Bilateral modified V-Y advancement flaps for closing meningomyelocele defects.

Abstract

Various reports describe surgical techniques for closing a meningomyelocele defect. We have used a combination flap consisting of a vertical bipedicled flap and V-Y advancement flap and used this technique in the successful repair of 11 meningomyelocele defects. The vertical bipedicled flap enhances the blood supply to the V-Y advancement flap with no sacrifice of muscle tissue. This flap can easily be moved to the midline, and the donor area can be primarily sutured with no complications. Our method has several advantages compared with previously reported methods: 1) no skin grafts are needed; 2) no muscle tissue is killed; 3) it is simple and easy, leading to less blood loss and minimal operative time; and 4) it is safe and produces reliable results while eliminating wound dehiscence and skin necrosis.
