ABSTRACT:
Introduction: High-flow oral and maxillofacial arteriovenous malformations (AVMs) are rare vascular anomalies characterized by direct communications between the arterial and venous systems, bypassing the capillary bed. AVMs can result in severe functional impairments, significant facial deformities, and a higher risk for life-threatening bleeding. Accurate diagnosis involves a thorough physical examination and imaging studies. Various sclerosing agents and embolization, combined with surgical treatment, are still the most standard approach to treating these lesions. However, the treatment of these disorders remains challenging due to high recurrence rates.
Objectives: The main objective of this work is to provide a comprehensive understanding of AVMs in the facial region, with a specific emphasis on underlining the imaging findings associated with this condition. Additionally, we aim to examine their clinical presentation, diagnosis, and management.
Materials and Methods: An imaging series of clinical cases involving oral and maxillofacial AVMs will be presented. In addition, a literature review will be conducted.
Results: Oral and maxillofacial AVMs are uncommon and heterogeneous vascular anomalies. Normally AVMs are present at birth but manifest mainly in childhood or adolescence. They have a gradual onset and progression. Diagnosis typically involves the use of various imaging modalities, such as plain radiography, computed tomography (CT) scans, magnetic resonance imaging (MRI), and angiography. A pictorial review of these imaging studies provides valuable insights for treatment planning and management. Treatment options often include a multidisciplinary approach, combining sclerotherapy, embolization, and surgical intervention.
Conclusions: AVMs in the facial region are complex entities that require careful diagnosis and management. A clear understanding of their clinical presentation, diagnosis, and management options is crucial for optimal patient outcomes.
