Immediate Z-plasty for semicircular wounds.

F N Gahhos, R I Simmons

    Plastic and Reconstructive Surgery
    |September 1, 1987
    PubMed
    Summary

    Immediate Z-plasties can prevent the "trapdoor" deformity common in facial laceration repairs. This surgical technique rearranges tissue during initial wound closure, improving cosmetic outcomes for curved lacerations.

    Area of Science:

    • Plastic Surgery
    • Wound Healing
    • Dermatologic Surgery

    Background:

    • Simple layered repair of curved lacerations often leads to scar contraction and a "trapdoor" deformity.
    • This deformity involves the elevation of the central wound area due to scar tissue pulling.
    • Traditional approaches have discouraged immediate tissue rearrangement during initial repair.

    Observation:

    • Five patients with curved and semicircular facial lacerations underwent immediate single or multiple Z-plasties during initial repair.
    • The Z-plasty technique involves interdigitating triangular flaps to break up linear tension.
    • This approach was applied consecutively to all eligible patients presenting with these specific laceration types.

    Findings:

    • None of the five patients developed the characteristic "trapdoor" deformity following the Z-plasty repair.
    • The immediate use of Z-plasties effectively addressed the tension lines inherent in curved lacerations.
    • Scar contraction was managed by the geometric rearrangement of tissue, preventing central elevation.

    Implications:

    • Immediate Z-plasties are a viable and effective strategy for acute management of semicircular and curved facial lacerations.
    • This technique can significantly improve aesthetic results by preventing the "trapdoor" deformity.
    • The findings suggest a shift in traditional practice, advocating for early tissue rearrangement in specific laceration scenarios.
