In July 2013, a minimally invasive sternal countersink was successfully performed on a 12-year-old male child with a pheochromothorax. The Haller index of this child was 1.77. Immediately after surgery, the child’s chest became significantly flatter. The sternal reduction was performed in a way similar to minimally invasive funnel chest orthopedic surgery, which achieved a satisfactory treatment result with a small incision (about 3 cm of bilateral chest incision), no osteotomy, no impact on the integrity of the thorax, short operation time (about 1 hour), little bleeding (5-10 mL), quick postoperative recovery, and no need for lower chest drainage. This case is the first case of minimally invasive sternal sink in our hospital for chicken chest.
