Microvascular bone grafting: A new long-term solution for intraosseous arteriovenous malformations of the mandible in children


Bagherzadegan, N; Hohlweg-Majert, B; Mücke, T; Haerle, S; Deppe, H; Wolff, K D; Hölzle, F (2011). Microvascular bone grafting: A new long-term solution for intraosseous arteriovenous malformations of the mandible in children. Journal of Cranio-Maxillofacial Surgery, 39(6):431-434.

Abstract

BACKGROUND: Intraosseous arteriovenous malformations (AVMs) in the maxillofacial area are rarely reported in the current literature. These malformations have been associated with severe hemorrhage resulting in significant morbidity and mortality. The recommended gold standard treatment of AVMs is an endovascular embolization, combined with surgery. Especially in children, disease management remains a challenge for the surgeon due to the process of bone growth. AIM: In this report, we describe our experience with a microvascular bone graft as another possible surgical technique for the treatment of intraosseous AVMs in children. PATIENT AND METHODS: A 15-year-old boy was admitted to our department with a life-threatening hemorrhage due to an AVM of the left mandible. The attempt of an ordinary tooth extraction had lead to the emergency. Several embolizations and surgical interventions were required. Finally, a bony reconstruction with a microvascular bone graft from the right iliac crest was performed in order to achieve a normal form and function of the mandible. Postoperative recovery of the patient was unremarkable, and no recurrence was reported. Dental rehabilitation and a good esthetic outcome were achieved by insertion of dental implants. RESULTS: The performed interventions resulted in a complete anatomic and clinical cure. CONCLUSION: We suggest microvascular bone grafts from the anterior iliac crest as a valuable alternative in the long-term treatment of intraosseous AVMs, especially for extensive defects and in children.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
