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.
显微外科医生面临的一项挑战是完善小块面部组织再植技术,主要原因是动脉极其细小且缺乏合适的引流静脉。在过去4年里,我们共收治了7例面部离断伤患者,其中包括1例头皮、2例鼻尖、2例耳朵、1例下唇和1例眉毛。所有这些患者均通过微血管吻合进行了再植/血管重建。只有2例患者有合适的静脉用于吻合。用于改善静脉回流的替代技术包括动静脉瘘、化学水蛭疗法和针刺。4例完全成功,2例再植组织部分坏死,1例因无静脉引流而失败。在面部离断伤中,积极的显微外科手术尝试将比其他任何重建手术使更多的组织存活,并获得更好的美容效果。
