ObjectiveTo explore the surgical techniques and safety of endoscopic thyroidectomy via breast areola approach. MethodsRetrospective analysis was conducted in 42 patients undergoing endoscopic thyroidectomy via breast areola approach, including 18 cases of thyroid adenoma and 17 cases of nodular goiter, 3 cases of nodular goiter with thyroiditis, 3 cases of primary hyperthyroidism, 1 case of thyroid carcinoma. Results40 cases were treated by endoscopic thyroidectomy via breast areola approach successfully, including 15 cases of thyroid adenoma resection, 15 cases of unilateral thyroid resection, 9 cases of bilateral thyroid resection, 1 case of unilateral thyroid resection plus lymph node dissection in central region. The average operation time was (96±21.9)min, and the average blood loss was (35±11.7)mL. The average hospitalization time was 3.5 days. Laryngeal nerve paralysis occurred in 1 case, postoperative chest subcutaneous ecchymosis in 2 cases. No other patients suffered from superior laryngeal nerve, recurrent laryngeal nerve and parathyroid injury. All incisions healed by first intention. 2 patients were converted to open surgery, 1 case of nodular goiter with thyroiditis and primary hyperthyroidism was due to intraoperative adhesion and unclear anatomy, the other case was due to small space to operate caused by severe goiter. ConclusionEndoscopic thyroidectomy via breast areola approach is a safe and feasible method, it can achieve a good cosmetic effect. The strict control of surgery indications and skillful surgical technique can assure successful operation.
