title: Frontorbital Fibrous Dysplasia Resection and Reconstruction With Custom Polyetherlatone Alloplast.
abstract: Fibrous dysplasia (FD) is a benign, pathological development of bone. Craniofacial bones are the most commonly involved and can potentially cause visual disturbance, proptosis, orbital dystopia, and facial deformity. This case involves a 13-year-old girl with significant proptosis (20 mm left, 17.5 mm right) and downward displacement of the left globe (1.5 mm) due to fibrous dysplasia. Reconstruction was performed with computed tomography-derived and 3D printed custom polyetheretherketone (PEEK) implantation. PEEK is a nonabsorbable, nonporous thermoplastic polymer notable for its ability to be modified intraoperatively and ideal imaging properties postoperatively. Never, to our knowledge, has PEEK been used for primary reconstruction of the frontal orbital region in fibrous dysplasia in a child. The lesion was successfully repaired with excellent aesthetic and no apparent damage to neurovascular or ocular structures.
