RESUMO
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.
