    Summary
    This summary is machine-generated.

    The O-to-Z plasty offers an effective surgical solution for closing circular defects in the eyelids and facial areas. This technique helps ophthalmic plastic surgeons achieve smooth closures, often avoiding the need for skin grafts.

    Area of Science:

    • Ophthalmic Plastic Surgery
    • Dermatologic Surgery

    Background:

    • Closing circular defects in the eyelids, canthal areas, face, and neck is a complex surgical challenge.
    • These defects often result from the excision of benign or malignant tumors, requiring precise reconstruction.

    Purpose of the Study:

    • To present the O-to-Z plasty technique for reconstructing medium-sized circular defects.
    • To highlight the advantages of this method in ophthalmic plastic surgery.

    Main Methods:

    • The O-to-Z plasty involves undermining skin around the circular defect.
    • Two parallel incisions are made along lines of cleavage, allowing skin advancement.
    • The defect is converted into a Z-closure for tension-free approximation.

    Main Results:

    Related Experiment Videos

    • This technique facilitates a smooth and firm closure of surgical defects.
    • It effectively avoids the formation of "dog-ear" deformities.
    • Skin grafts can be obviated for many small to moderate circular defects.

    Conclusions:

    • The O-to-Z plasty is a valuable procedure for ophthalmic plastic surgeons managing circular defects.
    • It offers a reliable method for reconstruction, improving aesthetic and functional outcomes.
