Intraosseous Venous Malformation of the Zygomatic Bone: Virtual Surgical Planning and Reconstruction With Customized CAD-CAM Titanium Implant.

Zygomatic intraosseous vascular anomalies are uncommon. Most cases have been reported without a precise diagnosis. The prevalence is 3:1 women during the fourth decade of life. The study of these lesions includes clinical findings, radiological studies, such as computed tomography and magnetic resonance imaging scans, and a postoperative histological study of the specimen. Biopsy is not recommended because of the risk of bleeding. Complete surgical resection remains the gold standard elective treatment.The case of a patient with an intraosseous venous malformation of the zygomatic bone is presented, detailing the clinical, histological, and radiological characteristics and the surgical treatment with a primary reconstruction through Computer-Aided Design/Computer-Aided Manufacturing customized titanium implant guided by virtual surgical planning with a reduction of surgical time and morbidity in the donor area with optimal functional and aesthetic results.
