  • Ex vivo assessment of the microclip's secure fastening capability on vocal fold tissue.
  • In vivo implantation studies to evaluate bioabsorbability and potential adverse effects.

    • Main Results:

    • The microclip demonstrated secure attachment to the vocal fold tissue during ex vivo testing.
    • In vivo studies confirmed the bioabsorbability of the magnesium-based microclip.
    • No significant adverse side effects were observed in the in vivo evaluations.

    Conclusions:

    • The novel magnesium-based bioabsorbable microclip is a viable miniature device for laryngeal wound closure.
    • The microclip's secure fastening, bioabsorbability, and safety profile suggest its potential as an implantable device.
    • This innovation may overcome limitations of current technologies in laryngeal microsurgery, improving healing outcomes.
