Adipofascial Flap Reconstruction for Pulp Defects: A Retrospective Study of Functional and Aesthetic Outcomes

Le résumé fourni par la source

Background: Injuries to the digital distal phalanx often result in functional impairments such as loss of grip and sensation, along with aesthetic challenges. Various reconstructive techniques, including the use of adipofascial flaps, have been explored to address these issues. The homodigital dorsal adipofascial reverse flap (HDARF) has demonstrated promising results in restoring both functionality and aesthetics. However, a comparative evaluation between adipofascial flaps and other commonly used techniques, such as V-Y advancement flaps and cross-finger flaps, remains limited. Objective: This retrospective study evaluates the long-term functional and aesthetic outcomes of adipofascial flap reconstructions for pulp defects, focusing on sensory recovery and patient satisfaction. Methods: Between 2010 and 2022, 20 patients (14 men, 6 women) with digital pulp defects underwent reconstruction using adipofascial flaps in a single-stage procedure. Injuries included avulsion and crush injuries, distributed across various digits. Sensory recovery was assessed using the Semmes–Weinstein monofilament test and two-point discrimination. Joint mobility, cold intolerance, and aesthetic satisfaction were also evaluated. Results: All flaps were successfully reconstructed within 24 h of trauma. Sensory recovery was excellent, with Semmes–Weinstein scores ranging from 1.65 to 2.83, comparable to the uninjured hand. Two-point discrimination averaged 1–5 mm in most cases. Cold intolerance persisted in four patients, and mild nail dystrophy was noted in three cases, with one case of nail absence. Aesthetic satisfaction was high in 19 patients. Conclusions: The adipofascial flap effectively restores function and aesthetics in pulp defects, offering superior sensory recovery, high patient satisfaction, and minimal complications. Its regenerative potential and adaptability make it a valuable option for fingertip reconstruction, supporting its continued use in clinical practice.
