Application of Virtual Reconstruction 3D-Printed External Fixation Helmet in Early Functional Treatment of Facial Fracture.

Facial fracture repair is time-dependent. Early reduction and fixation after trauma help with later repair. Abnormal healing caused by delayed repair increases not only the difficulty of reconstruction, but also the risk of aesthetic or functional defects. Digital technology was used to model local trauma in three dimensions. The fracture fragments were reset, and the facial shape was reconstructed on the reset model. After resampling, 3D printing was used to construct a personalised external fixation helmet. Combined with the posterior nasal passage lift reduction technique, early reduction of the mid-face fractures was performed. Through the early application of a 3D-printed personalised external fixation helmet to a patient with a comprehensive fracture, the helmet manufacturing process and application methods were introduced, and the effect of this application was investigated. In the treatment of facial fractures, the early application of a 3D-printed personalised external fixation helmet is conducive to fracture reduction and fixation and reduces the difficulty of later reconstruction.
