title: V-Y advancement for anal ectropion.
abstract: A V-Y advancement flap modified for anorectal use in reconstructive surgery for anal ectropion is described. The underlying external sphincter serves a dual function as the pivotal point for flap advancement and as the vascular pedicle to the dermal-subdermal plexus supplying the flap. This ensures viability and restores function to the newly created anus.
