Lip Replantation: Mid-term Follow-Up and Aesthetic Revision.

Upper lip trauma with tissue loss due to dog bites is relatively common; however, reports of replantation of amputated lip tissue remain rare. Even fewer studies have documented long-term changes in graft tissue or the implementation of revision surgery after replantation. We present a case of upper lip replantation after a dog bite, with follow-up and subsequent revision surgery conducted. Despite the absence of venous anastomosis, graft survival was achieved using medicinal leeches. Revision surgery was eventually performed after a follow-up period of 2 years and 8 months. Because replanted tissue may undergo changes over time, long-term follow-up observation with consideration for revision surgery is necessary to achieve optimal outcomes.
