Autolyzed, antigen-extracted, allogeneic (AAA) bone grafts show excellent remodeling and integration in plastic surgery. This bone allograft offers a safe alternative to autografts with minimal complications.

Area of Science:

  • Plastic Surgery
  • Regenerative Medicine
  • Biomaterials

Background:

  • Autolyzed, antigen-extracted, allogeneic (AAA) bone is an osteoinductive allograft.
  • AAA bone has been used in various plastic surgery procedures to improve patient profiles.

Purpose of the Study:

  • To evaluate the efficacy and safety of AAA bone implants in plastic surgery.
  • To assess the remodeling, resorption, and complication rates of AAA bone grafts.

Main Methods:

  • A retrospective study of 207 patients who received AAA bone implants for facial augmentation.
  • Procedures included mandibular correction, genioplasty, forehead reconstruction, midface augmentation, and rhinoplasty.
  • Follow-up ranged up to 72 months, including reoperations to assess implant status.

Main Results:

  • AAA bone implants remodeled into host bone within months in most cases.
  • Less than 3% of implants were lost due to infection.
  • Secondary resorption was minimal except in rhinoplasties (25%) due to tension and scar formation.
  • No late complications associated with alloplastic implants were observed.

Conclusions:

  • AAA bone is a convenient and effective alternative to autografts, especially in well-vascularized recipient beds.
  • Its biodynamic remodeling minimizes risks of perforation and late complications.
  • Careful patient selection is advised for nasal augmentation due to potential resorption.
