| Popis: | 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. |
