The use of 3-d models in the reconstruction of recurrent myxoma of the maxilla

Abstract

Objectives: To document the effective treatment of a recurrent myxoma involving the maxillary and zygomatic bone using a 3-dimensional (3-D) acrylic medical model to aid in reconstructing the surgical defect. Methods: Computed tomography, 3-D acrylic medical model, titanium mesh, calvarial bone graft, hydroxyapatite cement were used. Results: A young woman who had previously undergone a resection of a myxoid tumor in the right maxilla presented with a recurrence involving the zygomaticomaxillary suture. Due to the imposed large bony defect, a 3-D acrylic model was fabricated preoperatively to provide a template for reconstruction. Calvarial bone graft was harvested and sculpted with surrounding titanium mesh. Using the acrylic model enhanced the 3-D understanding of the reconstructive and aesthetic considerations. Conclusion: Myxoma is a rare benign odontogenic tumor that may pose a challenge in total surgical extirpation as well as reconstruction. Often, myxoma can be recurrent and limit the possible reconstructive methods due to the extent of disease. Reconstructing the surgical defect can be aided with the use of 3-D models created from reformatted computed tomography.
