Aesthetic Considerations in Extremity Salvage and Reconstruction.

[LEARNING OBJECTIVES] After studying this article, the participant should be able to: 1. Have an in-depth understanding of the functional and aesthetic requirements of lower extremity reconstruction. 2. Describe the considerations for achieving an optimal aesthetic outcome in the primary reconstruction settings. 3. Describe modalities of secondary flap revision for achieving an optimal aesthetic outcome.

[SUMMARY] Significant advancements have been made in the management of lower extremity reconstruction since Dr. Taylor's seminal case in 1973. Improvements in our understanding of vascular anatomy and evolution of microsurgical techniques have allowed for an ever-increasing array of free tissue transfer options for lower extremity reconstruction. The resulting expertise has engendered a paradigm shift toward the reconstructive elevator approach, with increased emphasis on cosmetic results. In the primary setting, aesthetic considerations play an important role in precoverage wound preparation, flap selection, and harvest technique, with the goal of achieving excellent like-with-like reconstruction at the time of initial surgery. Flap selection should be made to best match the three-dimensional architecture of the wound, and take into account the defect thickness, flap thickness, flap composition, and pedicle length. Primary flap thinning and harvest in the superficial fascial plane has been shown to be an effective modality to address excess adiposity and improve contour. Despite these efforts, secondary procedures are often required to optimize the limb's final appearance and functional outcomes, particularly in the foot and ankle region. These include debulking, liposuction, and staged excisions. As the field of limb salvage keeps evolving, aesthetics will continue to play an important role in extremity reconstruction planning and execution.
