A RAPID PROTOTYPING BIOMODEL FOR FACIAL RECONSTRUCTIONS
Author(s):
Welington Martins Vieira, Flvio Serafini
Abstract:

The complexity of treating injuries to the facial skeleton that require reconstruction can be addressed effectively by rapid prototyping. This approach facilitates diagnosis, evaluations of existing defects, and strategic planning of the surgical event, potentially involving the customization of the alloplastic implants to be used. OBJECTIVE: To report a rapid prototyping biomodel used in two cases of facial reconstruction. CASE REPORT: We followed two cases of facial reconstructions guided by biomodels obtained by rapid prototyping. CASE 1: A patient diagnosed with mandibular condyle osteochondroma. A rapid facial prototyping biomodel was used to customize the condylar prosthesis prior to surgery. CASE 2: A patient with orbitozygomatic fracture sequelae, complaining of diplopia and midface asymmetry. The biomodel was constructed for the comparison of contralateral orbital and zygomatic measurements, and for osteotomy planning prior to orbitozygomatic block repositioning. CONCLUSION: The use of rapid prototyping biomodels in the treatment of these two reported cases provided superior diagnostic evaluations and improved intervention planning, with consequent reductions in surgical time, especially in case 1, where prosthesis customization was possible.
