ABSTRACT: This article is to review the role of microsurgery in facial trauma reconstruction. Microsurgery was developed since 1960s and had been applied on facial trauma from 1970s to treat amputated scalp, nose, ear and lip. Microsurgical replantation of scalp and small parts of face restores function and achieves aesthetic results, but small size of vessels and venous drainage problems are most technical challenging. In this article, we reviewed many talented authors’ work to solve those problems in facial tissue replantation. If defects are huge, we need microsurgical free flaps for reconstruction. The current workhorse is anterolateral thigh flap and we reviewed the versatility and new concepts of the flap. Development of perforator flaps was another milestone of flap reconstruction because of better cosmetic result and lower donor site morbidity. We reviewed the concepts, history and application of perforator flaps. Finally, facial replantation developed in recent 5 years to treat extremely large facial defects which cannot be reconstructed with microsurgical flaps and traditional flaps alone. The task is complex and needs a large team to support the whole procedure. We also reviewed the facial allotransplantation, which is the ultimate application of microsurgery in facial trauma reconstruction.
