[The application of CAD/CAM technology on the reconstruction of the thyroid cartilage]
Objective:
To explore the value of computer-aided design/computeraided manufacturing (CAD/CAM) technology for individual reconstruction of the thyroid cartilage defects.
Method:
Select the 20 New Zealand white rabbits (male or female). Randomly divided into two groups. Group A in the pre-operative CT scan of the throat, three-dimensional reconstruction of the thyroid cartilage imaging, surgical removal of either side of the thyroid cartilage, defect implanted in the use of CAD/CAM technology and mirror technology to produce personalized restorative materials; Group B surgical resection either side of the thyroid cartilage, defect implanted production of non-personalized probably according to the experimental animals unilateral thyroid cartilage repair materials. After surgery by gross observation, electronic laryngoscopy observed experimental animals throat.
Result:
General check and electronic laryngoscopy show: the use of CAD/CAM technology to prepare the individual repair materials throat plays better supporting role than the non personalized materials.
Conclusion:
CAD/CAM technology before surgery designed to provide a personalized solid model to improve the accuracy of the surgery, time saving surgery to reduce surgical complications.
