Thymoma surgery costs about $30,000-$40,000. As far as the current medical technology is concerned, the cost of surgery is not exactly the same from hospital to hospital. In a provincial-level tertiary hospital, thymoma surgery will cost about 30,000-40,000 yuan. All costs have about three parts: first, the pre-operative part. The special point is that thymus surgery needs to exclude myasthenia gravis, and it needs to do enhanced CT to show the relationship between the thymus tumor or mass and the surrounding large blood vessels and heart nerves, so the preoperative examination will cost about 5,000 yuan. Secondly, intraoperative costs include anesthesia, open or thoracoscopic or median sternotomy, sternal ligature, wire ligation or chest closure equipment, which is about 10,000 yuan. Third, the postoperative period requires active anti-infection to prevent and control complications such as lung infection.
