Clinical study of dorsal ulnar artery flap in hand reconstruction

Soft tissue defects of hand with exposed tendons, joints, nerves and bone represent a challenge to plastic surgeons. Such defects necessitate early flap coverage to protect underlying vital structures, preserve hand functions and to allow for early rehabilitation. Becker and Gilbert described flap based on the dorsal branch of the ulnar artery for defects around the wrist. We evaluated the use of a dorsal ulnar artery island flap in patients with soft tissue defects of hand. Twelve patients of soft tissue defects of hand underwent dorsal ulnar artery island flap between August 2006 and May 2008. In 10 male and 2 female patients this flap was used to reconstruct defects of the palm, dorsum of hand and first web space. Ten flaps survived completely. Marginal necrosis occurred in two flaps. In one patient suturing was required after debridement and in other patient wound healed by secondary intention. The final outcome was satisfactory. Donor areas which were skin grafted, healed with acceptable cosmetic results. The dorsal ulnar artery island flap is convenient, reliable, and easy to manage and is a single-stage technique for reconstructing soft tissue defects of the palm, dorsum of hand and first web space. Donor site morbidity is minimal, either closed primarily or covered with split thickness skin graft.     

Large bilobed flap in the repair of face and neck defects

While the bilobed flap is an extremely useful flap and its usefulness in coverage of the small facial defects has been well described, there is no report related to its usage as an alternative to regional flaps, tissue expansion technique and free tissue transfers in the face and neck reconstruction. This report presents our experience with nine patients who had skin defects of their face and neck areas reconstructed with large bilobed flaps from adjacent areas. The results of the repair were satisfactory with respect to colour match, texture and functional properties. The purpose of this paper is simply to emphasize that this old and well-known technique for small-sized defects can also be suitable for reconstruction of large defects in the face and neck in selected cases.     

Correction of thumb deformities after burn: versatility of first dorsal metacarpal artery flap

In the management of a debilitated burned hand due to contractures, thumb reconstruction constitutes the most crucial part for a beneficial functional outcome. Among the limited local flap alternatives for the thumb, the first dorsal metacarpal artery flap, harvested from the dorsal aspect of the index finger can provide elastic, durable and sensate coverage for soft tissue defects after contracture release. In a 3-year period, neurovascular island first dorsal metacarpal artery flap was used in 14 patients suffering thumb deformities. The time elapsed after the underlying injury until reconstruction ranged from 5 months to 17 years. Follow-up revealed that all deformities were successfully treated with satisfactory functional recovery and cosmetic results. Donor site morbidity was minimal with an acceptable scar on the dorsum of the index finger and adequate tendon gliding without producing extension deficit. Our experience with management of deformities involving the thumb and/or adjacent thenar area revealed that the first dorsal metacarpal artery flap is a reliable local neurovascular island flap option, offering acceptable functional and cosmetic outcomes in respect to sensation, elasticity, durability and skin-match.     

The usefulness of the bilobed flap for lateral cheek defects

The cheek and nose are common areas for skin cancers. There are multiple approaches to surgical excision and reconstruction, depending on the size of defect, tissue quality, adjacent cosmetic units and hairline. An effective solution to skin defects of the lateral cheek is the bilobed flap. This flap tends to be underused in the lateral cheek area because primary closure and skin grafts are perceived to be easier methods of reconstruction. However, the use of the bilobed flap for lateral cheek and other defect closures is encouraged. There are several basic principles that are key when performing this flap. These components of the procedure are highlighted.
