long-term monitoring is extremely important.

Hemimandibulectomia como tratamiento de ameloblastoma multiquístico / Hemimandibulectomy as multicystic ameloblastoma treatment

Ameloblastoma es un tumor de origen odontogénica que presenta crecimiento lento como una de las características principales, localmente invasivo y raramente causa metástasis. Pueden alcanzar grandes dimensiones si no tratado precozmente, convirtiéndose en un desafío su exéresis y reconstrucción en fases más avanzadas. El actual artículo tiene como objetivo relatar un caso clínico de un ameloblastoma multiquístico que afecta toda la región de la mandíbula derecha, en la cual fue realizado hemimandibulectomia, seguido de una reconstrucción con placa de 2.4mm y prótesis de cóndilo mandibular confeccionada en resina acrílica termopolimerizada, cubierta por el colgajo del músculo esternocleidomastoideo

The ameloblastoma is a tumor of odontogenic origin that present as main characteristics slow growth, locally invasive and they rarely cause metastasis. They can reach great dimensions if relegated the precocious treatment, turning his it complete removal and reconstruction in more advanced phases. The present article has as objective tells the clinical case of an ameloblastoma multicístico involving every area right mandibular, in which hemimandibulectomy was accomplished, following by reconstruction with plate 2.4mm and prosthesis of mandibular condylar made in resin acrylic thermopolimerizate, associated to shred of the muscle externocleidomastoideo
