[Sasumata(U+I) shape skin incision for the surgery through median sternotomy].

: Since April, 1994 we have tried median sternotomy in a new skin incision which resembles to "Sasumata", a Japanese historical weapon of police, for the surgery of eleven patients with thymic disease or lung cancer for cosmetic reasons. An U-shaped skin incision in the upper half portion of the breast and a vertical incision from the bottom of "U" to xyphoid process were made. A comparison was made in eight patients with former conventional method, a linear incision on the sternum. The new incision was useful not only for cosmetic reasons but also for the following reasons; enough operation area, good lymph node dissection from lower neck to upper mediastinum without additional collar incision, and good healing of the skin. There were no differences between the two incision groups on operation time, bleeding volume and hospital stay after surgery. In a postoperative research almost all patients have been satisfied with the new incision.
