Abstract

Scalp avulsion is rare injury that has serious consequences, including hospitalization, economic loss, devasting disfigurement, and psychological effects on the patient. Microvascular surgery now allows an initial chance for successful replantation and one-stage reconstruction. The need for secondary reconstructive procedures after a successful replantation is minimal. Our one year experience with 2 patients who suffered from avulsion of partial scalp is reviewed. Each patient got long hair entangled in the uncovered rotated machines and underwent replantation using microsurgical technique. Replantations have been accomplished using only arterio-venous and venous-venous anastomosis, without arterio-arterial anastomosis in 2 cases, because of unidentification of suitable arteries. The possible explanation for the success of the operation is the paucity of valves that exist in the venous network of the scalp and forehead. The final results were good. In the follow-up period, both experienced regrowth of hair in the scalp with light touch sensation.
