title: Three-dimensional reconstruction after removal of zygomatic intraosseous hemangioma.
abstract: BACKGROUND
  Intraosseous hemangioma, especially in the zygomatic area, is a very rare pathologic condition among the osseous tumors of the head and neck area. Clinical presentation includes a painless mass with progressive growth and hard consistence. Diagnosis is performed by means of computed tomography (CT). Treatment includes radical en bloc surgical excision with healthy bone margins in order to avoid blood loss. Previous embolization is not necessary. Bony defect reconstruction must be performed to avoid secondary deformities.
  
  
  METHODS
  We present a case report of a 30-year-old female presenting a progressive painless swelling in the malar and zygomatic regions. CT scan demonstrated a right zygomatic lesion that extended into the orbital floor and lateral orbital wall, affecting also the zygomatic arch. The biopsy revealed an intraosseous hemangioma. Treatment was performed including an en bloc resection with healthy bony margins and primary reconstruction with calvarian bone graft in association with galea-pericranium flap.
