Congenital hairy nevi or giant congenital melanocytic nevi (GCMN) especially that of the face pose a great challenge to reconstructive surgeons. These unsightly lesions can be psychologically damaging to both parent and child. A variety of treatment options exist for the management of such cases. In this review article, we present two children who had a GCMN of their face managed with self-inflatable tissue expanders (osmotic tissue expanders [OTEs]) for single stage excision, and reconstruction is presented. The uses of self-inflating tissue expanders are now a regular choice for tissue cover in wide areas and in children.
