Nasal deformities due to trauma are more challenging to correct with rhinoplasty than nasal deformities of nontraumatic causes. Nasal osteotomy is an essential procedure for bone deviations. Preoperative planning is vital in these cases, but it is challenging to comprehend 3-dimensional (3D) structures of the nasal bone on 2-dimensional facial photographs and computed tomography images. We used a 3D-printing technique to fabricate real-size facial bone models with similar physical properties and texture as the actual bone. Furthermore, we established a precise surgical plan using simulated osteotomy on the 3D-printed model. Fused deposition modeling-type desktop 3D printer with polylactic acid filaments was used. A surgical plan was established using simulated osteotomy in 11 cases, and the actual surgery was performed as planned in 10 cases (90.9%). The 3D-printed model and stimulated osteotomy were useful for precise planning of osteotomy to correct nasal deformities due to trauma.
与非创伤性原因导致的鼻畸形相比，创伤性鼻畸形通过鼻整形术矫正更具挑战性。鼻骨截骨术是矫正骨偏曲的关键手术。术前规划在这些病例中至关重要，但在二维面部照片和计算机断层扫描图像上理解鼻骨的三维（3D）结构具有挑战性。我们使用3D打印技术制作具有与实际骨骼相似物理特性和纹理的真人大小面部骨骼模型。此外，我们在3D打印模型上使用模拟截骨术制定精确的手术计划。使用了带有聚乳酸细丝的熔融沉积建模型桌面3D打印机。在11例病例中使用模拟截骨术制定手术计划，10例（90.9%）按计划进行了实际手术。3D打印模型和模拟截骨术有助于精确规划截骨术以矫正创伤性鼻畸形。
