Experience in microsurgical treatment of complete scalp avulsion

BACKGROUND: Avulsion of the scalp is a rare destructive event worldwide. Before the emergence of microsurgery, skin transplantation, flap transplantation, greater omentum transplantation, and other methods were once widely used. However, replantation offers the optimum reconstruction. METHODS: Six cases of complete avulsion injury of a large scalp treated from May 2017 to May 2020 were retrospectively analyzed. Under the microsurgery technology, the wound was cleaned and explored, and the appropriate arteriovenous anastomosis was selected. Preoperative blood preparation and skin preparation were actively performed. Postoperative strict nursing and observation of the blood supply of replanted scalp were performed. Regular outpatient follow-up after discharge was performed. RESULTS: Replantation was successful in 5 cases and failed in 1 case, and in 1 case the occipital scalp (approximately 10% of the scalp area) died and crusted 2 months after the operation. After 6 to 24 months of follow-up, all patients were satisfied with the reconstructed appearance. CONCLUSIONS: Superb microsurgical technique and more detailed anatomical knowledge are the key conditions for successful complete scalp avulsion replantation. Compared with other methods, successful replantation can achieve the best aesthetic and functional results.
