Various surgical techniques have been described for the release of syndactylized fingers. In our experience, the omega flap technique, which includes a dorsal truncated flap and an anchor incision on the volar side, stands out as a good technique to release syndactyly. Incidentally, in symbrachydactyly also, the fused digits can be released using this technique. Despite this, we could find no reference in the recent years. We would like to stress the ease and importance of this technique, hoping many practicing hand surgeons will benefit from this. Our purpose was to revisit this technique and expose it to the younger generation of hand surgeons. We have operated on 20 cases of syndactyly of different types-simple, compound, and complex-and 5 cases of symbrachydactyly. In all cases, the omega flap on the dorsum and anchor incision on the volar aspect of the finger forming 2 lateral palmar flaps were used. The release of syndactyly was satisfactory in all patients. There was no flap necrosis. None of these cases have required secondary surgery because the primary releases were adequate. Release of syndactyly had been a problem for centuries. Awareness of the disability was insufficient in earlier days; currently, they seek early medical care. The release should be complete. These children must be able to achieve the form and function of the hand, and additionally precision to work. We believe that the use of omega flap and anchor flap is a good procedure for syndactyly release.
