Comparison of Customized and Prefabricated Silicone Implants in Asian Rhinoplasty Using 3D Technology

In Asian rhinoplasty, silicone implants are widely used for dorsal augmentation, but prefabricated implants often fail to reflect individual anatomy and asymmetry, leading to implant malposition or contour irregularity. This study evaluated whether a 3D-printed customized implant provides more precise dorsal correction than conventional prefabricated implants. We compared outcomes of silicone augmentation rhinoplasty for mild dorsal deviation or hump. Photographs were analyzed for dorsal deviation, hump angle, and dorsal irregularity. Customized implants achieved greater improvement in dorsal deviation and hump angle than prefabricated implants. Overall, 3D-printed customized implants provided more precise correction of mild dorsal deformities, suggesting improved anatomical conformity and dorsal contour stability.
