3-D modeling capabilities for planning rhinologic surgical interventions from CT-datasets

Abstract

The essence of the development is to obtain data from imaging tools, as a rule, spiral computed tomography, which allows visualizing bone-cartilaginous and soft tissue structures of the nasal cavity with high spatial resolution and contrast, preparing a 3D model for prototyping using specialized programs -slicers dividing the reproduced object into sections, taking into account the hardware features of the prototyping device, the 3D printing stage for obtaining a mode and implementation of this model is given manipulation -training with the help of selected surgical instruments. After a virtual change in the spatial configuration of the nasal cavity and re-manufacturing of a real model, it is possible to conduct comparative tests of both full-scale models on an aerodynamic bench to determine and analyse indicators of nasal resistance -pressure drop and corresponding air flow.
