Pilot study of applying digital visible models for endoscopic nasal surgery / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To study the benefits of applying digital visible models for endoscopic nasal surgery.METHODS CT data sets of 16 patients were segmented to create digital visible models by using AutoCAD(computer aided design),MOI (Moment of Inspiration) and SketchUp software package.Standard digital available data sets for clinical tasks such as surgical simulation and surgical planning.The digital visible models and the intra-and postoperative corresponding visions were compared. RESULTS The 3D structure model of nasal cavity, sinuses and their adjacent structures for endoscopic nasal surgery were successfully reconstructed.The models allowed the user to interact with the data and manipulate them(in the view of X-ray,looking around inside the model).The model can be observed during operation,provided accurate morphological data for surgery guidance plan.CONCLUSION The method creating digital visible models using AutoCAD,MOI and SketchUp software package is simple and feasible.The digital visible models are suitable for clinical use as well as for education of endoscopic nasal surgery.The benefit of this technology was confirmed by clinicians.
