Objective To introduce the clinical application of the expanded scalp flap in the repair of baldness. Methods Based on area and shape of the baldness, two or three expanders were buried under the normal scalp galea around baldness. The scalp was expanded by intermittence injecting 0.9 % sodium chloride solution into expanders for 3 7 weeks, and then the expanded scalp flaps were used for repair of the baldness. Results Thirty expanders were used in twenty cases of patients with baldness, and all cases were satisfactory except two cases, in which the expanders exposed. Conclusion The treatment on baldness with expanded scalp flap is reliable. The donor site does not need graft skin. The scalp expansion may be the first choice in the repair of baldness.
