'Tissue clay'. A new technique for augmentation rhinoplasty.

M E Sachs

    Archives of Otolaryngology--Head & Neck Surgery
    |March 1, 1987
    PubMed
    Summary

    A novel "tissue clay" made from microfibrillar collagen and whole blood effectively augments the nose in rhinoplasty. This technique shows excellent esthetic and functional results with no complications and minimal resorption over four years.

    Area of Science:

    • Plastic Surgery
    • Biomaterials

    Background:

    • Dorsal augmentation in rhinoplasty aims to improve nasal aesthetics and function.
    • Current augmentation materials have limitations, including donor site morbidity, infection, and unpredictable resorption.

    Purpose of the Study:

    • To evaluate the safety and efficacy of a novel "tissue clay" for dorsal augmentation in rhinoplasty.

    Main Methods:

    • A technique using microfibrillar collagen (Avitene) combined with autogenous whole blood to create a sculptable "tissue clay" was employed.
    • This material was used for dorsal augmentation in 58 patients over four years.
    • The "tissue clay" solidifies within one week, mimicking bone texture.

    Main Results:

    • Long-term (four-year) follow-up documented successful nasal augmentation up to 1 cm in height.
    • The average resorption rate over two to four years was 16%.
    • No complications were reported in any of the 58 cases.

    Conclusions:

    • The microfibrillar collagen-based "tissue clay" is a safe and effective material for dorsal augmentation in rhinoplasty.
    • The technique yields excellent esthetic and functional outcomes with predictable results.
    • This method offers a promising alternative for nasal augmentation procedures.
