OBJECTIVE: To summarize the experiences of applying three-dimensional (3D) technique in scarless endoscopic thyroidectomy (SET) via anterior chest approach. METHODS: Medical records of patients who undenvent SET using 3D technique from December 2013 to May 2014 were retrospectively reviewed. A total of 32 patients who had a preoperative ultrasound-guided fine-needle aspiration cytology diagnosis of unilateral papillary thyroid carcinoma and underwent lobectomy associated with central lymph node dissection were included in this study. All patients were female with a mean age of (37 ± 10) years at diagnosis. In addition, 45 female patients who underwent traditional endoscopic thyroidectomy at the same period were randomly selected as control. RESULTS: All surgical procedures were successfully finished. The mean surgical time in 3D group was (91. 7 ± 11. 4) minutes, and mean hospitalization time was (3. 2 ± 0. 5) days. Contemporary hoarseness was observed in one patient, and no bleeding, infection, hypocalcemia and other postsurgical complications were observed. Compared to the traditional endoscopic surgery group, 3 D group had significantly shorter surgical time of lobectomy ((23. 2 ± 5. 1) minutes vs. (28. 0 ± 5. 0) minutes, t = 4. 156, P = 0. 000). Negative results were seen in the time taking of creating surgical space ((14. 6 ± 3. 3) minutes vs. (15. 6 ± 2. 5) minutes), central lymph node dissection ((25. 1 ± 5. 4) minutes vs. (24. 4 ± 6. 3) minutes) and total surgical time ((91.7 ± 11. 4) minutes vs. (96. 1 ± 13. 0) minutes). CONCLUSION: Application of 3D technique in endoscopic surgery can offer 3D vision of the surgical field, thus significantly shorten lobectomy time and more easily to achieve fine dissection and functional protection of recurrent laryngeal nerves, parathyroids and other vital anatomic structures.
