Conventional reversed sural flaps have been used to cover heel defects; however, the experience of the authors indicates that the reach of these flaps falls just short of the critical area to be covered. With the limitation being the location of the flap (the middle third of the leg), the authors thought that if the flap territory were extended proximally, they would have a super flap with immense potential. Nevertheless, the critical question remained, "How far?" The massive earthquake in January of 2001 in Gujarat, India, made medical personnel pressed for time, manpower, resources, and other ancillary supports. The authors were forced to make some innovations in their management of extensive heel defects. On the basis of preexisting anatomic studies, they developed the possibility of using distally based neuroskin flaps of huge dimensions that extend well beyond the conventional confines. The versatility of this extended, reversed, neuro-fasciocutaneous flap in regard to its reliability and safety, despite its huge dimensions, is commendable. The hallmarks of this successful extended sural flap, which the authors used to cover large heel defects, were basically accurate understanding of the anatomy and the use of Doppler to map the perforators and the lesser saphenous vein for inclusion in the lie of the pedicle. The authors share their experience of five cases of difficult heel reconstructions salvaged with this flap, which made them attempt to define maximum flap dimensions that can be harvested. The authors learned that the flap can be extended proximally to include the entire upper one-third of the leg posteriorly, drastically improving its reach and size, without compromising safety. The largest flap used measured 17 x 16 cm, far more than ever reported in the literature. The flaps truly deserve the classification of "super," which is usually reserved for Ponten's flaps.
The concept of including external oblique aponeurosis along with the time-tested groin flap as a single vascularized unit heralds a versatile and unique application in the armamentarium presently available. This concept, though simple, has not been previously reported in the world literature. In view of its potential benefits and simplicity, we felt the need to bring this concept to the attention of our colleagues.
Context:Despite the abundance of techniques for the repair of Hypospadias, its problems still persist and a satisfactory design to correct the penile curvature with the formation of neourethra from the native urethral tissue or genital or extragenital tissues, with minimal postoperative complications has yet to evolve.Aim:Persisting with such an endeavor, a new technique for the repair of distal and midpenile hypospadias is described.Materials and Methods:The study has been done in 70 cases over the past 11 years. The “Forked-Flap” repair is a single stage method for the repair of such Hypospadias with chordee. It takes advantage of the rich vascular communication at the corona and capitalizes on the established reliability of the meatal based flip–flap. The repair achieves straightening of the curvature of the penis by complete excision of chordee tissue from the ventral surface of the penis beneath the urethral plate. The urethra is reconstructed using the native plate with forked flap extensions and genital tissue relying on the concept of meatal based flaps. Water proofing by dartos tissue and reinforcement by Nesbit's prepucial tissue transfer completes the one stage procedure.Statistical Analysis:An analysis of 70 cases of this single stage technique of repair of penile hypospadias with chordee, operated at 3 to 5 years of age over the past 11 years is presented.Results and Conclusion:The Forked Flap gives comparable and replicable results; except for a urethrocutaneous fistula rate of 4% no other complications were observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
