Solitary Neurofibroma of the Zygoma: Three-Dimensional Virtual Resection and Patient-Specific Polyetheretherketone Implant Reconstruction.

ABSTRACT: Intraosseous benign lesions rarely involve the zygoma, and intraosseous venous malformation is most commonly reported condition in the previous literature. A neurofibroma (NF) arising from the zygoma has not been reported before. Here, the authors present a 37-year-old female who developed solitary NF of the right zygoma. Surgical intervention is usually required for the treatment of a solitary NF. However, the complex three-dimensional (3D) anatomy of the zygoma increases the difficulty of the reconstruction for the operating surgeon. In this case, a preoperative digital surgical design was used to promote the efficiency of the surgery. A 3D printing surgical guide plate was used intraoperatively, and the defect was reconstructed by a patient-specific polyetheretherketone implant. Postoperative computed tomography imaging confirmed the accuracy of the reconstruction and that there was no recurrence of the tumor. The authors believe that the 3D print guide plate-assisted accurate resection combined with polyetheretherketone implant reconstruction is an ideal methodology for benign lesions of the zygoma.
