Abstract: This article reports the experience of surgical treatment of two cases of retrosternal goiter combined with hyperthyroidism with tracheal tenderness.Case 1 was a 54-year-old woman and Case 2 was a 73-year-old woman,both diagnosed with retrosternal goiter on imaging,with Case 2 combined with hyperthyroidism.In both cases,total thyroidectomy and resection of the retrosternal mass were successfully completed through a low neck collar incision without sternal splitting.In response to the intraoperative finding of tracheomalacia,the anterior wall of the trachea was suspended and fixed with a No.4 silk thread in the shape of an "8" suture.Case 2 was pretreated with dexamethasone to prevent hyperthyroidism.There were no serious postoperative complications and follow-up showed a patent airway.

Key words: retrosternal goiter, hyperthyroidism, tracheal tube suspension with softening
