Autoalloplast. An experimental and clinical study

F J Stucker

    Archives of Otolaryngology (Chicago, Ill. : 1960)
    |March 1, 1982
    PubMed
    Summary

    The novel autoalloplast, a polyamide mesh scaffold, allows tissue ingrowth for a reliable implant. This method proved superior to traditional grafts in animal and human studies for reconstructive surgery.

    Area of Science:

    • Biomaterials Science
    • Regenerative Medicine
    • Surgical Innovation

    Background:

    • Traditional alloplasts pose extrusion risks.
    • Autografts offer reliability but have limitations.
    • The autoalloplast concept merges alloplast convenience with autograft safety.

    Purpose of the Study:

    • To evaluate the feasibility of the autoalloplast concept.
    • To assess the biocompatibility and structural integrity of polyamide mesh implants.
    • To compare the autoalloplast's performance against other grafting materials.

    Main Methods:

    • A three-phase animal study involving polyamide mesh implantation.
    • Assessment of fibrous tissue ingrowth and graft assimilation.
    • Evaluation of implant explantation, reshaping, and reimplantation.
    • Comparative analysis of autoalloplasts versus autogenous cartilage, non-assimilated mesh, and Silastic.

    Main Results:

    • Polyamide mesh demonstrated successful fibrous tissue incorporation.
    • Harvesting and reimplantation of the mesh were feasible.
    • The autoalloplast exhibited superior resistance to traumatic extrusion compared to control materials.
    • Twenty-one human patients received successful autoalloplast implants with long-term follow-up.

    Conclusions:

    • The autoalloplast concept is feasible and safe.
    • Polyamide mesh can be biologically assimilated and utilized as a reconstructive graft.
    • This technique offers a promising solution for managing certain facial deformities in reconstructive surgery.
