[The application of three-dimensional visualization in the endoscopic thyroidectomy].

To explore the application value of three dimensional（3D） visualization in the endoscopic thyroidectomy. Fifty patients with thyroid papillary carcinoma confirmed by preoperative fine needle aspiration（FNA） were randomly divided into the combined group （20 cases） and the simple operation group （30 cases）. Endoscopic thyroid surgery combined with three-dimensional visualization model was used in the combined group. Simple operation group was treated with simple endoscopic thyroid surgery. The communication time and communication satisfaction, intraoperative blood loss, operation time and postoperative complications between the two groups were compared. The communication time with patients in the combined group and the simple operation group before operation was （23.05±6.83） min and （28.83±8.57） min. The communication time in the combined group was shorter, and the patients' satisfaction with disease awareness was higher after communication. There was a statistically significant difference between the two groups （<0.05）. The operation time of combined group and simple operation group was （104.30±13.06） min and （130.46±17.01） min respectively, and the operation time of combined group was shorter （<0.05）. The intraoperative bleeding volume of combined group and simple operation group was （12.80±6.10） mL and （17.60±5.19） mL , and the combined group had less intraoperative bleeding volume （<0.05）. There was no significant difference in postoperative complications between the two groups （>0.05）. 3D visualization technology will benefit to improve the efficiency of doctor-patient communication, enhance the safety of the endoscopic thyroidectomy, and then accelerate the postoperative rehabilitation of patients, which worthy of clinical promotion and practice.
