    Younger patients (<20 years) achieve better flap sensibility after cross-finger flap surgery. Sensibility recovery plateaus within one year post-operation, indicating optimal timing for surgical intervention.

    Area of Science:

    • Plastic Surgery
    • Reconstructive Surgery
    • Microsurgery

    Background:

    • Cross-finger flaps are a reconstructive technique used to restore digital coverage.
    • Assessing the long-term functional recovery, particularly sensory restoration, is crucial for patient outcomes.

    Purpose of the Study:

    • To evaluate the long-term sensory recovery in cross-finger flaps.
    • To identify factors influencing sensory outcomes, such as patient age and time since surgery.

    Main Methods:

    • A cohort of 51 patients who underwent cross-finger flap surgery were assessed 1-6 years post-operatively.
    • Two-point discrimination (TPD) was measured in the flap and compared to the contralateral normal hand.
    • The TPD difference was analyzed in relation to patient age and time elapsed since the operation.

    Main Results:

    • Patients under 20 years old demonstrated superior two-point discrimination (TPD) in their cross-finger flaps.
    • Sensory recovery in cross-finger flaps appeared to stabilize, reaching a plateau within the first year after surgery.

    Conclusions:

    • Younger age is a significant predictor of better sensory outcomes following cross-finger flap reconstruction.
    • The time course of sensory restoration suggests that maximal benefit is achieved within one year, guiding patient expectations and follow-up strategies.
