Utilizing 3D-printed Jigsaw Puzzle Surgical Guide and Frozen Autograft for Pediatric Craniofacial Tumor Reconstruction.

ABSTRACT: Pediatric midfacial tumor reconstruction is challenging due to complex anatomy and the need to preserve growth potential. This study presented a novel approach using a 3D-printed surgical guide jigsaw puzzle model and recycled frozen autografts for precise, minimally invasive reconstruction. A 6-year-old boy with spindle cell sarcoma of the right zygomatic bone underwent neoadjuvant chemotherapy before surgery. Preoperative computed tomography imaging and computer-assisted planning determined the resection margin. A polylactide 3-dimensional-printed skull model facilitated preoperative simulation, whereas a stereolithography-fabricated, 5-piece surgical guide enabled precise osteotomy through minimal incisions. The tumor-bearing bone was treated with liquid nitrogen cryotherapy and reimpla
