Abstract
Dog bites to the face are common in children and often involve amputation of the lip or cheek resulting in a devastating facial injury. When feasible, replantation of the amputated lip segment provides the optimal cosmetic outcome. Here, we present the case of a partial upper lip replantation with delayed inset as a new treatment option. Revascularization of the central upper lip segment was enabled by anastomosis to a single labial artery. Inset compression at the time of initial closure caused arterial insufficiency. Therefore, a delayed, sequential inset was performed over the following 2 weeks resulting in an esthetically and functionally successful replantation. A comprehensive review of the literature on published lip replantation techniques is also provided and discussed. We add delayed inset to the armamentarium of the microsurgeon when faced with these difficult injuries.
