Abstract:
UNLABELLEDOBJECTIVE To make the computer tomography data based rapid prototyping models of the temporal bone and discuss its prospect for clinical application.
METHODSThree-dimensional models of one normal temporal bone and five dry temporal bones were reconstructed using volume rendering software of Materialise Mimics 6. 3 based on horizontal slices of one normal temporal bone and five dry temporal bones scanned and reconstructed with spiral CT. This model was duplicated with Auro SLA stereolithographic rapid prototyping machine and operational practice was performed.
RESULTSThree-dimensional computer model of temporal bone were reconstructed and duplicated successfully with clear bony marks on its surface and clear display of interior delicate structures on different sections. It was proved by operational practice that this model could be used for simulation of clinical operation of temporal bone.
CONCLUSIONSRapid prototyping technique could duplicate real model of temporal bone which could be used for preoperational practice. It had broad prospect of application in lateral skull base surgery and had significance for designing operational approach and decreasing complications.
