Management of Intraosseous Vascular Malformations of the Jaws in Children and Adolescents: Report of 6 Cases and Literature Review

Background: Intraosseous vascular malformations represent a rare clinical entity of the facial skeleton. The purpose of the current study was to present our experience in a Greek paediatric population and propose guidelines for the treatment of these jaws anomalies in children and adolescents.

Methods: A retrospective study (from 2009 to 2014) was performed to investigate the features and management of the intraosseous vascular anomalies in a Greek paediatric population.

Results: Six patients aged between 6 and 14 years were treated for intraosseous vascular malformations (4 venous and 2 arteriovenous) of the jaws. Five lesions were located in the mandible and one in the maxilla. In four lesions with pronounced vascularity superselective angiography, followed by embolization was performed. Individualized surgical treatment, depending on the size and vascularity of the lesions was applied in 4 patients.

Conclusions: The intraosseous vascular malformations of the jaws may escape diagnosis in paediatric patients. A multidisciplinary approach is important for their safe and efficient treatment. Embolization is recommended for extended high-flow lesions, either preoperatively or as a first-line treatment, when surgery is not feasible without significant morbidity.
