Repair of scalp defects using a tissue expander and Marlex mesh

A simple technique using Marlex mesh and a tissue expander to cover scalp defects is described and two patients are presented. This technique is suitable for medium-sized defects that cannot be closed primarily. Marlex mesh is sutured to the wound edges in lieu of a temporary skin graft and to prevent enlargement of the defect during tissue expansion. The tissue expander is placed under adjacent normal scalp in a subgaleal pocket developed through the scalp defect. The scalp defect is closed secondarily using the expanded scalp flap. This technique was performed in two patients with satisfactory results. Marlex mesh obviates the need for a temporary skin graft to cover the scalp defect.
