The bicoronal incision, popularized by Tessier, provides wide access to the orbits, nose, and zygomas as well as the cranium. But blood loss is unavoidable. We attempt to reduce the blood loss and the transfusion with tumescent technique. Athors had performed 17 cases of bicoronal incision between June, 2002 and march, 2003. 8 cases of them underwent the procedure with tumescent solution(Group A). 9 cases was done by usual manner(Group B). We analyzed 23 cases undergiong bicoronal incision for the blood loss and the transfusion amount. Intraoperative blood loss, postoperative transfusion was reduced at Group A. And the dissecting was easy. We think that tumescent technique contributes to reduce the bleeding, additionally reduce the postoperative transfusion.
