Abstract: Objective To evaluate the value of endoscopic thyroidectomy via thoracic-breast approach in patients with benign thyroid tumors. Methods A total of 40 patients with benign thyroid tumors who underwent endoscopic thyroidectomy via thoracic-breast approach from December 2019 to May 2021 in our hospital were selected as the observation group, another 40 patients with benign thyroid tumors who underwent open operation at the same period in our hospital were selected as the control group. A retrospective analysis was conducted on the two groups of patients. Results The operation time of the observation group was significantly longer than that of the control group （P<0.05）, and other operation indexes of the observation group were significantly better than those of the control group （P<0.05）. The total incidence rate of complications in the observation group was significantly lower than that in the control group （P<0.05）, and the appearance satisfaction rate in the observation group was significantly higher than that in the control group （P<0.05）. Conclusion Endoscopic thyroidectomy via thoraco-breast approach in patients with benign thyroid tumors can significantly reduce the incidence rates of intraoperative injury and postoperative complications, and improve patients' appearance satisfaction, despite extended operation time, and therefore it is worthy of clinical promotion.
