Replantation of amputated facial tissues with microvascular anastomosis.

Abstract

A challenge to the microsurgeon is perfecting the technique of replantation of small pieces of facial tissue, mainly because of the extremely small size of the arteries as well as a lack of suitable veins for drainage. In the past 4 years, we have had seven cases of facial amputations, which included one scalp, two nasal tips, two ears, one lower lip, and one eyebrow. All of these patients were replanted/revascularized by microvascular anastomosis. Only two of the cases had suitable veins for anastomosis. Alternative techniques used for improving venous outflow were arterio-venous fistula, chemical leeches, and pin pricks. Four of the cases were completely successful, two cases had partial loss of the replant, and one case failed due to absence of venous drainage. In facial amputation, an aggressive microsurgical attempt will result in more tissue surviving and a better cosmetic outcome than in any other reconstructive procedures.
