Purse-string closure of scalp defects following tissue expansion: an effective aesthetic alternative.

摘要

Primary closure of scalp defects under tension can be complicated by scar widening and alopecia, and large defects usually require the use of local flaps, skin grafts or free flaps. Tissue expansion facilitates the use of local flaps to cover large defects, but multiple expanders and complex flaps with extensive incisions may cause significant scars and alopecia. We describe a purse-string closure of expanded scalp tissue following excision of a large congenital nevus sebaceous. This scalp reconstructive technique minimises iatrogenic scars and uses the predictable forces of scar contracture and skin re-draping to achieve a superior aesthetic result.
