The omega flap technique offers an effective method for syndactyly release in both syndactyly and symbrachydactyly cases. This surgical approach ensures satisfactory digit separation with no flap necrosis, avoiding secondary surgeries.

Area of Science:

  • Plastic Surgery
  • Hand Surgery
  • Congenital Hand Anomalies

Background:

  • Syndactyly (fused digits) and symbrachydactyly (shortened digits) are congenital conditions requiring surgical correction.
  • Various surgical techniques exist for syndactyly release, but the omega flap technique has seen limited recent documentation.

Purpose of the Study:

  • To revisit and highlight the efficacy of the omega flap technique for syndactyly and symbrachydactyly release.
  • To reintroduce this valuable surgical method to contemporary hand surgeons.

Main Methods:

  • The study involved 20 cases of syndactyly (simple, compound, complex) and 5 cases of symbrachydactyly.
  • The omega flap technique, utilizing a dorsal truncated flap and a volar anchor incision to create lateral palmar flaps, was applied in all cases.

Main Results:

  • All 25 patients achieved satisfactory syndactyly release.
  • No instances of flap necrosis were reported.
  • Primary releases were adequate, eliminating the need for secondary surgeries in any case.

Conclusions:

  • The omega flap technique, combined with an anchor incision, is a simple, effective, and reliable method for releasing syndactyly and symbrachydactyly.
  • This technique facilitates complete digit separation, restoring form and function for improved hand dexterity.
